Well, I hope I never need it for combat, but if so this is the one I'm grabbing.
My first Ar started out as a bare bones olympic arms pre ban shorty that I picked up right after the AWB. I "pimped" it out as much as I had a desire, and built myself another AR; in a full sized m-16a-2 format (minus the 3 shot burst). I really am/was pleased with my 2 AR's but I had heard a lot about rock river arms and how many said they were the best out of the box AR's on the market, so I thought I'd give them a shot.
Starting out I was planing to buy a new trigger group and a new rra upper for my shorty, but I noticed the pro ELITE series on RRA website and thought; " if I sell my full sized AR and do some saving I can swing this". After selling my built AR and saving for a butt load of time I finally ordered my baby. Weather or not it was worth the money or not remains to be seen; with all the crappyweather we have had lately I haven't had a chance to take her out, but when I do, I'll let yoyu know if it was worthm what I paid or not.
So far, as the magic 8 ball says, "all signs point to yes". The upper and lower fit together with little to no slop, and the bolt sounds like it's moving on ball bearings when I hand cycle it.
Ah well, I hope she shoots as well as I expect, but time will tell.
