Bear archery bearx crossbow de tac cocking crank - Bear Archery BearX Crossbow De Tac Cocking Crank

It works on my Bear Catalyst 420 as stated. It does get hung up after cocking under the scope mount. I just have to give it a little shove to release it. Not a big problem but could have been made a little narrower.Maybe because it's it's made to be used on several different models, it may fit better on the others. Still works great and much better than using the cocking rope.
