I just picked up a new DPMS Panther .223. I added a 7" quad rail and am now looking for a good tactical scope. I put a Leupold scope on it, but it got in the way of the charging handle. I am not wanting to shoot 400 yards, maybe up to 200 yards max. I am also looking for CQ shooting also. I found a 2.5 x 9 x 40 with Burris FastFire at Valhalla Armory. I was wondering if anyone has heard of them and if this scope would work for what I want. I appreciate any help I could get.
