The clamps work great and they mounted easily to the RIP-M. I had to trim the inside "teeth" of the large clamp a little so that it would fit around my handguards. Took about ten minutes with a razor knife. If you have larger handuards, you may have to do the same. I was also a little worried that the mounting screws would rub on my seat back. I made sure not to tighten them too much and used a little drop of Locktite so they wouldn't back out. My MPX fits perfectly and it is solidly mounted. I love this setup!
