Frequently Asked Questions

What does ‘low-profile’ mean? A low-profile gas block sits below the handguard’s inner diameter, letting a free-float handguard slide over it rather than requiring a cutout.

Will this fit any barrel? It’s sized for a .750-inch barrel journal; measure your barrel’s gas block journal diameter before ordering to confirm fit.

Is gunsmithing required to install it? Installing a gas block typically requires removing the handguard and, on some builds, the front sight base or barrel nut; a gunsmith can install it if you’re not experienced with this kind of work.
