The Inland Manufacturing Division of General Motors was organized in 1922 for the manufacturing of wood-wrapped steering wheels. Their location in Dayton, OH included the buildings of the then defunct Dayton Wright Airplane Company with the shape of one of the buildings becoming part of the Inland logo.

In November 1941 Inland became the second of what would eventually become ten companies contracted by U.S. Army Ordnance to produce the U.S. Caliber .30 Carbine. Inland was instrumental in the early years before mass production in perfecting the Winchester design. Inland was the first of these companies to start mass production and one of only two who continued until the end of carbine production in August 1945. Inland manufactured over 2,630,000 carbines, more than three times any of the other manufacturers. They were the only company to manufacture the folding stock Model M1A1 Carbine and one of only two companies to manufacture the select-fire Model M2 Carbine.
After WWII Inland returned to manufacturing automotive parts for GM. The Inland Manufacturing Division of General Motors was eventually merged with other companies and finally passed into history in 1999. The buildings that had housed Inland were demolished between March and June 2014. The Wright Airplane Company hangars were spared due to their historical significance.
The carbines manufactured by the Inland Division of General Motors during WWII were, and still are, the most commonly encountered U.S. Carbines manufactured under contract to U.S. Army Ordnance.

On June 19, 2012 two trademark applications were filed with the United States Patent and Trademark Office by Douglas Brannon, a corporate attorney. One application was for the logo and its design by Chiappa Firearms LLC at 6785 West Third Street in Dayton, Ohio (granted June 30, 2015 - Registration #4764882). The second was for the name 'INLAND MANUFACTURING' by Ronald Norton at 6785 West Third Street in Dayton, Ohio (granted September 20, 2016 - Registration #5045779). Both indicate the date of first use in commerce as October 14, 2014.
The property at 6785 West Third Street in Dayton, Ohio was purchased by Chiappa Firearms in July 2009. Chiappa constructed a building on this property with 1959 sq. ft. of office space and a 5056 sq. ft. warehouse that served as the U.S. headquarters for Chiappa Firearms. Ron Norton served as the president of Chiappa USA at this location. Chiappa's replicas of the M1 Carbine in .22 long rifle and 9mm were initially shipped to wholesalers and retailers from this location.
Ohio corporate records indicate Inland Manufacturing became an Ohio Limited Liability Company on September 3, 2013. Attorney Douglas Brannon is indicated as the registered agent. The same day Ares Capitol LLC was incorporated with Brannon as their registered agent.
On March 21, 2014 Chiappa Firearms sold the property and buildings at 6785 West Third Street in Dayton to Ares Capitol, LLC. Chiappa relocated their USA HQ to a warehouse they had purchased in December 2013 at 1415 Stanley Ave., Dayton, OH. Since this date Inland Manufacturing with Ron Norton as their president has been operating from the Third St. location. Norton has indicated he left Chiappa Firearms in 2013 to serve as president of Inland Manufacturing.
Inland's website domain name was obtained in May 2014. Inland offers replacement parts from a second website, InlandDepot.com. The sole distributor for the items offered by Inland Manufacturing is MKS Supply located at 8611-A North Dixie Drive in Dayton, Ohio 45414. The Inland Manufacturing website indicates MKS Supply as the point of contact for all questions. All retail firearm sales are conducted through Inland's distribution network.
Inland Manufacturing .30 Caliber Carbines
Inland Manufacturing initially offered three carbine models along with several 1911 style handguns. Retailers began offering Inland's carbines during the Spring of 2015. Since then Inland has been adding additional carbine models that are variations of their basic M1 carbines. All are built using the same receivers and parts. The differences are barrel length, type of stock or finish, type of handguard and a few accessories such as their flash suppressor. Inland indicates their carbines are 100% manufactured in the USA.

