🛠️ Description:

Offered here is a Cobray MOD. U/D ("Upper/Down") Pistol Kit, a rare 80% complete double-barrel build kit from one of the most iconic American gunmakers of the 1980s-1990s.

This compact, break-action pistol features over/under barrels and is chambered for both .45 Long Colt and .410 shotgun shells. Originally sold as a DIY kit, the MOD.

This kit includes most major parts and is ideal for collectors, machinists, or builders looking to restore a unique and discontinued design. It is not functional as sold and will require fitting, fabrication, and finishing.

🏛️ About Cobray & the MOD. U/D:

Cobray was known for producing affordable, bold firearms like the MAC-11, Street Sweeper, and other iconic designs that earned them a cult following. In addition to full firearms, they also sold DIY kits to the civilian market, like the MOD. U/D.

The MOD. U/D (short for "Upper/Down") stands out as a compact over/under double-barrel pistol, chambered in .45LC and .410—perfect for survival use or as a powerful backcountry sidearm. Its break-action design and dual-barrel setup made it a favorite among collectors of oddball or outlaw-era firearms.

These kits were never mass-produced in large numbers and are extremely hard to find today, especially in unassembled condition. This is a great opportunity to own a part of Cobray’s unique legacy.
