COMPATIBILITY NOTICE: Some 3rd party skeletonized upper receivers have the bore surface compromised that the bolt carrier slides on. 2A Armament does not recommend the use of these upper receivers due to a non-continuous slide surface that can cause binding and cycling related issues. 2A Armament cannot guarantee flawless fit and function in a 3rd party skeletonized upper receiver.
