R-Core - "The Master"


An accented ridge for your palm’s life line, which makes sure that your hand sits correctly and the applied force goes straight into the center of the bow and does not create any torsional forces.

    This is a quality product. With outstanding customer support.
    I just don’t have to worry about my bow hand any more as it just sits right with the new grip. What more could you want from a bow grip?

  3. Luca Rabitti (verified owner)

    Pleasant package, absolutely precise fitting in the riser, kind answer for expedition needing; beatiful colour and very comfortable finish of the material. A great discover the compounder tilt; for me it was a test, really succeeded. Maybe want to try another profile, seen the fantastic quality. I adviced many archers around me to try it and someone did; everybody happy. Thanks to Aris

    Perfectly positioned for you to shoot the same shot time after time. Comfortable, intuitive and looks good too!

  5. Matt W. (verified owner)

    Best grip Ive ever used, really promotes good hand position and makes it actively difficult to get it wrong. It fit the riser (gillo G1) perfectly.
    Only thing I wasn’t a fan of was the texture- it’s very smooth. This didn’t affect my shot in any way just meant that my hand got sweaty when shooting indoors. After adding overgrip tape ive had no issues.
    If I was to order again I would get the thumb groove – but it’s my fault for not realising they offered it.

    Been searching for a very long time to get a high wrist grip for my bow. This works perfectly for me. Looks great and fits first time. Service is top notch. Very happy indeed. Thanks Aris.

  7. David Archer (verified owner)

    Very impressed overall – very impressed with the grips thank you – would highly recommend.

    Hi, I am a barebow archer. Before r-core, with standard grip, I often took a longer time to ensure I am gripping the right way. I have to check visually the position of the grip near the palm’s lifeline, and the diagonal position of my index finger and my thumb around the grip’s neck.
    With R-Core’s “The Master”, visual check is no longer needed as I just have to slide my palm on the grip, and voilla, i got my lifeline right on the edge of the grip and the base of my thumb is exactly at the grip’s pressure point-consistently. The thumb positioner at the top of the grip really help me to feel the right knuckle angle in every shot. Now it took me much shorter time to set my shot and let me focus more on the rest of my form.
    The grip quality is very good. The material feels very solid and was precisely made. I love it!

  9. jeffrey b. (verified owner)

    Good fit. Quick delivery of my order. would recommend if you are looking for custom replacement of your bow grip.

    Having already bought a grip for my rhino and seen improvement had to get one for my spig, highly recommend

  11. Wolfgang Pirmann (verified owner)

    this grips fits my preferences perfect, narrow enough to reduce torque and perfekt lining on the lifeline, cant be happier

    Excellent Service, Communication and Product. I’m very happy with the grips for my Black Wolf risers, they have made the bow so much nicer to shoot.

    Everything to do with buying this grip and clicker plate was a pleasure. Maria even sent me pictures of all the different Yellow colours so I could make sure it all matched the rest of my setup. Main thing though was the fact that the grip actually fitted my new Gillo GT ( unlike the one from a well known US company) and it was cheaper!! All in all a very good experience.

  18. Franz Saugspier (verified owner)

    Quick conversation about technically details, fast production and finally perfect fit of the grip! I recommend this company for individual grip !

  19. Stan B. (verified owner)

    Great design. Rough and harsh feel. Will need use in summer conditions.

  20. Peter Lewis (verified owner)

    The replacement for the spigarelli revolution grip from rcore is a fantastic, so much more comfortable and repeatable a hand position. And the team at rcore were fantastic, so helpful with superb customer service.

  21. Tamás Baranyai (verified owner)

    The grip is extremely comfortable and fits perfectly to my Gillo GQ riser.

  22. James C. (verified owner)

    Best grip for consistent hand placement. It has turned my shooting around for the better.

    Perfect for me ! Great grip. Thx

  27. John Giokas (verified owner)

    Would prefer it wider at the top. Fits superb in my hand,the looks are better than pictures, fast service too. If you would like to change the angle of your grip or just the looks then is highly recomended.

  28. Colin D. (verified owner)

    Ordered a 38 and a 45 degree so I could try both, in toxic yellow!! The grips fit my bow perfectly, colour matches the logos on my bow perfectly, and the grip is a really good positive feel in the hand- shooting good scores straight away. A great alternative to the stock grip provided on my W&W TFT-G bow.

  29. Mark H. (verified owner)

    Really nicely designed bow grip, considerable improvement over the standard item for my decut. 3d printing finish is quite obvious if you would be bothered by this but doesn’t affect function at all.

  30. Joanne Spencer (verified owner)

    Love the colour, unicorn poo pink. Comfortable in my hand and down the lifeline, it does seem to make my hand sweat tho and that’s unusual for me as I’m always cold. Other than that, love it.

  31. Dave Oates (verified owner)

    Perfect fit on bow and hand.
    Raised edge helps me a lot.
    Cool colour.

    Na lang wachten (4 weken) aangekomen.
    Grip gemonteerd op boog en gaan schieten.
    Grip ligt meteen goed in de hand.
    Aris bedankt.

    Buying the grip was a trouble-free experience. R-Core (Aris) are very easy to deal with and supplied me with a custom grip for my left-hand Spigarelli Club 650 riser very quickly. I’ve ordered a similar grip for my Stolid Bull Black Thunder riser and I’m looking forward to buying more grips fromR-Core (Aris) in the months to come for my other risers. Very best wishes for the future, James Moloney, Ireland.

    I was looking for a grip with a harder edge down the left side (RH shooter), to give a more positive and grippy hand placement, particularly with damp hands. The Master looked about right. Bought it in a medium height and it’s a PERFECT shape for my hand. The hard plastic texture is a bit off-putting at first but it works well under pressure and I can’t fault it functionally. Fit on the riser is also extremely good. Not sure luminous green was the best colour choice but that’s my fault! They aren’t cheap but they work very well. I have recommended them to a few others at our club but I’m kind of hoping they don’t get them so I can stay one step ahead ; )

    Immediately fitted comfortably in my hand. My alignment was instantly improved. The left edge hits my lifeline perfectly and my thumb position is massively improved. A joy to shoot and the bow remain stable and balanced even when string walking. Absolutely top class product..

  38. Alexander Lebedinskiy (verified owner)

    The grip itself is amazing: the color, the material, the fit, the craftsmanship are top-notch.
    The shape is very well thought through and the amount of available customization is mind-blowing. There actually would be almost too many options to choose from if not for the caring, highly professional customer support that sorts out all questions together with you.
    My grip works wonderful with my Gillo GQ – the size is the exact match. Through customization, it also matches perfectly with my hand and my shooting style. Going for a lower angle, as advised by the manufacturer, resulted in a much more stable shot with considerable string crawls. And I absolutely love the thumb groove!
    Thank you once again not only for a great product but also for a great experience I had while ordering and are having while shooting. I’m getting another grip for my better half from you, this time in Unicorn Poop color 🙂
