Kopfjager Reaper Tripod Accessory Rail System Picatinny Black. The Reaper Rail mounts your rifle with Arca Swiss rails to medium and heavy-duty tripods with 3/8-16 threaded studs. The Reaper Rail allows for both vertical and horizontal travel allowing you to swivel with ease making follow-up shots easier. This patent-pending innovation eliminates the need for slight adjustments to the tripod if it is not level. The 11 degrees of rifle cant (both directions) gives the shooter the opportunity to quickly level the rifle while setting up for those hasty shots in the field and gives a more compact lighter-weight alternative to our original grip without sacrificing stability. If you currently own our reaper grip you can convert it to a Reaper Rail with just the purchase of the Rail Plate and Cant Level (mounting screws included). Tripods with the smaller 1/4-20 threaded stud require an included adapter to allow it to work on those models as well.
