I'm curious how the cadex MX1 muzzle brake compares to other options. It seems like a good design! I've got one on order, and I'd love to hear if it's comparable to the APA little bastard (or similar) for effectiveness. I'm planning to put it on a AI axmc in 6.5cm. The whole rifle weighs 17.5 lbs, so it's not like this is a big recoil rifle anyways. I'm expecting good things from the cadex brake, and I'd love to hear your experience.