A number of firearm related publications have authored information and/or videos on the carbines offered by Inland Manufacturing. Perhaps the most notable being a series of articles that have appeared in 'The American Rifleman' magazine and a video produced by Guns & Ammo magazine. The media attention has garnered a lot of interest in the carbines made by Inland Manufacturing. The main focus of the media has been the .30 caliber carbines manufactured during WWII with an introduction to the carbines currently being manufactured by Inland Manufacturing. These have not included a detailed examination and testing of the carbines.
The M1 Carbine
Manufactured by
the modern day
Inland Manufacturing
Auto-Ordnance has been manufacturing commercial M1 carbine replicas since 2005. The receiver and majority of parts used by Inland Manufacturing are manufactured by the companies who have been making and continue to make the same receiver and parts for Auto-Ordnance carbines. The part numbers used by Inland Manufacturing are the same as Auto-Ordnance. Both use the same manual with the name and information for their particular company.
In choosing to use the same sources as Auto-Ordnance Inland inherited some of the problems Auto-Ordnance has been experiencing. This is where the carbines produced by these two companies begin to differ in that Inland has taken extra steps to correct some of these problems and deficiencies. While at the same time they have created a few problems specific to their own.
The carbines manufactured by both Auto-Ordnance and Inland Manufacturing are replicas of the carbines manufactured for the U.S. Army Ordnance during WWII. Some of the parts are interchangeable with their GI counterparts, some are not. The parts made for and used by Inland and Auto-Ordnance are interchangeable with one another providing more than one source for replacement parts.
Break-in Period
Inland Mfg and Auto-Ordnance carbines purchased new typically have a break-in period of about 250-300 rounds. One of the issues common during this break-in period is occasional failure of the bolt to move fully forward, rotate and lock into the receiver causing a failure to fire. Occasionally during firing the bolt sometimes fails to travel far enough to the rear to cock the hammer. When the trigger is pulled the hammer is in the forward position and unable to strike the firing pin.
During this time the finish along the top of the bolt may wear quickly and/or become scratched. This is caused by a failure to properly finish machine the inside of the receiver to remove any metal left from the casting and insure the path of the bolt is straight and smooth. Failure to properly machine the slide's cam cut can also impede the movement of the bolt (see below). Failure to properly finish machine the surfaces on the right side of the receiver creates additional friction impeding the slide and bolt in addition to removing the finish where the slide and receiver come in contact with one another.
The problems usually tend to lessen the more the carbine is fired. The repeated movement of the parts eventually wear down the areas of resistance.
The Stock Group The stocks and handguards used by Inland are manufactured by the Altamont Company in Thomasboro, IL. Inland replicates the crossed cannons cartouche used by U.S. Army Ordnance inspectors at the Inland Division of GM during WWII Stocks feature a long barrel channel and are absent the wood crosspiece support forward of the trigger housing, replicating the design of an M2 stock. The cut of the wood under the recoil plate and absence of a selector switch cutout replicate the design of an M1 stock. Stocks manufactured by S.E. Overton for the Inland Division of GM were identified by placing the letters IO in the slingwell. Inland replicates these markings. The stocks manufactured by Altamont have not included the proper slingwell cut to allow the use of an oiler and sling. For the first couple years Inland corrected this by cutting a quarter moon shape in the slingwell (arrow) to enable use with their included sling and oiler. This has been corrected with their later stocks. The 1945 model includes the bayonet lug with barrel band. The bayonet lug is absent on the 1944 Model to comply with states having laws banning bayonet lugs. Stocks and handguards manufactured by Altamont for the M1 carbines are approximately 1/4' shorter than their GI counterparts and the majority of all other commercially manufactured M1 carbine stocks. If replacing only the stock or handguard this requires the replacement to be specifically for an Inland Mfg or Auto-Ordnance carbine. Using stocks and handguard with other than these requires replacing both the stock and handguard for the barrel band to fit properly. Note the barrel band spring fails to engage the notch in the barrel band for holding the barrel band in place. Buttplates and their pattern used by Inland Manufacturing match those used by Auto-Ordnance. |
The Receiver Group The receivers used by Inland Manufacturing are cast by Lamothermic Corporation in Brewster, NY. The same mold is used to cast receivers for Auto-Ordnance. Lamothermic was also used to cast the receivers used with the late production carbines by Israel Arms International in Houston, TX. Hardness tests of the receivers have indicated they are hardened to within GI specifications (Rc 38-45). A removable plate inside the mold is used to cast the U.S. Carbine Cal .30 M1 markings. The plate can be swapped out with a different plate to change the markings. To separate the receivers made for Inland Mfg from those made for Auto-Ordnance Lamothermic engraves the name of the company along with the serial number on the bottom of the receiver. The only difference between the receivers used by the two companies are the markings cast in the receiver. The casting process leaves excess or uneven metal in various locations on the receiver. Machining the ridges, uneven areas and finish machining to final specifications is left to the resources and discretion of the manufacturer. As can be seen in these series of photographs the degree to which this machining has been done either by and/or for Inland Mfg has varied but has not been consistently smooth. The inconsistent machining and/or lack of finish machining has been fairly consistent. The end result being varying degrees of wear and/or damage to the parkerized finish and metal on various parts that come in contact with each other. To include the right side of the receiver where the slide travels back and forth and the top of the bolt as it moves back and forth inside the receiver (see below). Note the uneven surfaces along the right side of the receiver. Also inconsistent has been the amount of force necessary to remove and replace the pin securing the trigger housing to the front