Our seven sided Keymod handguard is built to handle the hardest use and abuse of tactical and competitive shooting while offering more versatility than other handguards. It features a full-length picatinny top rail that sits flush with M4 flat top receivers allowing you to have more space for optics and back up iron sights.

This AR-15 handguard is machined from 6061 aluminum, has a hard coat anodized black finish, and comes with a proprietary barrel nut and mounting hardware.
The barrel is one of the few components that directly affect the accuracy and weight of your build. This barrel has a nitride finish for increased strength and durability.
