Kozap Slip-On QR Base, CZ 550

• Quick-release base design: The slip-on QR format lets the mount be removed and refitted more easily than a fixed base, which is useful for rifles that alternate between scoped and open-sight use.
• Rifle-specific fit: Built for the CZ 550 platform and related 19 mm dovetail actions, this base gives a more secure and correct interface than a universal mounting solution.
• Compatible with KOZAP Ø 8 mm interface: It serves as the correct lower half for KOZAP’s matching upper interface, making it easier to build a mount around the scope rings or top section already required.
• Steel-minded hunting application: A dedicated base for traditional hunting rifles helps keep the optic seated consistently under field recoil and repeated handling.
• Made in the Czech Republic: Czech production suits the product’s intended use on Brno and CZ rifles, with a design approach centered on established Central European hunting firearms.

About the Kozap Bases Series

Kozap Bases is KOZAP’s rifle-specific base line for shooters who need a mounting foundation matched to the action rather than a generic rail. In the company’s mount catalog, these bases sit alongside complete CLASSIC and ALFA mounting solutions and are intended for users who want to assemble the final scope mount around a particular rifle and optic combination. A key characteristic of the series is its focus on model-specific compatibility, with versions listed for rifles such as the CZ 512, CZ 527, Brno 802, Brno Effect and Brno ZKM 611.

The series reflects KOZAP’s practical approach to hunting optics mounting: some models are offered as bases only, allowing the shooter to add the appropriate upper parts or rings separately, while several rifle families are supported in both one-piece and two-piece configurations. Within the broader KOZAP range, the bases are part of a system built around familiar Central European sporting rifles and established dovetail mounting standards. That makes the series especially relevant for hunters and traditional rifle owners who want a mounting solution tailored to the firearm’s receiver geometry instead of adapting the rifle to a universal platform.

About the Kozap Slip-On QR Base, CZ 550

The Kozap Slip-On QR Base, CZ 550 is a dedicated lower mounting component for shooters using a CZ 550-pattern rifle or related Brno and CZ actions with a 19 mm dovetail. Its role is straightforward but important: it provides the correct rifle-side interface for a detachable scope-mount setup, so the optic system starts with a base shaped for the receiver it is going onto. That matters on hunting rifles, where a poor fit at the base can affect stability, alignment and repeatability more than the upper mount design suggests.

This model is intended for use with the KOZAP Ø 8 mm interface, so it fits into the brand’s modular mounting system rather than acting as a universal standalone rail. In practice, that gives the user a cleaner route to building a rifle-specific quick-release arrangement around compatible KOZAP upper parts. The quick-release slip-on concept is useful for rifles that may be carried with iron sights, stored with the optic removed, or used with different sighting setups depending on the hunt. Because the base is dedicated to the CZ 550 family and several related Brno/CZ rifles, it suits owners of classic Central European sporting rifles who want a mounting solution that respects the original receiver format instead of replacing it with a bulkier rail system.

Finished in black and made in the Czech Republic, this base is best understood as a purpose-built foundation for traditional hunting optics mounting: compact, rifle-specific and designed to integrate with KOZAP’s established mount ecosystem.