of the receiver often requiring the use of a punch and hammer. Note the top of the rear wall of the magazine well is resting against the receiver. The receivers cast by Lamothermic for both Inland and Auto-Ordnance have shown varying degrees of warping along the bottom of the receivers that has been absent any machining. Forcing the front of the trigger housing upward to insert or remove the trigger housing pin may secure the two together but the greater the difference in alignment the greater the likelihood of altering the fit and/or performance of other parts that rely on proper alignment. One example is the angle at which the magazine sits as the bolt passes over it to chamber a cartridge. Use of an alignment mark to begin alignment of the barrel to the receiver. Barrels used on the original WWII carbines have an extension on the chamber end of the barrel referred to as a barrel skirt. The purpose of the skirt is to guide bolt into alignment with the chamber face. The receiver mold used by Lamothermic has been designed to include a substitute for this purpose, thereby eliminating the need for the barrel skirt. The Inland name and serial number are added at some point after the casting process. The milled adjustable rear sight appears to have been manufactured by Kensight, a division of KNS Industries. |
The Barrel Group Barrels used by Inland Manufacturing (and Auto-Ordnance) are manufactured by the Green Mountain Rifle Barrel Company in Conway, NH. The barrels have 4 lands and grooves. Inland's front sights are cast. They are secured to the barrel using a key and roll pin. Inland Manufacturing is the only commercial carbine manufacturer who has added their name to the barrel in an effort to replicate the original barrel manufacturers of WWII. Inland adds the markings after the barrel has been finished. The device used to create the markings creates the smoothed metal circling the barrel around the markings. Green Mountain Rifle Barrel Company manufactures the barrel using a cast gas piston housing swaged to the barrel. The wear on the side of the cylinder was caused by the slide. A word of CAUTION BEFORE FIRING carbines made by Inland Mfg (or Auto-Ordnance): The piston is held in place by the gas piston nut (white arrow). The nut is threaded and staked to the gas piston housing to prevent it from rotating out of the gas cylinder. Physically check the gas piston nut to make sure it's tight. The design of these nuts does not include the recessed areas specific for staking and holding the nut in place that was mandatory on carbines made to Ordnance specifications during and after WWII. Historically the stake marks as applied on the gas piston nuts used by the modern day Inland Mfg and those used by Auto-Ordnance have been insufficient to secure the nut in place. Check that the nut is tight before you fire the carbine and periodically thereafter to make sure it stays in place. Note the mold mark along the top of the barrel between the gas piston housing and receiver. Also the two silver spots on top of the barrel above the chamber. Variations of this method of barrel manufacture have been used by other earlier commercial carbine manufacturers. Winchester and Inland used a variation of this method when making the barrels for their first carbine prototypes. |
The Bolt GroupInland's bolts and firing pins are machined from forged steel. Their extractors are cast then hard chromed. Inland has chosen to use round bolts on their carbines. They offer the flat bolt version on their online store as an optional replacement. The only difference between the two is the flat bolt requires extra machining to remove part of the rounded top of the bolt to produce a slightly lighter weight bolt. Both designs are equal in strength when hardened properly. A Note regarding Compatibility The bolts made and used by Inland Mfg are interchangeable with those made and used by Auto-Ordnance. Although almost imperceptible the bolts used by Inland Mfg and Auto-Ordnance are not made to military specifications. Their bolts are slightly longer, the left locking lugs are slightly shorter, the right locking lugs are machined different and the hole for the extractors is slightly smaller. Keep in mind these carbines are replicas of the carbines manufactured for Ordnance during WWII and though not made to military specifications the various parts are made to specifications that enable them to work with one another. The tolerances used to manufacture these parts are not as stringent as those used by the companies contracted to manufacture carbines and parts for Ordnance during WWII. This sometimes allows interchangeability with their GI counterparts, sometimes not. Be aware that should you decide to replace the bolt on an Inland Mfg carbine with a surplus GI bolt or any bolt other than those made for Inland or Auto-Ordnance you should check the head space of the bolt with the carbine you plan on using it with before you fire the weapon. The difference in bolt length may make the replacement bolt unsafe to use in the Inland Mfg carbine. Inland initially used cast extractors parkerized to match the finish of the bolt and carbine. The extractors had a tendency to break. For a short time Inland replaced the original extractors with extractors machined from forged steel to military specifications. These were replaced with cast extractors that have been hard chromed as have been used by Auto-Ordnance for years. These are the only two companies who have used hard chromed extractors.
Commercial Inland Mfg Round BoltsRear of right bolt lug It is recommended the right bolt lug of the commercial Inland bolts be visually monitored on a regular basis (every couple hundred rounds fired) for deformed metal as shown above. Wear of the finish is normal, damage to the metal is not. If the metal appears to be slightly altered continue to monitor it. A Rockwell hardness test isn't necessary. If the bolt has this issue it will become readily apparent as the damage worsens with every 200-300 rounds. If and when the issue has been resolved you will know it's not an issue with your carbine by monitoring it and finding no damage to the metal. Also remember to monitor the rear of the bolt over time as with any commercial bolt. If you eventually decide to replace the bolt the flat bolts made for and used by Auto-Ordnance are one option. They have not experienced these issues and are of the same dimensions as the Inland bolts. |
The Slide
The slides used by Inland are also cast by Lamothermic Corporation. Hardness tests have shown
they have been hardened to GI specifications for hardening of the slide (Rc 40-45). The damage
to the front and rear of the right bolt lug noted above can be expected from the interaction of a
properly hardened slide with a bolt hardened below GI specifications.

