[ARCHIVED THREAD] - Bolt Carrier Group Question

Posted: 10/15/2008 2:51:24 PM EDT

I'm getting ready to build up an AR pistol based on
a Rock River complete pistol lower receiver assembly.

Is there anything special I need to know about when
looking for a bolt carrier group for a 7.5" barreled
upper?

I did see that LMT lists most of their BCGs as needing
a minimum 14.5" barrel.

Also any recommendations on manufacturers and
places to look for a quality BCG?

I've run a full auto stag/cmt in mine without hardly a hitch...it's all about timing and weight...which directly reflects back to what kind of spring/buffer/bcg you may be using at the time. See what RRA suggest's and go from there, I was lucky enough to have several different set's of parts laying around that I could play with to try to determine the best set up for mine.

I run M16 BCG's in all of ours.

m16 BCG ? not the civi ar-15 BCG ?
i was under the impression that any full auto part in an AR rifle/pistol would be a big no-no in the eyes of the batf for those of us non-nfa / class III . ( correct me if im wrong ) the reason i bring this up is i have a pistol upper on order from ya'll and am not wanting any parts which would cause conflict with my schedule over the next 10 years ...

Its ok to run the M16 BCG but no other parts.

i'll e-mail ya'll about the order, i'd rather have the AR type BCG, not the m16 BCG. im not positive about the law, so i'd rather play it safe.

+1...nothing in the lower can be M16
