This was my extra chassis, so its been a tad modified to try new things. I had a thumb shelf on it, when I went to remove it, the screws snapped. So sanded smooth and drove on. It has a modified MPA grip, with a built in epoxy thumb shelf now. That's the bubble gum looking thing. Its been trimmed to accept and action with a trigger hanger (pics). Its also has Brownells aluma-hyde sprayed on half, never got around to the other half. Yes, its rough but 100% functional and cheap. $350 shipped.
