The King Arms Nylon M4 RAS II connects directly to the upper receiver of the gun to free float ,enhancing accuracy and rigidity of the gun. The addition of the Crane stock allows more accessory mounting surfaces on the gun, giving the user greater versatility.

The King Arms RAS II is truly for those who desire the Spec Op look.
