Our objective is to build your AR 15 and AR 10 with Mentium handguards and M Lok rails at a fraction of the cost you would pay for big brand handguard, without quality compromise. Our M-LOK and KeyMod handguards use standard 1913 picatinny accessory rails allowing you to attach your favorite accessories. The free float handguards are from 7” to 15” in length, in black color and flat dark earth color from Cerakote's Elite Series,the most extreme performance thin film coating.
