[The upper has been sold. Thanks!]
I'm going with a mid-length A4, and am putting my Bushmaster upper on the market.
It is a Bushmaster A2 post-ban 16" upper (chrome lined, of course), w/bolt & carrier assmebly and charging handle. It has about 700 rounds through it, (no more than 700). I'm selling it with everything in the photo: a California Competition Works bi-level mount, black & green handguards, a GG&G UFIR, and a GG&G Sling Thing (I'm throwing all that in for free, it's not adding to the price).
Price: $400 shipped. Payment in money order, please. Thanks!http://i49.photobucket.com/albums/f296/btall/upper.jpg
