Shoots good

by -

This trigger is about what you can expect in rifle of this class. It breaks gravely at just a little over 5 lbs consistently. I replaced the trigger. Mine came with a magazine contrary to expectations.
Recoil is relatively light as you would expect from an AR15 class rifle.
On thing I didn't like about this rifle is that the Primary Arms forearm feels rather course. Like the machined lightening holes weren't deburred properly. Not enough to cut a hand, just rough. And I would prefer something other than M-lok again, Q-lok would be better.
Shoots Hornady Black 110 grain in 3/4 or less groups at 50 yards and I am not that great a shot. Hornady 190 grain subsonics even tighter.
