Shibuya's innovative Tria-Lock system keeps the scope rod approx. 1/2" closer to the elevation bar than conventional target sights. This significantly reduces moment effected on the windage unit – a significant factor in development of play and faults! The innovative new Tria-Lock system encloses the scope rod holder from three sides, keeping it perfectly aligned and without play to produce a rattle-free, zero-tolerance environment.
The ULTIMA CPX's X-Lock offers a re-adjustable, zero-tolerance fit between the windage unit and sight frame. Now with CPX-exclusive polyacetal resin sliders, offering even more contact area for an even more secure fit.
ULTIMA CPX's X-Lock sliders have additional leaf spring functionality, offering the ultimate in elevation snugness and precision.
ULTIMA CPX features Grade 5 Titanium alloy lockdown bolts for 2nd and 3rd axis adjustments, as well as Nord-Lock® washers to lock them firmly in place. All aluminum sight parts are machined in Japan under strictest quality control.
