Original owner. Shoots almost 5 magazines as though it's regulated. As accurate as anything I own at 50 yds with the exception of my Mutant. Definitely outshoots my $2K LCS. Includes 2 mags, probe, single shot tray, O-rings, hammer spring, shroud and everything that came with it originally in original box. Also included is a super quiet 3D printed moderator. Only used in the basement and on the bench. $325 plus actual double boxed shipping. Pick up in Central Ohio. Scope and rings available separately if interested. Paypal FF or plus 3.5%. I have a page of references on the old Yellow BOI. May trade toward Taipan, latest gen Edgun, Uragan, Mk II Impact, or electronic Daystate.
