Key Features
- Bullpup Design – Why it matters: You get a full 18.5-inch barrel in a shotgun that measures just 28.5 inches overall. That means easier handling in tight hallways and doorways without sacrificing shot spread or velocity.
- Gas-Operated Semi-Auto Action – Why it matters: Reduces felt recoil and cycles low-brass target loads reliably. You can shoot all day at the range and stay on target for follow-up shots.
- Threaded Barrel – Why it matters: Accepts standard choke tubes so you can tailor the pattern for buckshot, slugs, or birdshot. Versatility for home defense or range use.
- O.D. Green Cerakote Finish – Why it matters: This finish resists corrosion, scratches, and wear. It also blends in with outdoor settings if you ever take it afield.
- Flip-Up Sights and Picatinny Rails – Why it matters: Comes ready with iron sights out of the box. The top and bottom rails let you mount a red dot, light, or laser without gunsmithing.
Who It’s For
This shotgun is built for the southern shooter who wants a compact, maneuverable home-defense tool that still packs a 12-gauge punch. It’s also a great fit for truck guns, range toys, or anyone who appreciates the bullpup layout for close-quarters work. If you like to accessorize with lights and optics, the rails make it easy.
Pros & Cons
- Pros: Compact length, full barrel performance, low recoil, accepts common AR-12 magazines, Cerakote finish, and affordable price point.
- Cons: The trigger pull is heavier and less crisp than a traditional shotgun—common with bullpup designs. Also, the loading port can be a bit tight for gloved hands.

What magazines does it use?
It accepts AR-12 pattern magazines and drums. These are widely available from multiple manufacturers.
Is it legal in all states?

Can I mount a red dot or light?
