Pete's Pillars CZ 455/457 26" Stainless Steel Match Sporter Barrel – 1/2-28 Threaded
The Pete's Pillars PP457-26SST is a USA-made, 26-inch stainless steel match barrel designed for CZ 455 and CZ 457 bolt-action rimfire rifles. Featuring our proprietary .22 LR match chamber, traditional sporter-taper contour, and 1/2-28 threaded muzzle, this barrel delivers precision-focused construction without the expense of a fully custom barrel.
Designed for shooters who appreciate the classic handling and appearance of their CZ rimfire rifles, the PP457-26SST offers an attractive alternative to expensive custom barrels and difficult-to-source factory CZ MTR replacements. Its sporter contour makes it particularly appealing for owners retaining their original walnut or synthetic sporting stocks.
Proprietary Match Chamber – Precision Without the Custom Price
At the heart of the PP457-26SST is the Pete's Pillars proprietary .22 LR match chamber, developed for shooters seeking improved precision from their CZ rimfire rifles.
Combined with a traditional 1:16 rifling twist and recessed muzzle crown, this chamber provides a precision-focused foundation for use with quality .22 LR ammunition.
Unlike the heavier factory CZ Varmint MTR barrel, our sporter-taper design preserves the familiar proportions and handling characteristics of traditional CZ sporting rifles.
Important: This is a Pete's Pillars aftermarket barrel with our own match chamber, not a factory CZ MTR barrel. Accuracy depends on ammunition selection, individual rifle characteristics, and proper fitment.
26" Stainless Steel Sporter-Taper Construction
The 26-inch stainless steel barrel combines a classic long-barrel appearance with modern precision-focused manufacturing. Its sporter contour is intended for shooters who prefer their existing sporting stock rather than converting to a heavy competition barrel and chassis system.
- 26" Barrel Length: Traditional long-barrel configuration for CZ rimfire rifles.

- Proprietary Match Chamber: Pete's Pillars precision-focused .22 LR chamber design.
- 1:16 Twist Rate: Traditional rifling twist for .22 LR ammunition.

Keep the Classic CZ Sporter Rifle
One of the biggest advantages of the PP457-26SST is the ability to upgrade barrel quality while retaining the stock and overall appearance that made the CZ 455 and CZ 457 so appealing in the first place.
Many shooters prefer the warmth and handling of a traditional walnut stock over the weight and appearance of a modern competition chassis. The PP457-26SST is intended for those owners who want a quality replacement barrel without fundamentally changing their rifle.
Its sporter contour is designed to accommodate many original CZ sporter barrel channels, although individual stock dimensions and barrel clearance should always be verified.
CZ 455 & CZ 457 Barrel Compatibility
The PP457-26SST is designed for compatible CZ 455 and CZ 457 rifles chambered in .22 Long Rifle.
Most compatible actions do not require additional barrel shims, although individual action and barrel tenon tolerances vary. Shimming remains an optional fitment consideration rather than a universal requirement.
Fitment Note: Confirm barrel tenon fit, proper headspace, and stock-channel clearance before use. Professional gunsmith inspection and installation are recommended. This barrel is intended for .22 LR, not .17 HMR or .22 WMR.
Complete Your CZ 455 / 457 Sporter Rifle
A precision barrel is only one part of a well-assembled sporting rifle. Proper action bedding, consistent stock support, and dependable optics mounting complement a quality barrel while preserving the traditional character of your CZ rimfire.

Bedding Compatibility: CZ 455 and CZ 457 pillar configurations are rifle-specific. Select the correct pillar set for your action and verify adequate stock material before installation.
Prefer an Unthreaded Barrel?
For shooters who prefer a clean, traditional muzzle without threads, Pete's Pillars also offers the 26" Stainless Steel Match Sporter Barrel – PP457-26S.
Both configurations retain the same general sporter-barrel concept and proprietary match chamber. The PP457-26SST includes 1/2-28 muzzle threads, while the PP457-26S offers a traditional unthreaded configuration.
