Hello all. I'm about to order some parts from CMMG and would like to know about their overall quality and performance. I really like what I see regarding features. My questions are; 1. Are the bolts shot peened and MPI tested? Some are MPI 2. Do the uppers have the M-4 cuts made into the forgings or are they dremel cut? Machined into the forgings 3. Type of accuracy I could expect from a 16inch M-4 1/7 twis tbarrel with M-193 or 60 grain TAP ammo. Very acceptable 4. Overall fit, finish and function. Great Thanks a lot guys. PJ  |
