The newly designed 2nd generation BRP M10 Flexx Mounts use a 10mm bolt that threads directly into the steel pivot pin on the Fasst Company Flexx Bars. This new and improved design is stronger and more durable than the previous design which utilized an 8mm bolt. The BRP M10 Flexx Mounts will allow you to mount most popular style aluminum hand guards to your Fasst Company Flexx Bars. The BRP Flexx Mounts were designed in such a way that they do not prevent the flexx system from working. The BRP Flexx Mounts were designed exclusively for Cycra Probend hand guards and in most cases can be used with other aftermarket hand guards with little modifications. The Flexx Mounts are manufactured from billet 6061 T-6 aluminum to our high quality standards of fit and finish and feature our signature black anodize with laser etched BRP logo.
