LILJA | PREMIUM .17 HMR CZ RIMFIRE BARRELS
One Grade. Lilja’s Best. Built for the .17 HMR.
Lilja doesn’t divide its barrels into good, better, and best. It makes one grade: its best. This 21-inch .17 HMR match barrel brings Lilja’s hand-lapped stainless barrelmaking to the CZ 455 and CZ 457, with a substantial .900-inch straight profile and a caliber-correct 1:9 twist. Get it from Pete’s Pillars, an authorized Lilja dealer with over six years of CZ rimfire experience.
The .17 HMR has a devoted following for good reason: it makes a lively, flat-shooting rimfire for varmints, predators of appropriate size, and precision-minded days at the range. If your CZ 455 or CZ 457 is the rifle you reach for when the targets are small and the shots matter, a Lilja barrel is a premium place to start the build.
Lilja manufactures its barrels from rifle-barrel-quality stainless steel, with drilling, reaming, rifling, stress-relieving heat treatment, and hand-lapping performed as part of its process. That attention to the bore—not an inflated accuracy promise—is why Lilja has become a name precision rifle shooters recognize. The 21-inch length and .900-inch straight profile give this .17 HMR model a substantial, purpose-built presence.
21 Inches of Lilja Craftsmanship. 1:9 Twist for .17 HMR.
This is the 21-inch, .17 HMR version, not the 1:16-twist .22 LR barrel. Its 1:9 rifling twist is the appropriate specification for this .17-caliber configuration. Lilja’s broader rimfire line is built around precision chambering and carefully finished bores, making this a serious choice for a custom varmint rifle or a refined CZ rimfire project.
Owners of the CZ 457 Varmint will recognize the appeal of a heavy-profile barrel. Shooters familiar with the Varmint MTR also know how central barrel quality is to a precision rimfire build, though the factory MTR is a .22 LR configuration. This .900-inch straight-profile .17 HMR barrel is its own specification; barrel-channel clearance and the rifle’s caliber configuration matter more than the name on the original stock.
Considering aftermarket options such as L3i CZ 457 barrels? Lilja offers a distinctive answer built on its own machining, heat-treatment, and hand-lapping tradition. If you prefer to stay with .22 LR, browse the separate Lilja 21-inch .22 LR Match Barrel rather than confusing the two chamberings.
Build Around Lilja. Finish It with Pete’s Pillars.
A premium barrel deserves equally thoughtful supporting parts. Pete’s Pillars manufactures the PP45748 Stainless Barrel Set Screws for CZ 455/457 hardware maintenance. For compatible CZ bolt assemblies, our PP457SP2 Gen 2 Extractor & Holder Spring is another useful piece of the build. CZ 457 shooters can also explore our PP457FP-T Reshaped-Tip Firing Pin and PP457LCI Extended Stainless Steel Cocking Indicator—small American-made components that reflect the same attention to detail.
The trigger deserves consideration, too. Timney and JARD are established replacement-trigger names in the CZ 457 aftermarket. Prefer to retain the original trigger assembly? Pete’s Pillars offers 8 oz and 12 oz CZ 457 trigger springs for properly tuned factory triggers. Choose the configuration that suits your shooting and your gunsmith’s evaluation.
For a premium CZ 457 competition-style build, see the MDT LSS Gen3 Competitor, MDT ACC Premier Gen2, and flagship MDT ACC Elite. Each offers a serious chassis foundation; confirm the selected configuration clears this barrel’s .900-inch profile. These are CZ 457 chassis options, not implied CZ 455 stock replacements.
Complete the optics setup with our Pete’s Pillars PP45715 15 MOA Picatinny Rail or the Area 419 CZ 457 30 MOA Scope Rail with integrated level. Both are available from Pete’s Pillars for CZ 457 receiver mounting. The best rail depends on your optic and the elevation range you expect to use.

Frequently Asked Questions
Straight answers about .17 HMR, twist rate, the .900-inch profile, and your CZ 455/457 build.
Is this the .17 HMR barrel or the .22 LR version?
This is the .17 HMR barrel. It is 21 inches long with a .900-inch straight profile and a 1:9 twist. The Lilja .22 LR models are separate barrels with different chambering and twist specifications.
Will it fit my CZ 455 or CZ 457?
It is sold for CZ 455 and CZ 457 rifles in an appropriate .17 HMR configuration. The barrel alone does not turn a .22 LR setup into a complete .17 HMR rifle. Match the chambering and the rest of the rifle’s caliber-specific components.
Can I use it with a CZ 457 Varmint or Varmint MTR stock?
The key question is barrel clearance. This Lilja has a .900-inch straight profile, which is not necessarily the contour of your original barrel. A Varmint stock may need more room, and the Varmint MTR is originally a .22 LR rifle. Check the actual channel and rifle configuration before choosing this .17 HMR barrel.
Why does this barrel use a 1:9 twist?
Because it is chambered for .17 HMR. The correct twist listed for this model is 1 turn in 9 inches, not the 1:16 used on the Lilja .22 LR straight-profile models.
What makes a Lilja barrel a premium choice?
Lilja makes one grade of barrel: its best. Its stainless barrels are drilled, reamed, rifled, stress-relieved, and hand-lapped. The craftsmanship and attention to bore uniformity are the reason shooters seek out Lilja for precision builds.
Do I need to change my trigger or bolt parts to buy this barrel?
Not automatically. Plenty of shooters start with the barrel and refine the rest of the rifle later. If you are updating the CZ 457 bolt or trigger too, Pete’s Pillars carries the firing pins, extractor springs, and trigger springs to support that work.
Is this a good choice for a CZ 457 varmint rifle?
Absolutely, if .17 HMR is the caliber you want. A 21-inch Lilja match barrel with a substantial .900-inch profile is a premium foundation for a varmint-focused CZ build. Choose the setup around your shooting needs, caliber-specific parts, and barrel clearance.
