AR10 chambered in 308 16 inch stainless steel Proof Research barrel mated with a JP high pressure bolt, properly broke in and only shot about 40 rounds through it, I hate to sell but I need cash for bills. Custom cerakote camo job, new gas tube and adjustable gas block, I took my suppressor off and it will need the muzzle break tightened on. $1500 call or text 2087166921
