Buy a stripped lower, and a lower parts kit, watch a couple of assembly videos and TA TA! Now all you need is a complete upper and a brace or stock depending on the end product desired. I used tools on hand to build the lower, bought the upper assembled, I did however by an AR armorers wrench for tightening the buffer tube nut. (sorry forgot the torque spec.)
I will ask this question, whats the deal with .154 pins for the Fire Control Group? Apparently there are different sizes, why?
Thanks in advance
