Troy AR-15 Gas Block .750 Low-Profile - SGAS-A4L-00BT-00

The Troy 0.750 Low-Profile Gas Block is made specifically for rifle barrels that have a 0.750 gas block seat. The low-profile design allows for clearance of most aftermarket rails that require a smaller gas block. The low-profile gas block fits tightly to the barrel using two set screws. Gas tube roll pin not included.
