Bushmaster post-ban 20" A3 upper receiver assembly. Chrome lined barrel and chamber, 1/9 twist, excellent condition, less than 300 rounds fired. A few very small marks on the top of the receiver from mounting the carry handle; I'd rate this upper a conservative 95%.
Bushamster gets $395 plus shipping for this upper w/o bolt/carrier/charging handle and $535 plus shipping with b/c/h.
$320 shipped w/o b/c/h ($300 FTF in the D/FW area)
$450 shipped with b/c/h ($430 FTF in the D/FW area)
(Carrying handle is not included in these prices)
