Seriously downsizing my collection, most of these guns have never been used. Matrix M4 with microswitch trigger, quick change spring guide and upgraded V2 Lipo ready gearbox. Comes with 13.5 trademarked Geissele replica 13.5 URGI rail. Rail is a little beat up but. Dytac motor grip, rail sections and foregrip. NO other attachments included. NO TRADES, NO PARTING, requests will be ignored.
