I have two AR-15 pistol uppers for sale. I got them in a recent deal, and as a result, I do not know how many rounds have been through them, but the their bore looks great, and both uppers are > 97% cosmetically. I have not used them, so I cannot tell you much more.
One is in A2 configuration, and the other is a flat top (carry handle not included). Both have 7" barrel, free-floating handguard, flash-hider, and bayo lug. Neither comes with charging handle, bolt, or carrier.
I do not know who made them, but the A2 upper looks identical to that shown at jtdistributing.com, (except it has a different flash-hider). The flat top looks similar, except it's a flat-top [:)].
Price is $250 each, shipped, OBO (USPS MO or Paypal only). Please e-mail for pictures (firstname.lastname@example.org).
