The R500 features the all-new proprietary HexCoil Cam System that rotates cams 360 degrees and has reformed traditional crossbows into the fastest, most accurate and compact design ever seen. Completely silent, this crossbow uses the new R500 Draw Handle and cocks back to a slim 3.6 inches when fully cocked, firing arrows downrange at 500 feet per second. The R500 utilizes the new VersaDrive Cocking System that has an internal screw drive that moves the Trac Trigger Firing System (TTFS) back and forth. The internal clutch within the VersaDrive System eliminates over-cocking and allows cocking and uncocking to be stopped or resumed at any time. The R500 can be upgraded to the R500E by purchasing the new Electric Drive Kit, sold separately.
