Aim Sports ZHMGB01 Zero Hour Micro Gas Block .750" Low Profile

The Aim Sports ZHMGB01 Zero Hour Micro Gas Block is a compact, low profile gas block designed for AR-15 pattern rifles with a .750" barrel diameter at the gas port. Part of Aim Sports' Zero Hour line of AR components, this micro gas block delivers dependable gas regulation while keeping a clean, snag-free profile.

Machined from 1018 steel and finished in a corrosion-resistant black phosphate coating, the ZHMGB01 is built to handle the heat and carbon exposure of regular AR-15 use. The low-mass design sits tucked close to the barrel, giving end users a cleaner sight picture and a simpler handguard and optic mounting setup.

Designed as a direct-fit component for AR-pattern platforms with a .750" barrel journal, the Zero Hour Micro Gas Block is an excellent choice for new builds, handguard upgrades, or replacing an existing fixed sight-base gas block.
