Here's a pic of the upper complete except for parkerizing and a muzzle brake. I'm going to try to make a levang type muzzle brake for it, but not to tame the awesome fury of the mighty 9mm luger round as it seems to kick about as much a a 22lr bolt action with CCI stingers. I want to make a levang type brake for it as they seem effective at directing the noise away from the shooter. Which is always nice for young shooters. It feeds fairly reliably with one bullet flipping up and jamming out of 2-3 magazines. I might be able to eliminate that by trying different spacing of the feed lips or smoothing out the feed ramp a little more. With the caterpilliar barrel lock nut on there Muttman joked that I should stamp it "Powered By CAT" But in the mean while since we're still in a severe storm warning, I put the snow camo stocks on and took a picture between snow bands.
