finally got this built, I had the kit and receiver for a few years now. I got in a small run of these to do for a commercial customer and did mine to work out the build process. I had it out to the range last weekend and ran 250 rounds through it, only had 2 stopages that were failures to feed possibly because of short recoil. it ejects out the left and the guy shooting on that side was ankle deep in 54R brass!!
I riveted the trigger housing on today now that it is working right. I hot salt blacked the receiver instead of painting it, I will most likely do that to the rest of the parts in the future as I am not a fan of painted guns.
