An AR-15 low profile gas block is a compact gas block designed to fit under free-floating hand guards, providing a sleek profile while directing gas from the barrel to cycle the action. It replaces the standard, bulkier front sight gas block. The low profile gas block works with AR-15 barrels (with a gas port), compatible gas tubes (carbine, mid, or rifle length), upper receivers, hand guards, and bolt carrier groups. It’s ideal for custom builds, allowing for more accessory options and improved aesthetics.
