    Have you ever seen one run hard ??

    I have friends (me too) that have Colt Sporter A2 rifles with the cut bolt carrier, sear block, wrong size trigger and hammer pins, wrong size take down pin, etc. A couple have owned these for over 20 years and have fired them a lot with absolutly no problems. I understand that the sear block limits your after market trigger options and I have read here all about bolt carriers. I also realize that with the A2 configuration you are limited on the height that optics will set. I get all of this.

    My question is: Has anyone here ever seen one of this era of Colt rifles run HARD ?? I mean hard as in a carbine course or such. If so, how did they hold up? I would think just fine. Because after you get over the annoyance's that I listed that were done to these rifles...........the only thing that I see different in regards to how they would perform is that one has a cut bolt carrier and the other's do not. What do you think ??

    spank the trigger on that thing like a wild pony and don't worry about it. It will be fine and will perform just as well. I've seen plenty of old school guns run in classes from Air Force units that still have a lot of these "retro's" All had the happy switch also---

    Yeah, the vast majority of the USAF's M16A2's are converted early-mid 60's era Colts (M16s, pre-A1). They are still going strong...

    I have a 6530 lower that I intend to send off to ADCO one day to remove the homo-erotic sear block and install the proper pivot pin.

    I want to be able to run a M16 BCG so the block has to go. I haven't had any issues to date with this carbine as is but it is annoying dealing with the PC faggotry.

    I just cut my sear block off with a dremel.

    They'll run fine. It's when you start mixing those parts with out of spec uppers (over gassed) or lower parts from crappy manufacturers that you get problems.

    I do not know of any M16's with the wrong size pins, sear block, and notched hammer and carrier in US service.

    The notched carrier will destroy firing pins and FP retaining pins, I don't know of any other issues besides spare part availability being less than standard parts.

    Thanks so much for the info. When you say notched carrier are you talking about the back bottom of it being cut off (half moon) or the way it is cut where the back of the firing pin protrudes and is not as protected ??

    It's the ramped part by the firing pin collar. I still run a few of those Colt Carriers on longer gas systems since those guns run smoother... and I don't have any problems with firing pin or retaining pin damage.

    Years ago it used to be really bad when guys would mix those carriers wtih DPMS LPKs which were all kinds of out of spec.

    I'd send it off to Ken Elmore and he can remove the block and allow you to use a standard fcg and bcg.
