I see an ad in Gun Digest magazine M&A Parts out of Illinois with reasonably priced AR uppers does anyone Know about this company? Has anyone here purchased an AR upper from this company? Imthinking about buying a Car upper flattop for my Colt AR 6700. Their price is $295 for the crome molly heavy barrel. I talked to a guy there about 2 months ago and he said my bolt will work in this upper no problem. Any help from you Ar guys would be appreciated thanks PB

Try asking on AR15.com

M&A are pretty good to deal with, i have bought more kits from Model 1" Sales online as well with no problems
