MAS Defense 12.62" M-LOK Free Float
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 9oz for the rail itself. The rail, steel barrel nut and attaching screws brings the weight to 12.4oz. 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 front and rear positions.
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.
