Old Testament Firearms proves, yet again, that you don't have to spend an arm and a leg to buy a high-quality handguard that will handle everything from competition shooting, carbine-class training, law enforcement training, whitetail hunting or the standard range day plinking with friends.

Heck, even looks great sittin' in the safe on your safe queen!

Our MTR or "Milled Top Rail" Free Float Handguards offer the same exceptional quality, fit and finish that our Mod-1 and Mod-2 Handguards off with a pleasing aesthetic of the milled top rail. It offers a smooth transition from your upper receiver to the handguard with comfortable hand placement along the handguard and a transition back to picatinny rail at the muzzle end for BUIS attachment.

As always - The Mod-3 MTR Handguard's are Made In The USA and Offer Our Lifetime Guarantee!
