Alright you guys talked me into it. i ordered a 0% forging from DSA, it should be here in a week and i can begin milling it out. it seems like it should go pretty easy for the most part as long as i take my time with it. The one part that concerns me the most is going to be locating, drilling and tapping the rear hole for the buffer tube. is there any easy way to do this task? I don't have a OJI jig so i will be marking it all out with a caliper and taking reference off a bushmaster lower. Also once i finish the lower obviously i will need an upper to go onto it. i would like to go with something along the lines of a 20" A3 flat top with a 1-9 twist. how difficult is it to assemble one from parts and get the head spacing and all right? and where should i be looking for these parts? all hints, tips, and tricks, will be greatly appriciated. i will keep you all posted on the progress once i begin.
