Taller risers offer a better feel and more options but mounting gauges or attachments have always seemed clunky or more of an afterthought. We wanted to make something that with attachments and adaptability in mind. From my time in the military, found the picatinny rail found on almost every rifle these days to be a ubiquitous way to confidently attach accessories to your rifle. It almost came as a no brainer to try to adapt that to other applications. With a Rail front and back on each riser, it offers numerous ways to place your attachments in the perfect spot for you as well as run multiple attachments at the same time. We are planning to offer sing and duel pod gauge mounts for Harley's, Indian ride control display, fxbb digital gauge and even a power vision display mount. These will be released in time. Please let us know what attachments you would like to see first!   1" of additional pull back.  come in type 3 hard anodized black for durability and UV protection.
