Troy’s .875 Low Profile Gas Block is made specifically for bull barrel rifles that have a 0.875 gas block seat and Armalite 0.308 heavy barrel and other calibers.
- The low-profile design allows for clearance of most aftermarket rails that require a smaller gas block
- Machined from 4140 pre-hardened steel finished with MIL-STD Manganese Phosphate
- Fits tightly to the barrel using two set screws
Gas tube roll pin not included.
