Fully integrated into the stock, the ACUdraw 50 SLED has taken the leveraged, 50 percent reduction rope-cocking concept to an easy to use level. Its cord retract neatly inside the units housing after cocking. Lightweight, contoured covers provide improved security of the unit and its cord when not in use. No storing a cocking rope, untangling it, or putting it away after each use. Compatible with all TenPoint and Horton crossbows with Functionally Superior Bullpup (FSB) stocks, including ultra-narrow and reverse-draw crossbows (except the Nitro X) and most Wicked Ridge crossbows
