Proudly Made in USA. The monolithic top rail of the handguard sits directly against the upper receiver rail. M-LOK attachment points are located at the 3, 6 and 9 o’clock positions. The slim 1.25″ inner diameter will require a slim muzzle device. This includes our “Slim” Flash can if applicable.
Weight comes in at 7.2oz for the rail itself. The rail, steel barrel nut and attaching screws brings the weight to 10.6oz. The barrel nut will accept a 1 3/16″ or (30mm) wrench or crow foot. Quick Detach Mounts are built into the handguard at the rear position.
Installation should be complete by a gunsmith. The barrel nut must be torqued to a minimum of 38 FOOT LBS. The (2) handguard screws should be torqued evenly to 40 INCH LBS with blue removeable loctite applied.

Proudly Made In The USA. “SQUADRON” quad rail with lightweight cuts make it feel as it it’s floating on air. It is machined from 6061 aluminum and anodized with a Type III Class 2 Hardcoat. The rail itself weighs in at 8 oz. Add the barrel nut and attaching screws for a total of 10 oz. The top rail sits directly against the upper receiver rail while anti-rotations tabs at the sides assist to prevent any movement. The inner diameter is 1.8″ which will allow most suppressors to fit inside the handguard. Quick Detach Mounts are built into the handguard at the front and rear positions.
