FX wildcat mk2 compact

N2stuff, what tool did you use to cutout for the gauge and hammer?

A Dremel with a sanding drum. I still need to round off the edges before I dip the stock. I want a jam nut to keep mine from backing off too. I've been playing with slugs and ran out of hammer throw. I don't know if someone makes either a heavier hammer or spring as they do for the Crown? I also installed an Huma and started at 150bar. I'm now up to 170bar trying to get the slugs up over 900FPS. Right now they are at 895FPS.
