An AR-10 gas block is a component that regulates the flow of gas from the barrel to cycle the action in AR-10 rifles chambered in .308 Winchester or 7.62×51 NATO. It fits over the barrel’s gas port and connects to the gas tube, directing gas back to the bolt carrier group for reliable cycling. The AR-10 gas block works with AR-10 barrels (with the correct gas port size), gas tubes, upper receivers, handguards, and bolt carrier groups, making it essential for proper rifle function and customization.
