Been looking around and can't really seem to find one. I am interested in getting a monolithic upper for my pistol build but I want to get one the right size so that the rail reaches just to the start of the muzzle break. Many of the measurements for these are C. O. P. length designations and I can't seem to find a conversion for them. I was wondering if someone had a chart or knew the conversion ranges.
Thanks. |
