I need.......Well, OK want an inexpensive complete upper. A3/flat top, and as short a bbl as I can legaly get. I want it to slap on my Bushmaster lower for fun, just spraying many rounds down range.
It does  not need to be pretty, and I don't care about how many rounds down the tube, this is just for fun.

I don't have a lot of money to drop on this, maker is not a big issue to me. For the SHTF situation the Bushmaster upper and Holo sight will be on anyway.

IM or email if you have any suggestions

thanks!
Joe

the shortest is 16" oal either bbl. alone or with a permanently attatched muzzle device.


look around and figure out what you are trying to do first. cheap? keep an eye out in the equipment exchange.
