AR10 build

Proof Research carbon fiber 308 barrel 16", Rifle Speed adjustable gas block (maybe my favorite adjustable gas block yet) we have Noveski switchblocks, Seekins precision, and Strike Industries versions of adjustable gas blocks.. to test and compare in near future. All that we are waiting on is the SLR Rifleworks upper/lower set with handguard Cerakoted In their "Fighter Cam" going to be a bad a$$ Ar10. #ar10 #slrrifleworks #proofresearch #riflespeed #adjustablegasblock #carbonfiberbarrel #308
