I have this Bushy upper built with a CMT t-railed upper and Predater P4 rail system. It has a DPMS gas block and a flip front site of unknown mfg. I am trying to get back to a stock Bushy carbine. If you are looking for a tricked out upper this is a great deal, as I have almost $300 in accesories on this thing. WTT for a preban bushy carbine upper plus some cash to boot. I would forgoe the cash to boot in exchange for a Ace stock.
I'd really be willing to deal for a Bushy M4 upper. I'd take a BM m4 upper a3 with carryhandle as even trade.
Maybe 500 rounds down pipe, very clean, in 98% condition. No malfunctions, not even a hiccup.
The barrel is 14.5 and the brake is threaded and pinned on. It would not be hard to replace it with a F.H., heck I'll even throw in an A2 FH.
Lower, vert grip, scope, rail covers, bipod, rear buis, and backyard are not included.
Additional pics available to interested parties.
Thanks for looking!
