Hanger/stirrup for Ravin, or most other brand crossbows, with a picatinny rail. Hanger/stirrup adjusts to the length of arrows so no more arrows hanging out past your foot loop. Hanger/stirrup slides all the way down so you can fit your bow in a case.
You will have to relocate the quiver/crank handle bracket on Ravin crossbows.
Please note some picatinny rails may have some variance in size so fit maybe tight, the hanger/stirrup may have to be tapped into place.
