Working in conjunction with the Trac-Trigger Firing System the Versa-Draw Cocking System is an ultra-compact fully integrated cocking mechanism is built into the sleek stock design. Featuring a minimal 12 pounds of cocking force. It is ambidextrous and has the ability to cock and un-cock your Ravin crossbow. The cams rotate 360 degrees, reforming traditional crossbows into the most compact designs ever seen. A built-in trigger mechanism that slides forward on the rail and clasps directly to the precise center of the string every time the bow is drawn, allowing for straight-line nock travel. This technology allows the arrow and string to free float above the rail, eliminating friction for consistent accuracy and increased string and cable life. The cocking mechanism allows you to stop the draw cycle at any time during the cocking process. You can dial in your yardage with a twist of the turret on this red & green illuminated scope.
