BM4robbins Posted December 30, 2010 Share Posted December 30, 2010 I was visiting this site, and don't get item number 3 from the parts count list. http://www.carriercomp.com/FAQ.html How is there a barrel extension on an M4? The site says it is permanently attached and not recognized by atf. All I see on the m4 I lloked at is a choke which IS removable. Confused.

BM4robbins Posted December 30, 2010 Author Share Posted December 30, 2010 I even asked this ? on a different forum ar15.com I think a few months ago when I first read this page and the people on that forum drew a blank.

KB Fab Posted January 2, 2011 Share Posted January 2, 2011 Muzzle break. Number 5 actually covers that. The way I read #3, the one the OP is referring to, is that it pertains to some type of permanent attachment for breaching. Quote Link to comment Share on other sites More sharing options...
saym14 Posted January 2, 2011 Share Posted January 2, 2011 I beleive the list of parts is from a generic BATF list of gun parts. those with the red asterick such as item 3 are noted as not pertaiing to the Benelli M4. Quote Link to comment Share on other sites More sharing options...
Guest cleefurd Posted January 2, 2011 Share Posted January 2, 2011 (edited) This is an example of an AR15's barrel extension (922r line item #3.), attached to the breech end of a barrel, and often confused with an item defined as a muzzle attachment. Both are extensions of a barrel, but appied on opposite ends. The M4's extension (portion hidden within receiver when inserted) is permanently attached, and not on the list (knock on wood) Edited January 2, 2011 by cleefurd Quote Link to comment Share on other sites More sharing options...
uscm Posted January 2, 2011 Share Posted January 2, 2011 So, based on the various lists I've seen, a combination of 3 of the following commonly available US made parts are what people should be looking for in order to be 922r compliant: • Buttstock (with integral pistol grip) • Forearms / handguards •*Full length magazine tubes • Magazine tube follower Quote Link to comment Share on other sites More sharing options...
