Ordering Your Gas System is Easy...
- First, determine the barrel diameter at the gas port. We have it listed in the barrel descriptions. Order a gas block of the same diameter..
- Second, determine the length of your gas tube. We have it listed in the barrel descriptions: Carbine length, Rifle length, etc.
- Refinements, we have basic gas blocks and we have adjustable gas blocks. Our barrels are designed to work fine with either type... Remember that. You can always start with something basic and add refinements later.
