# RCore Custom Bow Grips
> RCore (rcore.co) is a Greece-based manufacturer of custom, made-to-order bow grips for recurve, barebow, Olympic, field, and traditional archery, plus archery accessories. Every grip is precision-engineered and test-fitted on real risers, supports 70+ riser interfaces (100+ riser models), and can be configured by model, material (plastic, glass-like, automotive-painted, wood), color, grip angle, handedness, anti-slip texture, and custom engraving. Ships worldwide.
Key facts:
- Tagline: "Precision-engineered. Built for your hand, not the masses." Custom bow grips for archers who don't accept factory defaults.
- 12+ grip models across shooting styles and hand sizes, including signature lines co-designed with two-time Olympian Jake Kaminski (the "I AM" series) and Olympian Patrick Huston (The Curve Eternal, YeO).
- Engineering philosophy is material- and riser-agnostic: designs are digital blueprints adapted to each supported riser, so an archer keeps the exact same grip feel across different riser brands.
- Materials: Plastic (affordable, wide color range), Glass-like (hard, transparent, ultra-smooth), Automotive (primed, painted with 2K metallic paints and varnish), and natural single-piece Wood (walnut, cherry, iroko).
- Grip angles: Low (30°), Mid (37.5–38°), High (45–46°), "Compounder", and fully custom angles on request.
- Unique Scan'n'Print service replicates a customer's existing hand-shaped grip from a 3D scan onto any supported riser.
- Grips price range: €44.95–€94.95. Production takes roughly 5 (plastic) to 15 (wood) business days; worldwide shipping via UPS or Greek Post.
- Customer rating around 4.9/5 across store reviews. .
