Auto-Ordnance Thompson M1 Carbine .45 ACP 16.5in 10+1
About this product
What is the Auto-Ordnance Thompson M1 Carbine .45 ACP 16.5in 10+1? It is a historically faithful semi-automatic reproduction of the classic .45 ACP Thompson submachine gun platform, engineered specifically to meet modern sporting rifle regulations while preserving iconic handling characteristics. This 16.5-inch barreled version maintains the overall silhouette and heft of the original, but its fixed stock and semi-automatic-only operation place it outside Title II/NFA regulation for transferable machine guns or short-barreled rifles. The 10+1 capacity stick magazine and blade-and-notch battle sights deliver the straightforward, robust functionality that made the design legendary, now configured for the modern collector and range shooter.
What is the Auto-Ordnance Thompson M1 Carbine .45 ACP used for?
This carbine is intended for historical re-enactment, collection, and controlled-range recreational shooting where its distinctive profile and .45 ACP chambering provide a tactile connection to mid-20th century small arms. It is not, and cannot legally be converted into, a fully automatic firearm; its primary function outside collecting is delivering low-recoil, close-range accuracy on steel targets at distances under 100 yards. For serious modern carbine training or practical shooting sports, a purpose-built platform like the Stevens 334 in .308 Win offers superior long-range ballistics and optic compatibility.
How does the Auto-Ordnance Thompson M1 Carbine compare to a standard USGI M1 Carbine?
The Auto-Ordnance Thompson is a substantially heavier and mechanically distinct platform firing a larger, slower pistol cartridge compared to the classic .30 Carbine M1. At 11.5 pounds unloaded, this Thompson replica is over 5 pounds heavier than a standard 6.25-pound M1 Carbine and fires the .45 ACP round, which generates roughly 35% more felt recoil impulse but travels at under 1000 feet per second, making it effective only to about 75 yards with iron sights. The Thompson wins on historical presence and close-quarters stability, while the M1 Carbine is objectively better for lightweight maneuverability and flatter trajectory out to 200 yards.
What does it weigh and what are the dimensions?
This carbine has an unloaded weight of 11.50 pounds (5220 grams), an overall length of 38.00 inches, and a 16.50-inch cold hammer-forged barrel. The vertical foregrip adds approximately 3.25 inches of front-end control surface, and the solid American walnut stock contributes significantly to the balance point being located roughly 8 inches forward of the trigger guard. These dimensions create a handling profile distinct from modern carbines, favoring deliberate, supported shooting from barricades or benches rather than rapid positional transitions.
Who is this NOT for?
This is a poor choice for shooters seeking a lightweight, modular, or optics-ready tactical rifle for dynamic training or competitive use. Its 11.5-pound weight, proprietary 10-round stick magazines, and lack of Picatinny rail mounting solutions preclude it from modern practical shooting disciplines. Furthermore, individuals hoping for a project firearm to SBR or modify heavily should note that cutting the barrel below 16 inches would immediately classify it as an NFA item requiring a $200 tax stamp and months of ATF paperwork—this is a collector's piece first.
What's in the box?
You receive the carbine itself, one 10-round stick magazine, and a basic cable lock. No optics, sling, cleaning kit, or additional magazines are included from the factory, a notable contrast to more modern offerings that often bundle essentials. You will need to source .45 ACP ammunition (typically 230-grain FMJ for reliable cycling), eye and ear protection, and a suitable cleaning rod of at least .45 caliber diameter to maintain the 16.5-inch barrel.
Is the Auto-Ordnance Thompson M1 Carbine worth it at $1518.99?
At $1518.99, this carbine commands a premium justified solely by its historical niche and specialized manufacturing, not by modern performance metrics. For the same budget, a shooter could purchase a high-end Stevens 555 Sporting O/U 12 Gauge and several cases of shells for clay sports. Therefore, its value is intrinsic: if you specifically require an authentic semi-auto Thompson replica for display and occasional range use, the price is market-typical. If you need a versatile, general-purpose firearm, allocate these funds elsewhere.

Pros & cons
What works
- Historic 11.5-pound heft and 38-inch length match the handling of the original platform within legal sporting rifle parameters.
- Authentic American walnut stock and foregrip—materials not found on budget replicas or polymer-stocked alternatives.
- Accepts original 20-round and 30-round stick magazines for historical display and potential use in unrestricted states.
- 16.5-inch cold hammer-forged barrel provides a solid foundation for the low-pressure .45 ACP round, promoting consistent accuracy.
Trade-offs
- No optics mounting solution—requires $150+ in gunsmithing to add even a simple Picatinny rail section.
- Proprietary 10-round magazine ships standard; additional magazines cost $45-65 each, significantly more than common AR or AK patterns.
- The 11.5-pound weight is over 5 pounds heavier than a modern 5.56 NATO carbine, fatiguing for extended offhand shooting sessions.
- Blued finish, while classic, offers less corrosion resistance than modern Cerakote or nitride treatments common on firearms in this price range.

Frequently asked questions
- Is it compatible with original Thompson M1928 or M1A1 magazines?
- Yes, it is designed to accept genuine WWII-era 20-round and 30-round Thompson stick magazines, as well as modern aftermarket reproductions from manufacturers like Kahr Arms. However, to comply with certain state capacity laws, this model ships with a 10-round magazine. Always verify your local regulations before using higher-capacity original magazines.
- Does it fit in a standard 42-inch rifle case?
- Barely. With an overall length of 38 inches, the carbine will fit diagonally in most 42-inch soft cases, but the vertical foregrip may press against the interior padding. For optimal protection, I recommend a hard case with a minimum internal length of 40 inches, such as a Plano All-Weather 42-inch model.
- How long does shipping to an FFL take?
- For in-stock items, processing and shipping typically takes 3-5 business days before the firearm is en route to your selected Federal Firearms License (FFL) holder. Transit time then depends on carrier; expect 2-7 additional business days. You must contact your FFL dealer in advance to provide your information and confirm they will accept the transfer.
- Can I mount an optic or a red dot sight?
- No, not without significant gunsmithing. The receiver is a closed-top, milled design with no integral rail provisions. The only factory sighting options are the blade front and fixed battle rear sights. Drilling and tapping for a side mount is possible but will cost $150-$300 from a specialist and permanently alter the firearm's collector value.
- Does this work with a standard .45 ACP suppressor?
- Potentially, but the barrel is not threaded from the factory. To attach a suppressor, the barrel must be professionally threaded to 0.578x28 TPI or another common .45 caliber pattern, which involves removing the barrel from the receiver—a job for a competent gunsmith costing around $200. You must also file a Form 4 with the ATF for the suppressor itself.
