After taking the barrel off I re-tightened it to 200 inch/pounds. I took it to the range. I sighted the rifle in at 25m. I then went to the 100 meter firing point. The rifle is shooting 4 inches high but is now centered on the paper. Correct me if I wrong, but if a rifle is sighted in for 25m it should shoot an inch high at 100m. (I am basing this off my Ar15). The XCR sights are higher from the barrel then the ar15s. Does it naturally shoot 4 inches higher between the 25m and 100m?
