BOTH ITEMS TRADED!!!
I have a used Swan #38 BUIS up for trade. It's marked "5.56 M16" This is the picatinny rail that's the full length of the upper receiver and has an integrated BUIS sight at the rear. It has a small nick on the bottom right side which isn't visible when mounted on the gun. Looks great.
I also have a brand new black ERGO grip with plug.
I'm looking for misc. 1911 parts such as NEW beavertail safety, mags, etc. I'm also open to AR mags, Magpul products, etc. Make me an offer!
