CZ 457 scope bases [picatinny rails]

One option for installing a riflescope on a CZ 457 is using mounting rings for a Picatinny rail. To use them, you cannot do without the Picatinny rail itself.

 

In this category, you will find Picatinny rails for the CZ 457 in .22 LR as well as in magnum calibers.,

Mounting rings for a Picatinny rail are available in many variants, allowing you to choose a custom-tailored solution. The advantages include:

Most CZ 457 models do not come with an integrated Picatinny rail from the factory. Fortunately, it can be easily purchased and retrofitted.

When to get a Picatinny rail

• want quick-detach (QD) accessories for fast and convenient optics changes or for moving a riflescope to another firearm
• own multiple firearms
• are looking for maximum variability
• want additional tactical accessories
• shoot at longer distances and therefore need to address inclination (MOA rails)
• enjoy the versatility of the mounting system and like upgrading their firearm with various accessories

When considering whether to acquire a Picatinny rail, take the following factors into account:

• The Picatinny rail increases the height of the riflescope axis above the barrel.
• A more complex mechanism naturally carries the risk of a joint loosening, potentially resulting in a loss of zero.
• Higher overall weight of the entire system.

Rails are manufactured from either aluminum or steel.

 

Aluminum rails have a lower weight, but be careful during installation—ensure you do not exceed the recommended tightening torque (1 Nm). As a softer material, aluminum is more prone to deformation.

 

Steel rails can handle a higher tightening torque (2–2.5 Nm). Their relative disadvantage is higher weight and tighter tolerances—with steel rails, it is sometimes necessary to use a bit more force during installation.

Can I install a Picatinny rail myself?
