I'm thinking of purchasing a matched mega lower & upper receiver and building the lower myself. I talked to one of your guys in Richmond a couple weekends ago and am pretty set on building a AR. If i catch up with you at a gun show, could i get you to assemble my upper with your parts. Barrel, block, tube, etc... or will you only do your own parts? Do you plan on coming to Richmond again or is it not in your normal round of shows?. Let me know.
