This is an HPA-Rady GBB pistol set up with a ReMag magwell. No fussing with buying 12 mags nor pressure drops with green gas. Just feed it air and it's ready to go! This magwell is also using my new connector style, which trades the older threads for a more robust snap-clip and lug. Comes with: -WE 1911 -ReMag remote magwell and feed lines -Basic highcap magazine Ships via USPS Flatrate *If you're simply interested in a magwell, let me know and we can get you a setup for your gas colllection!
