About

What it is, and why it matters

Copy a link to this section

The CZ 455 is a Czech bolt-action rimfire rifle introduced in 2010 as the modular successor to the long-running CZ 452. Its defining feature is a swappable barrel system held by twin set-screws that lets a single action accept .22 LR, .22 WMR, or .17 HMR barrels without specialized tools. Stocks are also fully interchangeable across the 455 product family. Most models were discontinued in 2018 and replaced by the CZ 457, which retained backward compatibility with most 455 magazines and barrels.

The CZ 455 was the first rimfire to make caliber switching as easy as a screwdriver swap, letting the same rifle plink with .22 LR in the morning and varmint hunt with .17 HMR by lunchtime. Its modularity and accuracy made it a favorite trainer for centerfire bolt-gun shooters on a budget.

All barrels are cold hammer-forged. The receiver carries an integral 11mm dovetail rail rather than a Picatinny rail.

Trajectory

What the round does downrange

Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.

Studio

Every part that mounts on this, resolved

Not a list the maker typed out: the answer comes from the mounts this firearm exposes and the interface each part needs, so it stays right when either one changes.

  • Every part that mounts on any firearm in the catalogue
  • Interface standards, platforms and fit overrides
  • The same answers through the API and the MCP server

Requires a signed-in GunSpec account on the Studio plan. The answer is computed per part, so it is not part of the public record.
