Basically, you can have a 9mm AR that uses Glock mags with a full length key mod rail for $700. Way under most other companies AR style offerings.
Tidbits;
Hand guard rail mount is rock solid. Bolt is a one piece unit. Very easy to clean. Firing pin is spring loaded. Trigger is about 7lb. Could be better. Might get lighter with more use. If not, an easy fix. Unlike the Colt mag lower, the bolt does not lock open after the last round. I can live with that. My Just right carbine was that way, as well as my 10/22s.
Took it to indoor range to sight in the sights and red dot. Only put 120 rounds through it, but no problems. 80 fmj, 40 wide mouth hollow points. I plan on taking out again this weekend.
The only problem with these, is catching them in stock. You have to sign up for the email alert. And you need to act quick.
