I've got a 19" Large shank stainless Mcgowan barrel chambered in 6mm-284 it has exactly 136 rounds down the barrel proper break in procedure was done. It cleans and shoots very good. The barrel shot very good with h-1000, fed 215m primer but shot best with cci br2 and 115 d-tacs.
I'd like to get at least $220 shipped for it new they are $250. Reason for selling is I'm having same caliber built but longer barrel 28" this time.
