The Troy .875 Low-Profile Gas Block is for bull barrel rifles with a 0.875 gas block seat. That includes the Armalite .308 heavy barrel and other calibers with the same seat size, so it's the block to look at if your rifle has a heavier barrel profile.
It's machined from 4140 pre-hardened steel and finished in MIL-STD manganese phosphate, and it weighs just 0.05 lbs. The gas tube roll pin isn't included, so order that separately if you need one. Check that your barrel has a 0.875 gas block seat before ordering.
