I have a Bushmaster A3 flatop upper, 16" M4 type barrel, A2 hider. Excellant condition with a few scratches on the rail, will included bolt, carrier and handle. I DO NOT have a rear sight for it.
Looking for a A2, A3, or A4, would be interested in any upper(maybe even different length barrels) except I dont want an HBAR. Must have bolt, carrier and handle. Not looking for anything fancy, Oly is fine by me.
