Frequently Asked Questions

Does this kit include a lower receiver?

No — this is a complete rifle kit minus the 80% lower. Everything above the lower receiver — the assembled upper, barrel, handguard, bolt carrier group, charging handle, and muzzle device — is included, so you’ll need to supply or purchase your own lower separately.

What makes the window-cut M-LOK handguard different from a standard M-LOK rail?

The window cutouts remove extra aluminum between the M-LOK slots, shaving weight off the handguard without sacrificing rigidity or the number of usable mounting slots. It’s a lighter-weight option than a solid M-LOK rail while still accepting the same M-LOK accessories.

What’s the barrel spec on this kit?

The upper ships with a 16-inch chrome moly barrel with a nitride finish and a 1:7 twist rate, running on a carbine-length gas system with a .750″ gas block — a standard, reliable setup for 5.56/.223 ammunition including heavier bullet weights.

Does the kit include a bolt carrier group and charging handle?

Yes — a bolt carrier group and charging handle are included standard with this kit, along with the muzzle device. All you need to add is a lower parts kit and stock once you have a lower receiver to complete the build.

Does this kit come with a muzzle device?

Yes, a muzzle device is preinstalled on the 1/2″-28 threaded barrel. If you’d rather run a different flash hider, brake, or suppressor mount, you can swap it out since it’s a standard-thread attachment.
