The Aim Sports Zero Hour Micro Gas Block (Aim Sports part no. ZHMGB01) is a low-profile gas block sized for .750-inch barrels, machined from 1018 steel and finished in black phosphate. Aim Sports keeps the profile low enough to clear most free-float handguards, so you’re not stuck choosing a handguard around the gas block instead of the other way around. It’s a straightforward way to finish a build or replace a bulkier factory block that’s been forcing a handguard compromise.
