I bought a poly 80 kit and the parts from various places. The slide and lower parts are Lone Wolf, barrel is from optics planet house brand and slide from ebay. Everything looks well made with no tool marks, even bluing etc.
Frame was easy. Drilled the holes, cut off the tabs with a sheetrock knife then sanded smooth. Everything went together fine until installation of the slide and barrel. It will not slide completely one the frame. The bottom of the feed ramp is hitting the block and won't clear.
Should I file the flat bottom under the chamber of the top of the block until it clears. I am leery of filing on the barrel as it might mess up the ramp but will try it if I have to.
