ERGO Adjustable Gas Block (0.75")

The Ergo .750" Adjustable Gas Block is designed to fit under the Ergo Modular and SuperLite Rail System, as well as most other manufacturer’s free-float handguards. The gas block allows the user to variably fine tune their rifle’s gas system down to full shutoff.

Adjustments are made via a 10-32 set-screw and a 4-40 brass retaining screw ensures the system remains locked, no need for Locktite.

Melonite QPQ finish for durability, and machined from 4140 chromoly steel with chamfered edges, featuring a slip on fit for ease of installation and secured with two set screws. Retains the same height/profile as the standard Ergo low profile gas block.
