I*ve had this gun for more years than I can recall. It*s always performed well but I have decided to assemble a second upper for it just to mix things up a bit. Perhaps a second lower is in the future but I*m fine to just swap them out for now. Slide is from K and M tactical, barrel from Salient Arms, sights are Ameriglow, and the other things should be self explanatory. The parts are generally Glock oem that I had on hand from various projects throughout the years. Thanks for looking and any suggestions or feedback appreciated.
