Have a used G&P WOC, has a 9.5” Daniel Defense free float(not airsoft) and a Magpul UBR stock. Comes with 3 PTS mags and 1 STANAG. All mags have been glued with a gasket sealer but the STANAG still has a slight leak. I’ve only used this a handful of times, GBBR’s just isn’t my thing. Can be a little finicky at times but when it shoots, it’s sends them. Honestly I’m interested in some sort of fusion engine platform. Need the engine, battery, hose, and regulator.
