I'm on about 700 rounds with my new XCr Key-mod and really enjoy shooting the rifle. I love the fast stock..I have zero love for the AR style, not sure why the draw is there but then again the fast stock fits me like a glove and perhaps not with others.
As far as accuracy this rifle is no where near bolt gun accuracy, to expect that you will get one hole groups out of a semi-auto rifle is expecting a bit much. Accuracy claims on the net....id give them about 20% truth to them. Someone might luck out and get a .25 moa group then go and tell others their XCR is a tac driver..but they never can do this repeatedly.
I've owned the very first gen XCR's and now this Key-mod and its a completely different gun. Great machining,fit and finish, slim to hold, well balanced and 100% reliable with cheap MFS ammo. Trigger is OK and the open sights are pretty solid.
To the OP have you tried different ammo? Have you had a buddy watch your technique? Have you thoroughly went through your rifle and optic? We all like to blame the rifle when things dont all go into one hole but there are many other factors.
Cheers!!
