@Anberoka already posted up some great Maten info pics, but here are some more for y’all....
Pictured with Mega Gator forged AR15 lower for size comparison
The threaded bolt catch hole is nice because I HATE installing roll pins!
The Maten lower uses standard AR15 lower parts. It came with rear takedown and from pivot pins already installed. The rear takedown detent and spring are installed through a hole in the bottom of the receiver and held in place by a threaded set screw instead of being inserted from the back and held in by a rear plate like on an AR15
