Hmmm. I have one I built. I'd need top dollar for it. 2x30 round mags, 3x20 round mags. Built on a Global receiver by me several years ago. Duracoated by me.
US parts are piston, 3 piece FCG, brake, receiver for a total of 6 parts.
Nice dark bakelite grip to match the beautiful wood.
Underfolder is tight. I used those weird U Drive rivets and some allen head screws that had the heads filled and sanded over before painting.
