PETE'S PILLARS | PRECISION RIMFIRE CONTROLS
A Better Feel Every Time You Reach for the Bolt.
The Pete's Pillars PPFGL XL Finger Groove Bolt Knob gives CZ 455 and CZ 457 shooters a larger, more natural gripping surface. CNC-machined in the USA from billet aluminum, with M6x1 threads and a distinctive contoured profile, it's a small change you'll notice every time you handle your rifle.
Factory bolt knobs get the job done, but there's something satisfying about a bolt handle that fits your hand. The Pete's Pillars PPFGL combines an oversized profile with machined finger grooves and subtle gripping texture. Whether you're on the bench, working through a stage at an NRL22 match, or simply updating a favorite CZ rimfire, the goal is straightforward: a comfortable, easy-to-find grip without an unnecessarily aggressive surface.
With over six years of CZ rimfire experience, Pete's Pillars makes practical upgrades that feel at home on a working rifle. We CNC-machine this knob from solid billet aluminum in the USA, finish it in black, and use M6x1 internal threads for the compatible factory CZ 455 and CZ 457 bolt handles and other appropriately threaded applications.
An XL Profile with Purpose
The enlarged shape gives your fingers more to grab, while the groove pattern adds a defined contact point without turning the entire knob into coarse knurling. Smooth transitions between the grooves make it comfortable for repeated bolt manipulation and easy to wipe clean after a dusty range day. The lightweight aluminum construction and restrained black finish pair well with either factory furniture or a modern competition chassis.
If you've been looking at aftermarket options such as the Area 419 bolt knob, the PPFGL deserves a look on its own merits. This is Pete's Pillars' XL finger-groove design, built around its own contour, gripping feel, and USA-made billet construction. It's about choosing the shape you prefer, not claiming every shooter wants the same knob.
M6x1 Fitment: CZ, Bergara, and More
The PPFGL fits compatible CZ 455 and CZ 457 bolt handles with M6x1 threads. It also fits other bolt handles using that same M6x1 thread specification, including compatible Bergara rifles. Thread size is the deciding factor, so confirm your existing handle uses M6x1 before ordering; don't assume every rifle or every model year shares the same threads.

Updating the bolt handle on a CZ 457? Our PP457LCI Extended Stainless Steel Cocking Indicator is another practical bolt-area upgrade, while the PP457FP OEM-Style Firing Pin and PP45715 15 MOA Picatinny Rail provide other useful ways to personalize the rifle with USA-made Pete's Pillars components.
If your project is going beyond bolt controls, take a look at the MDT Field Stock or KRG Bravo for traditional stock-like ergonomics. For a more competition-focused CZ 457, we also carry the MDT LSS Gen3 Competitor, MDT ACC Premier Gen2, and flagship MDT ACC Elite. These are CZ 457 stock and chassis choices; check individual fitment for other rifle platforms.

Frequently Asked Questions
Thread fit, CZ and Bergara compatibility, grip feel, and common bolt-knob questions.
Will this fit my CZ 455 or CZ 457?
Yes, if your bolt handle has the standard M6x1 threaded knob connection. That's the application this knob is made for. If your handle has been replaced or modified, check the threads before ordering.
Will it fit a Bergara bolt handle?
Yes, on Bergara handles threaded M6x1. It's the thread size that matters, not the name stamped on the rifle. Some configurations differ, so check your handle before ordering rather than assuming every Bergara uses the same thread.
What makes the XL finger-groove shape different from a round knob?
It gives your fingers a larger, more defined place to land. The grooves and subtle texture help you find a comfortable grip without the feel of heavy, sharp knurling. If you've always found a small factory knob a little awkward, that's the reason to consider this one.
Is the PPFGL aluminum or steel?
It's CNC-machined billet aluminum with a black finish, made here in the USA. You get the larger XL shape without the weight of a similarly sized solid-steel knob.
Does the PPFGL replace the whole bolt handle?
No, it's the knob only. It threads onto a compatible M6x1 bolt handle; the handle itself is not included.
Is this a good choice for a hunting rifle or a match rifle?
Both. The extra gripping area is useful whether you're at the bench, wearing gloves in the field, or running a stage in NRL22 or PRS Rimfire. The best bolt knob is one that feels right to you, and this is our XL finger-groove option.
