[QUOTE="budlight, post: 3088834, member: 2939"] The original m-16 had a 14:1 twist rate and a 20 inch barrel. Who ever made the chrome lines 7 twist 20 inch that I bought probably should have stayed in school! If I bought off the sheft slower 55 gr fmj it might have been fine. Because slower velocity made it not key hole the paper. Or if I shot slower heavy bullets it worked. I just will never buy another 7 twist [/QUOTE]
