Thompson Sub-Machinegun


The TSMG, Thompson Submachine Gun, was ahead of its time.  Too late to serve in WW1, for which it was designed, it became symbolic of Chicagos' organized crime in the 1920's, the Public Enemies of the 1930's, and it took an under-prepared America to war in WW2. The Thompson served around the world with the Allies during the dark days of the early war period, all the way through to the Normandy Invasion and to the end of the war, even with its replacement, the M3 Grease Gun coming into service.

Due to U.S. Importation Laws, not only are receivers banned from import so too are barrels, so as time passes, original barrels will become increasingly scarce and valuable.

I manufacture, and sell, TSMG barrels for all purposes, DISPLAY, BLANKFIRING, and LIVE/FIRE, in all Thompson SMG model types. Please read below for the specifics.


The DISPLAY barrels are manufactured from chrome moly steel, 4140, to a rockwell of 26-32, as are the BLANKFIRE and LIVE/FIRE barrels. The DISPLAY barrels have no bore, nor chamber, and are blind drilled to .453" at the muzzle end, with the muzzle crowned. As these barrels have no bore, and are solid steel, they are classed as "NON-BARRELS" by BATFE, this is an important classification. Not only can a DISPLAY barrel be used to complete a parts kit, but, for the re-enactor who has a new production Auto Ordnance Thompson Carbine with the long barrel, by sustituting a DISPLAY barrel, classed as a "NON-BARREL", the re-enactor can achieve the correct look of the SMG, without the SBR issue. Once finished with re-enacting, the gun can be restored to firing capacity by re-installing the long carbine barrel. My DISPLAY barrels are significantly less expensive than an original, particularly when you consider the cost of a tax stamp the issues of a background check to obtain an authentic barrel with a bore.

I can provide a DISPLAY barrel either with receiver threads, for use with a quality reproduction steel receiver, or, unthreaded for use with the cast aluminum display receivers.


The BLANKFIRE BARRELS are classed as "NON-BARRELS" by BATFE, again, an important classification for the reasons stated above. They have no through passage, and are meant to be vented perpendicular to the axis of the 'non"-barrel, doing so maintains its NON-SBR status, as no projectile can pass from the chamber horizontally out through the muzzle. Because blankloadings vary, the BLANKFIRE barrel will need to be vented, in number of vents/size to the blankloading, heavy vs. light. Once this is done, the owner will have to continue to use the same type of blankload, for the bolt to cycle. The buyer, or gunsmith, will have to form the vents, and also the chamber. Why don't I form the chamber in the BLANKFIRE barrels? By my not doing so, the buyer/gunsmith is responsible should anyone ever chamber a live round in a blankfire barrel. I DO deep drill from the receiver end of the barrel to the correct size to use a TSMG chamber reamer to form the chamber, leaving solid steel between where the deep drill stops and the muzzle.


I purchase barrel blanks that are specifically made for the TSMG, chrome-moly steel, to a hardness of 26-32 rockwell, 1:16 RH twist rifling, and chambered to G.I. Specifications. From these barrelblanks, I turn the appropriate finned contour, 1921 with radius fins, 1928/A1 with square fins, or the basic M1/M1A1 non-finned barrel.

All of my barrels for whatever purpose, are polished and powder blasted prior to delivery to a professional hot black oxide service or as a NEW SEVICE for PROFESSIONAL HOT BLUEING. The LIVE FIRE barrels are inspected from the vendor for chamber tolerance, and for thread fit, prior to my machining the pattern type.



M1/M1A1 = $95

1928 ( square fins)  = $125

1921 ( radius fins )  = $155


M1/M1A1 = $115

1928 ( square fins ) = $145

1921 ( radius find ) = $175


M1/M1A1 = $145

1928 ( square fins) = $170

1921 ( radius fins ) = $195

1921 ( radius fins ) NEW PRODUCT PROFESSIONAL HOT BLUEING = $235

S&H NOT included, typically $15 for continental U.S., and while the DISPLAY and BLANKFIRE "NON-Barrels are exportable, the LIVE FIRE Barrels are not.

While I do not manufacture Ringsights or Compensators, I do market them to help my customer one stop shop.


* these are new production pressfit, and have no threads, this simplifies assembly in that vertical of the front sight is easily achieved.

Please note, while I do no gunsmithing, I do offer some basic services, such as:

-Threading the barrel muzzle for an original Compensator

-Driling a new Ringsight for a crosspin, and providing the pin

-Display Bolt Actuator handles-

-Assembling Display Only guns from your provided parts/kit.

Please ask for pricing on these services, as I discount the services if you buy parts from me.

Also, I have, and continue to do Custom Work, part manufacture, from providing "Prop-Gun" parts to the movie industry to small quantity specialty parts, obviously, as with anything I sell, all NFA Rules are observed. So, feel free to ask about my custom services, but, please understand, often jigs/fixtures must be made before work of this nature can be done to hold the part(s) so that machining can be performed, my price(s) reflect building any such fixtures.

Below, is an exmaple of  my custom work, a recent commission, a display receiver and barrel for the UD42 SMG.
