My friend has one of these on his Classic Army M16A4, and let me tell ya, he let me borrow one of these for my CA M4, and I never missed a shot, and later when I got tired of running around, I hopped in a tree and sniped with this! NICE JOB WHOEVER MANUFACTURES THIS!
Only problem-Call Of Duty- like if you put it on an M16 that's 3rnd burst like my friend's. OMG get this if you want a sniper assault rifle.
