In this video from Evike.com's The Gun Corner, Matt goes to the WOC Series, which is the Gas Blowback Rifle Series from G&P. Rather than a kit, this is pre-assembled G&P Magpul WOC, which is similar to the G&P Sentry but kitted with the Magpul PTS furniture. With Magpul and PTS separating, this might become a rare item. Check the video below.
