Does this bolt require a special barrel extension, or will it work with the standard AR15 barrel extension? I ask because a while back there was a super bolt advertised that worked in conjunction with it's special barrel extension. The super bolt and barrel extension units that I'm referring to were very impressive, and I didn't know if yours was a "standard" sized bolt, or the oversized one that uses a different barrel extension.
