The MR Hop bucking is essentially a drop in R-Hop bucking. Easily extend your range and increase your accuracy with this bucking. This is as close to R-Hop performance you can get from a hop up bucking. These do require larger windows and pair well with any of our EDGI barrels that we have available. We found that the 60 degree and 70 degree to work the best in majority of builds. Maple Leaf recommends to pair this bucking with their Omega Nub for optimal results.
