A low-profile AR-15 gas block sized for a .750" barrel journal. The micro profile sits under a free-float handguard and ships with the roll pin needed to retain the gas tube.

Features:

• Low/micro-profile AR-15 gas block
• .750" journal diameter
• Roll pin included
• Designed to clear a free-float handguard

For .750" barrels only; it will not fit .625" or .875" journals. It is not intended for use under FSB-height handguards. A dimpled or pinned barrel provides the most secure installation.
