Masse KP offset feed. Good shape, soldier is a little runny where top tube meets body. Has milled 12 gram plug (not fast changer) and aftermarket masse ventri bolt.
I pulled this gun out to test and chrono at the beginning of August and it was leaking from the valve (or maybe the 12 gram face seal) so I have lowered the price to 550.
Bore is large on this so I have lowered the prices to 450. Still leaking.
