Auto-Ordnance has introduced a special-edition, semi-automatic Thompson M1 carbine customized by Altered Arsenal to commemorate the 250th anniversary of the United States Marine Corps. The guns wear a Cerakote two-tone receiver, with a matte black upper and a contrasting white lower. The left side is emblazoned with the name “MARINES” applied in a durable and vibrant USMC Red Cerakote finish.
On the right side they feature elegant engravings of “250TH ANNIVERSARY” and a commemorative crest. In a unique tribute, the top of the receiver is adorned with a custom design of red and gold that evokes the iconic Marine Corps Dress Blue uniform.
The firearm is fitted with custom wood furniture, with each piece detailed with historical battle scenes. The wood fore grip is engraved with “U.S.” and “250 Years of Service” on the buttstock. Each gun is chambered in .45 ACP, with one 20- and one 30-round stick magazine included.

Navy Commemorative Thompson M1 Carbine
Auto-Ordnance is also honoring the unwavering spirit of the U.S. Navy with a commemorative Thompson semi-automatic carbine. This special-edition piece, detailed by Altered Arsenal, is a tribute to those who have served and continue to serve at sea.
Featuring an all-white Cerakote finish across its barrel and receiver, it evokes the clean lines of a naval uniform. The classic wood furniture provides a rich contrast. The left side of the receiver proudly displays “NAVY” in bold lettering and the right side wears “250TH ANNIVERSARY” engravings and a commemorative crest. The top of the receiver bears a black-and-gold pattern, a nod to the gold braid and buttons on Navy dress uniforms.
The fore grip is engraved with “U.S.” flanked by patriotic stars. The dark, richly textured stock is adorned with a pattern incorporating the “250 Years of Service” commemoration, and historic battle scenes. Anchors adorn the wood grip. Each gun is chambered in .45 ACP, and comes with one 20- and one 30-round magazine.
