PETE'S PILLARS CZ 457 COMPETITION PILLAR BEDDING | MADE IN USA
A Better Bedding Foundation Starts Here.
Starting with billet aircraft-grade aluminum, we machine our CZ 457 Competition Pillar Kit with Epoxy right here in the USA. You get the profiled pillars and premium bedding epoxy, a strong foundation for a solid, consistent connection between your action and stock.
One of the most important details in a traditional rifle stock is also one of the easiest to overlook: the support around the action screws. A properly fitted pillar gives the action a rigid place to sit, helps keep the stock from compressing, and helps the rifle go back together the same way every time it's serviced. Use it for: CZ 457 rimfire rifles in wood, laminate or composite stocks that need custom pillar bedding, from sporting rifles to dedicated precision rimfire builds.
Built to Be Part of the Stock.
Each pillar starts as a solid piece of billet aircraft-grade aluminum and is machined to a shape made just for the CZ 457. Flat, square-cut ends give the action a solid place to bear, and the grooves around the outside grip the bedding epoxy once it cures, so the pillar becomes part of the stock. Every pillar is supplied a little longer than it needs to be so you can fit it to your own stock. This is a purpose-made bedding part, not a generic aluminum spacer.
The included premium bedding epoxy covers the rest of the materials. We source from established products such as Devcon, JB Weld or a comparable premium bedding compound, and the specific brand may vary. The result is a practical kit for shooters and gunsmiths who like to choose the finishing hardware for the exact rifle they're working on.
Complete Your Bedding Project.
The pillars and epoxy are the foundation. Helper hardware and finished action screws are separate choices with different jobs, and both are worth a look while you plan your CZ 457 stock project. Recommended companion hardware, each sold separately.

Our profiled Competition pillars are designed for the CZ 457 action family, including .22 LR, .22 WMR and .17 HMR variants. Common rifle models to evaluate include the American, Lux, Varmint, Pro Varmint, Scout, AT-ONE and Royal, plus compatible aftermarket or custom stocks. The action is the common starting point, but the stock's available material and existing bedding determine whether the 1/2″ Competition size is the right choice.
Already have factory bedding pillars? Certain CZ 457 Varmint MTR walnut stocks come with pillars installed, and many aluminum chassis use their own engineered bedding structures. Check what is already in the stock before purchasing another pillar set.

Frequently Asked Questions
Compatibility, included materials, companion hardware and choosing your CZ 457 bedding components.
What does pillar bedding do for a CZ 457?
Properly fitted pillars create a rigid interface around the action screw mounting points, helping reduce compression of compatible stock materials and support consistent action seating. Bedding does not guarantee a particular accuracy improvement.
What comes in this Competition kit with epoxy?
The kit includes CZ 457-specific profiled Competition aluminum pillars and premium bedding epoxy. Epoxy brand may vary; we select from trusted options such as Devcon, JB Weld or comparable compounds. Action screws and temporary bedding helper hardware are your choice, sold separately.
Which companion hardware should I order?
For CZ 457 bedding projects, pair this kit with our M5 × 0.8 Bedding Helper Hardware Kit for the bedding process. Our PP457AS extra-length action screw set is a separate option for the finished rifle. They serve different purposes and neither is included.
Which CZ 457 stock inlets can use these pillars?
The Competition profile is intended for compatible CZ 457 stocks, including appropriate American, Lux, Varmint, Pro Varmint, AT-ONE, Scout and other factory or aftermarket stock inlets. These models share the CZ 457 action family, but stock construction, existing bedding and available material determine suitability. Our parts fit most CZ 457 rifles. We machine to very tight tolerances, so every now and then a production rifle with factory tolerance stack-up falls a little outside that range, and a stock may need individual fitting.
Are installation instructions included?
No. Printed installation instructions are not included. With basic tools, patience and thorough preparation, pillar bedding is a project many rifle owners can tackle themselves. Numerous online writeups and YouTube videos walk through the general process and are useful references before you start. Each stock may need individual fitting.
Competition vs. SlimLine: which should I choose?
Competition pillars use a nominal 1/2″ outside diameter for stocks with plenty of material. CZ 457 SlimLine pillars use a smaller 7/16″ outside diameter for narrower stock inlets. Both use profiled, USA-made aluminum construction.
Are these the same as a chassis bedding system?
No. The Competition pillars are intended for suitable traditional and compatible aftermarket stocks requiring custom pillar bedding. Most modern aluminum chassis, including MDT and KRG designs with integrated bedding surfaces, generally do not need a conventional pillar kit.
