The Ultima RC PRO G2 520 is Shibuya's 2025 generation of competition recurve sight, made for archers who need their settings to come back exactly the same, shot after shot.

The clearest change from the previous generation is the polygonal carbon extension. The profile replaces the round bar, cuts down on torsional flex and vibration, and adds less weight out front. It attaches through the click-ball mount, which lets you return to a position you have already dialled in whenever the bow goes back together. The elevation bar and sight block are machined from 6000-series aluminium alloy, the extension is carbon.

Inside, the ZPE system works against play in the adjustment. Clicks stay firm when you turn back, so a correction puts the scale exactly where you expect it. One click equals 1/640 inch, roughly 0.04 mm in both elevation and windage. That is the finest increment Shibuya has built to date and a touch tighter than the 0.05 mm of the Ultima RC III. Elevation runs on a lead screw with no lockdown screw and adds a jump mechanism, so a large distance change can be slid rather than clicked through.

This version is the 520 with a 5.2 inch elevation bar and single mount. Its 107 mm of travel leaves headroom for long distances and moderate draw weights. Tilt adjustment covers second and third axis alignment, and the aperture sits anywhere between 83 and 249 mm from the bow.