Note the small distance between the edge of the spring hole and the rear edge of the cam cut.

Note the damage inside the front of the cam cut for the right bolt lug
The slide cam cut is usually absent finish machining. The angles within the cam cut appear to contribute to
failures of the bolt to smoothly move forward and into the locked position. During the firing of the first
200-300 rounds the movement of the bolt becomes smoother as the bolt and cam cut alter one another.

The Trigger Housing Group
The hammer and trigger appear to have been milled from forged steel. Machining can
remove traces of casting mold marks but the number of parts that were cast and not
machined on this carbine infers these two parts were likely made from forged steel.
The trigger housing, sear, safety and mag catch were cast and do not appear to have
been machined.
The plungers on either end of the safety/mag catch spring are not
secured to the spring. Caution should be exercised if removing or installing them.
The spring tension will launch the plunger behind the mag catch with enough force
to cause injury to an eye and/or make it difficult to locate the plunger.

The spring tension will launch the plunger behind the mag catch with enough force
to cause injury to an eye and/or make it difficult to locate the plunger.
The hole through which the trigger spring is installed has vertical edges from casting that were not machined to complete the
circular opening. They prevent the use of a trigger spring tool to install the trigger spring. They also prevent the trigger spring
from being installed through the rear of the hole in the normal manner.
The spring can be inserted from the rear if oriented upright and pulled over the rear of the trigger with a screwdriver. It can also be
inserted through the front side of the hole.

Just in case you find a classic WWII carbine, any of the makers of the era will be acceptable, although the days of using a $1,000 collectible to plink cans on Sunday are now over.
For the new makers, avoid the 1960's clone, it was a parts gun and not well done. The new makers are doing a much better job. The .30 US Carbine cartridge is about equal to a .357 Magnum at the business end, nothing to sneeze at. Don't believe any of the myths about how it wouldn't penetrate ChiCom clothing in Korea.
I'm partial to the wood and steel, myself, being theconservativegunowner that I am, the M1 carbine would be a very good choice for home defense and plinking. Another choice is the Ruger Mini-14 in blued or stainless steel. The cartridge is the 5.56mm, or .223 Remington, good choice.
An inexpensive carbine is the SKS, these have a fixed 10-round magazine and are well-made and reliable. Avoid the detachable mags, they really don't function too well. The cartridge is the 7.62x39 Russian, very good ballistics.
Whatever you choose, do stock up on magazines, stick with genuine GI US or ROK make, or Ruger factory mags, at least for a little while.
As an aside, any of the wood/steel carbines noted above can be turned into a 'tacticool' mall ninja special in about 15 minutes. The receiver and barrel are the moving parts and they remain exactly the same, the function is unchanged, only the appearance is different.
If you do a lot of plinking, the .30 Carbine round can cost you a bit of change, do look at a reloading setup if you're shooting more than a few hundred rounds a year, you'll save money over time.
All of the above are light for hunting anything larger than a coyote. For deer or larger game, look at a good used bolt rifle, you can find a lot of choices at local pawnshops or gun stores for well under $500, often in the $350 range.
You can get classic semi-auto rifles in hunting calibers, like the FN49 or similar, but you'll spend $1,000 and will not have a good choice for home defense, if that's limited to the front hallway. You could try a Browning BARII for a very nice semi-auto.
Do consider a shotgun for home defense, and a revolver or pistol for concealed carry and home defense. The times, they are a-changin'.
Welcome to Washington state! Nobody doesn't like it here, as they say.
