Pillar CZ 455/457 Slim Knurled Grooved Bolt Knob – Black
The Pete's Pillars PP4KG Slim Knurled Grooved Bolt Knob combines a streamlined profile with a textured gripping surface for CZ 455 and CZ 457 rimfire rifles.
Precision CNC-machined from billet aluminum, the PP4KG features a combination of machined grooves and knurling, offering a comfortable, tactile alternative to the standard factory bolt knob.
Its slim proportions make it a natural choice for precision rimfire competition, benchrest shooting, hunting, and recreational range use without the bulk of an oversized tactical-style knob.
Slim Profile with Knurled Grip
The PP4KG combines two distinct machining features: knurling for positive grip and circumferential grooves for a distinctive contoured profile.
The additional texture provides a secure contact surface, while the machined grooves break up the exterior and give the knob a refined appearance.
Unlike larger competition-style knobs, the slim design remains proportional to the CZ rimfire action, making it an attractive option for shooters who prefer more restrained ergonomics.
For a similar profile with a smoother surface, consider our PP4SG Slim Smooth Grooved Bolt Knob.
CNC-Machined Billet Aluminum
Manufactured by Pete's Pillars from solid billet aluminum, the PP4KG offers lightweight construction with precise machining and consistent exterior details.
The black finish complements factory CZ hardware, traditional sporting stocks, and modern aluminum chassis systems.
Its combination of aluminum construction, slim geometry, and machined texture makes the PP4KG a practical upgrade for shooters who appreciate both functionality and craftsmanship.
Designed for CZ 455 & CZ 457 Rifles
The PP4KG is designed as a replacement bolt knob for compatible CZ 455 and CZ 457 threaded bolt handles.
Its enlarged gripping surface provides a more substantial contact point than compact factory-style knobs while retaining a streamlined profile.
The knurled exterior is especially well suited to shooters who prefer additional tactile feedback when handling their rifle.
Verify that your existing bolt knob is removable and that its threads are compatible before ordering. This product includes the replacement knob, not a complete bolt handle assembly.
