I am in the planning stages of building up an AR15 Carbine.  While this rifle will most likely be used at close to medium ranges and not exactly be used for target or sniper duties, I still want it to be as accuracy capable as possible yet still tough enough for tactical/practical use.  I want the best trigger possible on this gun but it has to be durable on the long term.  This gun will be built on a Bushmaster lower receiver.  Is the stock Bushmaster trigger good enough?  I am very interested in the various two-stage triggers on the market.  I have a two-stage in my M1A that is sweet.  Are there any good two-stage triggers for ARs that will tough it out?  I have heard that some are a bit fragile and won't last very long with use.  Basically, if you are happy with a stock Bushmaster trigger, tell me so and why.  If you have gone with some sort of aftermarket trigger that you have been pleased with, which one is it and why do you like it?  Thanks!

Rock River Arms builds a sweet two stage for just over $100. Some say the springs go away and you end up with a very nice single stage. Kind of up to you.

Thanks OldTiger...anybody else?

I have three RRA NM triggers and one Armalite NM trigger. I'd rate them about equally good. I'm very satisfied with them.

I've heard that accuracy speaks makes an excellent single stage [url]http://accuracyspeaks.com/[/url] and there is also a lower spring power kit [url]http://www.brownells.com/aspx/NS/store/ProductDetail.aspx?p=16652[/url]from Brownells.
