Picatinny rails for CZ models

This collection contains Picatinny rails for CZ and Brno rifles. Most of them are machined from steel by JK-N in the Czech Republic. CZ, Contessa and Toni System also make rails here.

Rails by CZ model

• CZ 457: the widest choice. Steel rails from JK-N and Contessa, aluminium rails from CZ and Toni System. JK-N makes them flat or with 15, 20, 25 or 35 MOA, and also for left-handed rifles. CZ makes a flat and a 25 MOA aluminium rail. See Picatinny rails for CZ 457.
• CZ 452 and CZ 455: a Contessa steel rail that fits both. See Picatinny rails for CZ 452 and Picatinny rails for CZ 455.
• CZ 550 and CZ 557: JK-N rails for Short Action and Long Action variants. See Picatinny rails for CZ 550 and Picatinny rails for CZ 557.
• CZ 600: JK-N rails for short, medium and long upper receivers, and a medium version with 25 MOA. The product page lists the CZ 600 models for each size. See Picatinny rails for CZ 600.
• Brno ZKM 451, 452 and 456: JK-N rails for a 16 mm dovetail, and a rail for the ZKM 452 with an 11 mm dovetail. See Picatinny rails for ZKM 451, Picatinny rails for ZKM 452 and Picatinny rails for ZKM 456.

MOA angle

A rail marked 15, 20, 25 or 35 MOA is angled forward. The angle adds elevation, so you can zero at long distance without running out of scope adjustment. A rail without MOA in the title is flat (0 MOA), the standard choice for normal distances.

All CZ and Brno rails at a glance

Every rail in this collection with its versions and maker. A rail with no MOA in the version is flat.

Left-handed CZ 457

JK-N makes the CZ 457 rail also for left-handed rifles, flat or with 25 MOA. A right-handed rail does not fit a left-handed receiver.

Brno ZKM: 11 or 16 mm

The Brno ZKM 452 was made with an 11 mm and a 16 mm dovetail on the receiver. The rail clamps on this dovetail, so it must match. The ZKM 451 and ZKM 456 rails are for the 16 mm dovetail.

CZ 600 receiver sizes

The CZ 600 has short, medium and long upper receivers, depending on the model and caliber. The rail must match the receiver size. The product page of each CZ 600 rail lists the models it fits.

Steel or aluminium

Steel rails are robust. Aluminium rails save weight. For the CZ 457 you can choose both.

A Picatinny rail is a scope base screwed to the receiver. It takes Picatinny scope rings, scope mounts and other optics. Most Weaver rings fit it too. For rings, see Scope rings for Picatinny base. For all rails, see Picatinny rails.

For scope rings for CZ, see Scope rings for CZ models.

Frequently asked questions

Can I install the rail on my CZ myself?

Yes, no gunsmith is needed. Clean the receiver and the screws, put a drop of threadlocker on each screw and tighten them evenly to the torque given by the maker.

Which scope rings fit the rail?

Any Picatinny rings, and most Weaver rings. Choose the ring diameter by the main tube of your scope. See Scope rings for Picatinny base.

Which rail fits my CZ 600?

It depends on the size of the upper receiver: short, medium or long. Each CZ 600 rail lists the models it fits in its description.

Which rail fits my Brno ZKM 452?

Measure the dovetail on your receiver and take the rail for the 11 mm or the 16 mm dovetail.
