Top notch receiver's


I was skeptical about this receiver but I noticed that it was made by mega arms who make some very high quality parts. I have receiver's from sons of liberty gun works and this has the same deep black finish and extremely tight fit as those. I am 99.9% sure solgw gets their receiver's from mega, especially when you see their m76 handguard it's just a mega wedgelock. This expo receiver has a real nice magwell flair as well. Buy with confidence, these receiver's are among the best. Just realize the anodizing is darker than most milspec and has a slight sheen to it, so match it up with expo, solgw, mega or Rainier arms upper if you want a perfect match and tight fit. If you want to see how the fit is check YouTube "solgw receiver sets "
