The APR is slick. It really depends on the ranges your shooting. The APC is just as accurate but your going to give up some velocity. If I remember correctly FGMM 7.62M2 does about 2550 from the 16” guns. They are plenty capable to 800yds and can be pushed farther. KAC is releasing a 22” 6.5 Creedmoor upper as well. I’m not sure when they will be available though. Give Jacob Nakley a call at NS Defense and he can get you squared away. Good guy to deal with.
