The inner workings are handled by a quality, mil-spec CMMG lower parts kit with a crisp, single-stage trigger. Out back, you’ll enjoy a classic six-position M4 buttstock paired with a .308-specific short buffer and spring.

Fantastic quality kits. This is the second one I have purchased.
Ron Hendrix –
Everything seems good! Easy purchase! Fast shipping, wish finish and deburring was better. But still great value.
Glenn Swan –

Gary Vanderhill –
Great upper just waiting for website to open up to get the lower
Bro david –
Better than expected. SS barrel is sweet. Shoots awesome. Mounted to my ATV . Converted to full auto and placed a suppressor on it. Nightforce scope with nightvision. Auto sear included free. Just kidding. Great gun
Daniel Torres –
I like this so far although I haven’t had any range time yet. I only gave it a 4 star review because it was packed poorly with a second kit for an AR15. The box was crushed and there was a lot of excess space that allowed everything to bounce around inside.

Fun, learning experience!
