I'm selling this for a friend. She bought a new match grade upper and doesn't need this anymore. She tells me it's a Bushmaster upper, barrel, and bolt/carrier assembly, but there are no marks on it. It was built early on during the ban, but has only 3-4K rounds thorugh it.
* A2 upper receiver
* includes bolt, carrier, and charging handle
* BM Dissipator barrel (heavy contour the whole length
* Freefloat hand guard (I think it's a DPMS)
It also has a Krebs comp (pinned on), and it works great and doesn't cause a lot of extra noise. Shooting it offhand, it pushes the muzzle down -- kind of weird, but works. This is a great shooter and a good base for an inexpensive AR. Asking
$365 (OBO) shipped to the lower 48 states.
If you need detailed pics of any portion of this upper, please let me know and I will get them for you.
