Genesis Arms GEN-12 Shotgun Rifle - 18.25" Threaded



This is a revision of their Signature Model.  It has upgrades which include a longer Mlok rail, and other enhancements increasing accuracy and durability.


It features a collapsible stock, right side charging handle, and a free float rail with Mlock at the 3, , and 9 o'clock position.  The lower is modeled after the DPMS GEN1 308 pattern, and is outfitted with a standard A2 style grip.  It is also fully functional with any GEN1 308 patterned upper.  The GEN-12 comes standard with a 5 round magazine.

There is no gas system to tune, operating on a standard DPMS short carbine buffer/spring recoil system, the GEN-12 will reliably feed 2 3/4" and 3" 12 guage shells so long as they stack in the magazine.
