Ok my fellow Airsofters. I'm looking for a part, boneyard gun or whole gun (not to $$$). I have an King Arms Sig 556 Shorty and looking for a part. I don’t know the name of the part but I can send a picture of it. The buffer tube attaches to it. The one I have has a broken tab. If you have it please contact me. If you have a incomplete one KA/Cybergun and want to sale it contact me or a whole one contact me.
