.625 AR-15 Gas Blocks

58 products · page 1 of 2

A .625-inch gas block fits pencil and lightweight AR-15 barrels, whose gas block journal is slimmer than the usual .750. These gas blocks all have a .625 bore, mostly low-profile designs for free-float handguards. Measure your barrel's journal or check its listing first: a .750 block won't seal on a .625 journal.
