I never touched an AR before I built my first one (last week) and everything went fine. $475 Black Friday PSA rifle kit. Can't wait to try it out! Plus $150 for a Vortex Spitfire 1x prism scope which is supposed to be good, but I did exactly zero research on it before I bought it. I just went with PSA's recommendation. The FFL who did my transfer (Steve Reihl of Adaptive Firing Solutions in Oregon City 971-217-6811) very kindly let me come back and use his AR wrench, block and vise, and helped me put the spring and detente in the front pin. It went very well with four hands and a punch instead of two hands and the correct tool. It took me about two hours to put the lower together, the upper came assembled. I'm not mechanical at all. Just learned how to change my spark plugs this year (I'm 44) so don't think you need to be a machinist to get it done.
