Key Features

• 7.5″ Threaded Barrel with 1:8 Twist — WHY IT MATTERS: The 1:8 twist rate stabilizes both 220-grain subsonic and 125-grain supersonic loads, so you can run suppressed for deer or plink with cheap ammo. The threaded muzzle lets you attach a suppressor or muzzle brake without a gunsmith.
• SBA3 Pistol Brace — WHY IT MATTERS: This adjustable brace gives you a stable cheek weld without the hassle of a tax stamp, making it legal to carry in a pack or truck while still offering a solid shooting platform.
• Flat Dark Earth Cerakote Finish — WHY IT MATTERS: Cerakote resists rust, scratches, and the humidity of a southern swamp hunt. The FDE color blends into dry brush and cutover fields better than black.
• 7″ M-LOK Handguard — WHY IT MATTERS: You can mount a light for feral hogs at night or a bipod for coyotes without adding much weight. The slim profile keeps your grip comfortable.
• Includes 30-Round Magazine and Canvas Carry Bag — WHY IT MATTERS: You get everything you need to start shooting right out of the box. The bag protects the pistol during transport to the lease or range.

Who It’s For

This pistol is for the southern shooter who wants a compact, packable .300 BLK for suppressed hunting or truck-gun duty. It fits the guy who already has a 16-inch AR but needs a shorter rig for brush hunting hogs or walking a timber road after doves. It’s also a solid choice for the reloader who wants to experiment with subsonic loads without building a whole new gun.

Pros and Cons

• Pro: Compact 7.5-inch barrel makes it easy to maneuver in thick cover or inside a vehicle.
• Pro: Threaded barrel and SBA3 brace let you run a suppressor legally without a tax stamp.
• Pro: Flat Dark Earth Cerakote is tough and reduces glare.
• Con: A 7.5-inch barrel limits muzzle velocity with supersonic loads compared to a 16-inch carbine, so you lose about 200 fps on 125-grain ammo. That’s fine for close-range hogs but not ideal for long shots.

FAQ

Does this ship with a brace or a stock?

It ships with an SBA3 pistol brace, not a stock. This keeps it classified as a pistol under federal law, so you don’t need a tax stamp for the brace.

Can I use supersonic ammo in this 7.5-inch barrel?

Yes, but you’ll get lower muzzle velocity compared to a longer barrel. The 1:8 twist handles 125-grain supersonic loads fine, but expect around 2,200 fps instead of 2,400 fps from a 16-inch barrel. It’s still lethal on hogs inside 150 yards.

What suppressor works best with this gun?

Any .30-caliber suppressor with a 5/8-24 thread pattern will fit the barrel. A lightweight can like the SilencerCo Omega 300 keeps the rig handy for walks in the woods.

Does it come with a case?

Yes, it includes a canvas carry bag for storage and transport.
