Came today as promised. Yeah-h-h-h-h.
Ran down stairs, but before I could work on it, I had to finish installing the extended safety in my 1911. See story,
http://www.downrange.tv/forum/index.php?topic=8084.0Okay that done. Follow instructions.
First understand I got the National Match RRA trigger. It's their cheapest at $120. Now, and I forget sometimes, remember that "National Match" refers to a particular type of NRA competition, it doesn't mean "nationally acclaimed" "super match grade". Think of National Match as kinda of a production grade for ARs. There are limits to the modifications you can make and still shoot NM. So this isn't, and they weren't trying to fool anybody, the top of the line trigger. My thinking though is that most anything would be better than the trigger that came with my Eagle Arms AR. And I'm accumulating the parts to build up my own lower. I want one NM qualifying gun and one really accurate varmint grade one when I'm done.
So, I remove the old trigger and hammer, watching out for anything that might go "sprong!!!". Also paying attention to the way the pins were oriented. I don't have an AR-15 gunsmith block, but I do keep some various sized block of wood on my work bench. This help tremendously. It is so much better to have your work "secure" rather than trying to do it in your lap. This isn't a "drop in" like a Timney, so you have to hold the trigger in place while you run in the pin. Using a size smaller punch to hold the trigger against its spring helps.
RRA provides two replacement, over-sized pins. I used my originals as the over size were taking too much work to get in place. I don't detect any slop and have put the RRA pins aside if I need them later.
Installed the hammer using the same technique and then cycle the trigger/hammer about 40 times. All check out. Re-installed the upper and again, all check out. RRA details several safety tests which I ran and am satisfies it works well. Though just to be sure I'll only load 2 rounds in the magazines at first. There are no adjustments......or conversely, there's little to go wrong with it.
Feels great. It is a two stage and the first stage isn't very long, just right. The break is clean and crisp with no trace of creep. Feel almost like my Tikka T3 trigger which always gets oh's and ah's when I let people try it at the range.
I'll let you know how it shoots.
