At this years SHOT Show I ordered a Geissele Mk18 rail. I had it coated Magpul FDE and then stuffed in my Compass Lake Engineering rimfire guts. The barrel is a Douglass or a Lilja with an old JET titanium integral suppressor. I have mainly been shooting my Vudoos lately, but sometimes a semi-auto is so much fun. And being able to toss it on my tri-pod anywhere is pretty cool as well.

S&B 3-20x50 in a Spuhr mount on top.

I also had the barrel modified to a "cone" breech face to give more room for gunk to go when shooting suppressed.
