Low Profile Stainless Steel .750 Gas Block For Better Heat Dissipation

The AT3™ Low Profile Stainless Steel Gas Block features a minimized small bore design that perfectly works with our free-floating handguards. It is designed to fit all .750 diameter barrels and promotes a professional build structure to the rifle to eliminate the front sight on flat top rifles.

This gas block is constructed from durable 416 stainless steel which makes it a better option than aluminum gas blocks to withstand extreme temperatures.

Improved Seal & Better Heat Dissipation

The AT3™ Low Profile Stainless Steel Gas Block also provides full coverage around the gas port providing an improved seal and better heat dissipation. It includes 2 set screws to make sure it stays intact and is designed with a chambered roll pin hole for easy assembly.

Note: We recommend the use of Loc-Tite on each set screw to ensure your gas system will stay secure during use.

Basic Gas Block

Works fine, nothing remarkable outside of a glossy/polished finish. Not as shiny as a TiN bcg. It does paint well however.
