Thanks, good to read you had a good time in North America. Stay away from New Jersey and your opinion will remain untainted heh. FighterAce gave me some ideas for a rear sight so here it is. Ghost ring, with waaay excessive windage adjustments, but who cares!

Still needs some paint touchups

Pretty good... honestly though, you can get some pretty cheap sights off eBay that will look a lot more professional, though I have to say I like the look.

Hey guys, haven't had a lot of time to work on my various projects, but I finally got around to taking a shot with the heavy duty dart, albeit without the foamboard backing. So this shot, if my video loads properly, is at 155 psi, with a heavy plastic coned dart pushing a 3.25 inch framing nail, no sharpening was done and again this is just the cone with epoxied nail, no foam seal. Target is 20 yards away, but don't take accuracy into consideration because I'm rebuilding the stock and this test was with no stock or sights. Target is 3 pieces of 5/16 inch outdoor plywood, each piece is seperated by approx. 1/2 inch of air. You can see the video, but the dart and cone go completely through the 1st peice, cone and nail head are stopped by 2nd piece, and the nail easily goes through all three, I think the pointy end would have gone through 5 pieces with the same result. Sorry bout the length my video editor isnt working:
