Built my lower today, minus the stock and take down pin since it requires the stock /buffer assembly. I enjoyed it and look forward to more parts arriving in the Mail. Part on back order etc. Anyone building a ar15 today knows what I am talking about. The only problem I had was with the bolt catch pin. I was difficult to get it in. Had punches but not a roll pin punch. pin about 80% threw. holds just fine and wont be a problem except I know it is not perfect. Might get another pin and proper punch and try again. I made my own tool to install the pivot pin/detent/spring. Used a 1/4 in allumnium rod. about 5 inches long. Filed one end to a near perfect 90 degrees. Drilled a hole just big enough to allow the spring and detent to pass thru. Pushed them thru, rotated the pin 90 degrees and carefully followed the pin, did it on second try. Worked great. And I didn't have to buy the little tool. Every thing else,, smooth as silk...
