AREA 419 FINGER GROOVE BOLT KNOB – CZ 457 & BERGARA – M6x1
A Better Grip on Every Bolt Cycle.
The Area 419 Finger Groove Bolt Knob is CNC-machined from 6061-T6 aluminum with a contoured finger groove between two knurled gripping surfaces, finished in flat black anodize. It threads onto factory M6x1 bolt handles on the CZ 457 and compatible Bergara rifles for faster, more positive bolt manipulation. Made in USA.
A small factory bolt knob is easy to fumble, especially in positional shooting, with gloves or on the clock. An oversized finger-groove knob gives your hand a natural place to land, so you can run the bolt quickly without breaking position. It's one of the simplest upgrades you can make to a CZ 457, and one you'll feel on every shot.
Or Choose a Pete's Pillars Knob, Made for the CZ 457.
We've spent more than six years building and supporting CZ rimfire rifles, and we design and machine our own CZ 455/457 bolt knobs in the USA. If you like the finger-groove concept, start with our XL Finger Groove knob, or pick a slimmer profile below.

Frequently Asked Questions
Fit, thread size and choosing the right CZ 457 bolt knob.
Will it fit my CZ 457?
It threads onto factory CZ 457 bolt handles with M6x1 threads. Verify your bolt handle thread before ordering.
Which Bergara rifles does it fit?
It fits Bergara models that use M6x1 bolt knob threads. Check your rifle's thread size, as well as scope and stock clearance, before ordering.
What's the difference between this and the Pete's Pillars XL Finger Groove Knob?
Both offer a finger-groove profile with knurled grip surfaces. The Pete's Pillars Knurled Finger Groove XL Bolt Knob is designed and machined by Pete's Pillars specifically for the CZ 455/457, in an XL size for maximum grip.
Do you offer slimmer bolt knobs?
Yes. Our slim CZ 457 knobs include the Slim Knurled Grooved, Slim Smooth Grooved, Slim Spiral Knurled, Slim Spiral Smooth and Slim Helix Knurled, all Made in USA.
Will a larger knob hit my scope?
Clearance depends on your scope, rings and rail height. Larger knobs can contact low-mounted eyepieces, so check clearance with the bolt fully open.
What else should I upgrade on my CZ 457 bolt?
Our PP457LCI Cocking Indicator, PP457FP-T Firing Pin and PP457ES Extractor Set make a complete bolt refresh.
How do I install it?
Unscrew the factory knob, then thread the new knob onto the M6x1 bolt handle and snug it by hand. A drop of removable thread locker can help keep it in place.
Small Change. Big Impact. Pete's Pillars.
