$25 shipped in the US. As I've told many people over the last few weeks. I have about 30 of them, but in BETA testing some people experienced leaks, in particularly when they screwed the can in too tightly. I use one size up on the o-rings that seal either end of the firing chamber to reduce this possibility, but because we never went into production with these on a major scale I do not warranty them in any way. Its a buy at your own risk kinda thing. I'm pretty confident most uses wont have any issues with them but I can't promise it so I want to put that right out on the table.
Yeah, mine started leaking.. i even put thicker orings on to try and stop the leak, to no avail. If i chrono at 260 it has no problem sealing but 285-300 just wont seal
