Pillar CZ 455/457 Slim Spiral Knurled Bolt Knob – Black
The Pete's Pillars PP4TK Slim Spiral Knurled Bolt Knob combines distinctive spiral machining with a textured gripping surface in a streamlined design for CZ 455 and CZ 457 rimfire rifles.
Precision CNC-machined from solid billet aluminum, the PP4TK features flowing spiral contours and knurled exterior detailing, providing a comfortable gripping surface without the bulk of an oversized competition bolt knob.
Whether you're updating a factory CZ 457, refining a precision rimfire competition rifle, or simply looking for a distinctive replacement bolt knob, the PP4TK offers a practical combination of ergonomics, machining quality, and appearance.
Spiral Knurled Design
The defining feature of the PP4TK is its spiral-machined profile combined with knurled surface texture.
The spiral contours give the knob a distinctive appearance, while the knurling provides additional traction and tactile feedback.
Its slim proportions remain well suited to the compact CZ rimfire action, offering a more substantial gripping surface without the oversized appearance of larger bolt knobs.
For shooters who prefer the same spiral styling with a smoother gripping surface, explore our PP4TS Slim Spiral Smooth Bolt Knob.
Precision CNC-Machined Billet Aluminum
Manufactured by Pete's Pillars from solid billet aluminum, the PP4TK delivers lightweight construction, precise machining, and a clean black finish.
The aluminum construction keeps weight low while allowing the detailed spiral and knurled surfaces to be machined directly into the knob.
The black finish complements factory CZ hardware, traditional rifle stocks, and aftermarket chassis systems such as the MDT Oryx.
Like our other American-made bolt knobs, the PP4TK reflects Pete's Pillars' emphasis on thoughtful design, clean machining, and practical improvements.
CZ 455 & CZ 457 Compatibility
The PP4TK is designed as a replacement bolt knob for compatible CZ 455 and CZ 457 threaded bolt handles.
The slim spiral design is suitable for a wide range of rimfire rifle configurations, from factory sporting rifles to dedicated precision target builds.
Verify thread compatibility before ordering. This product is a replacement bolt knob, not a complete bolt handle assembly.
