Posted this over on the other forum, but figured I would reach out here as well for some insight. Recently purchased another GenIII Archer off GB and picked it up today. Was sold as a "gunsmith special" due to the fact that it did not run consistently. The previous owner had the mag well and trunnion hogged out and installed a CANIS M4 adapter. Radom mags lock in, but wobble like crazy. Looking for options. Can the well and trunnion be built up with weld and remachined, or am I asking for trouble. Will post up some pics when I have a chance, but any help/suggestions are appreciated.
