I bought 1 of their M4 kits about 3months ago. I had some problems with putting together the fire control parts, mainly because the selector wouldnt go in because the back side of the trigger was too high. I replaced the trigger and selector that came with it with extras I had from Rock River and it works fine now. I would have to say that it is accurate for the cost and with the exception of the trigger and selector, have to say it was a good buy. I currently have mine set up with an Olympic Arms FIRSH handgaurd and an EO Tech sight. It currently rides with me in my Patrol Car and I love it. There are those that will lead you to believe that non-chrome lined barrels are crap and that your better off with chrome lined which may be true but, my views are that I shoot quality ammo with it and I clean it after every use. I'm not humping it on long patrols in the boonies and am not swimming with it so it suits me well and its still easy to clean.
Just my 2 cents....
