What does pinning gas block mean?
The gas block on an AR type rifle must be carefully fitted to the barrel at the gas port and be securely attached so it won’t move and cause short cycling. The first and most critical step to pinning is to properly position the block on the barrel so the gas tap hole is directly over the barrel gas port.
