A new chapter in the history of the world’s most popular Target Recurve Sight.
Continuing the 20-year Tradition of ULTIMA Recurve Sights. Since its debut in 2005, the ULTIMA RC has been the sight of choice for medalists around the world. The latest RC IV model carries on this proud tradition, delivering even greater precision and operability for today’s competitive archers.
Since its introduction, the ULTIMA RC series has earned the trust of archers worldwide for its precision, stability, and reliability.
The ULTIMA RCⅣ continues that proud legacy, embodying the steady evolution of SHIBUYA’s craftsmanship and attention to detail.
Every aspect of the sight has been refined to provide an even smoother and more precise shooting experience.
The adjustment mechanism now offers finer micro-tuning for more accurate sight alignment, backlash has been completely eliminated for consistent feel, and maintenance has been simplified to ensure lasting performance with ease of care.
By preserving the proven structure that defines the ULTIMA series while enhancing every operational detail, the RCⅣ represents the next chapter of a trusted design—one that feels instantly familiar, yet distinctly improved.
The Standard for Competitive Recurve Sights — Perfect Balance of Weight and Functionality
The ULTIMA RC Sight, trusted and proven through countless international competitions, has been renewed and refined.
With SHIBUYA’s finest micro-adjustment click interval ever and improved maintainability, it delivers the precision and reliability demanded by top-level recurve archers.
Finer Adjustment — SHIBUYA’s Smallest Click Increment
Vertical and horizontal adjustments now move approximately 0.04 mm per click, an improvement from the previous model’s 0.05 mm.
This enables ultra-fine tuning to meet the micron-level precision demanded by competitive archers.
Zero Backlash — ZPE System Integration
The ZPE System, highly acclaimed in the CP PRO and CPX III series, is now adopted in the RC lineup as well.
By optimizing the internal structure, true zero backlash has been achieved.
Even during reverse adjustments, each click responds firmly, allowing for more accurate sight calibration.
Quick-Release Sight Pin Stopper
This allows smooth, one-touch adjustment and significantly reduces setup time—helping archers stay composed even under time pressure.
Sight Scale Plates
Both sides of ULTIMA RIII’s elevation bar feature metal sight scale plates. Each ULTIMA RCIII includes a standard scale plate, as well as a blank plate for a printed tape. Left and right are interchangeable, to fit any archer’s preferred shooting style.
X-Lock System US Pat No. 7,287,335
Re-adjustable, zero-tolerance fit between the windage unit and sight frame. Super-slick and durable polyacetal resin guide spacers enclose the elevation rail, re-adjustable at the turn of a set screw. All parts field-adjustable and -replaceable!
New, maximum grip dial finish
ULTIMA RCIII sights feature completely reworked dials and mounting knobs, making every adjustment delightful and enabling the user to securely tighten the mounting knob more easily and securely than ever!
Enhanced Maintainability — Built for Long-Term Use
Parts susceptible to wear over time have been redesigned for easier maintenance.
Replacement and cleaning of consumable components can now be performed more efficiently, ensuring long-term stability and consistent performance with proper care.
