The ULTIMA CP PRO 3D & target compound sight combines the proven features of the ULTIMA CPX series sights, with the brand-new polygonal extension and Advanced Lock Mechanism found on the RC PRO sight. The polygonal extension shape, combined with high modulus carbon material, eliminates 80% of initial shot vibration*. The circular chamfer on the mount lock provides a more secure lock and repeatable aperture distance setting than ever before!New to the ULTIMA CP PRO are laser-engraved sight mark plates, which can be mounted in recessed slots on both sides of the 4” elevation bar. 15 scales and one blank plate are included with each ULTIMA CP PRO.In addition, the ULTIMA CP PRO includes, for the first time in ULTIMA history, a front detach block. The detach mechanism is comprised of two “teeth” featuring a polygonal dovetail, holding the windage unit perfectly tight from both sides.
