I have a preban style Bushmaster 16" Super Light, 1/9", A2 upper with a Mark Brown Custom CQB A2 rail mounted on the receiver.
The A2 receiver has had the carry handle removed in front of the rear sight. In its place is a MBC CQB A2 rail. This rail allows you to retain the standard A2 sights AND have a rail for mounting optics. This will allow the iron sights to cowitness with Aimpoint and similar optic sights.
The barrel is a Bushmaster 16" lightweight with a 1/9" twist. The hand guards are Rock River green M-4 style with a Streamlight light mount rail. The standard sling swivel has been removed and replaced with an ASA side sling mount similar to GGG's.
This upper will hold 1.0 MOA out to 450 yards with Isrieli M-855 62 gr ammo. The condition is 90%+.
The price is:
Upper with bolt carrier ass'y; $425 shipped
Upper W/O bolt carrier ass'y; $350 shipped
Everything in front of the receiver; $200 shipped
