Good for you man!I followed your thread from the start since first posted to see how it turned out and I'm glad to see they (aero-precision) took cake of the problem for you!Thats good to know when a company steps up to the plate!Some of the 'best' AR companys out there would tell you that you have to 'pay' for their 'mistakes'.Anyway, also good to see that your lower went together smoothly.The 'propper' roll pin punches do make a world of differance when it come to quality craftsmanship and gettin' it put together right the first time!Have a good one!
