Owners report these go straight into the SE McCarty 594's existing bushings with just a screwdriver, no drilling. It must be the non-collared KRGLNC version: one owner bought the collared KRGL first and it would not fit. Nickel matches the stock hardware.
Why we say this
Evidence: two independent owner reports of a no-drill fit on SE McCarty 594 (PRS forum thread on installing Kluson Revolution on SE 594, where KRGL-3-NP failed and KRGLNC-3-NP was the fix; JustinGuitar community post on SE 594 Singlecut with Kluson Revolution non-collared, original rings kept). Hardware is identical on the double-cut and Singlecut per PRS spec pages. Screw hole alignment not independently measured, so Likely rather than Verified.
