Key Features
- Salt Bath Coated BCG — This coating reduces friction and resists carbon fouling, meaning your rifle stays cleaner longer and runs smoother during range sessions with the family.
- 4150V Chromoly Barrel — A mil-spec steel alloy that handles the higher pressures of .300 Blackout without premature wear, giving you consistent accuracy shot after shot.
- M-Lok Handguard — Lets you attach lights, grips, or bipods exactly where you need them, keeping the rifle balanced and easy for smaller shooters to handle.
- Enhanced G.I. Sopmod Stock — Provides a secure cheek weld and six-position adjustability, so it fits both dad and the teenager learning to shoot.
- Non-Adjustable Gas Block — Simple, reliable, and maintenance-free — no tuning needed, just load and shoot.
Who It’s For
This rifle is for families who want a dedicated .300 Blackout platform for home defense, hog hunting, or suppressed shooting. It’s beginner-friendly because the direct impingement system is proven and easy to clean. It’s also for shooters who appreciate a no-frills, mil-spec build that doesn’t require upgrades out of the box.
Pros / Cons
- Pro: Salt bath BCG reduces cleaning time — a real plus for busy parents.
- Pro: 30+1 magazine capacity gives you plenty of rounds for practice or defense.
- Con: The non-adjustable gas block means you can’t tune it for suppressed vs. unsuppressed use — you’ll need to choose one or use a dedicated suppressor-rated buffer.

FAQ
Can I use this rifle for home defense?

Yes, it includes a flash hider from the factory. If you plan to add a suppressor, you may want to swap it for a compatible muzzle brake or direct-thread adapter.
