Warne 1BLM 25mm Med QD Rings Brno CZ
Specifically, the Warne 1BLM 25mm Med QD Rings Brno CZ are steel quick-detach scope rings for a compatible CZ 550 rifle with a 19 mm integral dovetail. In addition, they fit riflescopes with a 1-inch (25.4 mm) main tube and have a matte black finish. As a result, the rings attach directly to the receiver without requiring a separate mounting base.
Warne 1BLM 25mm Med QD Rings Brno CZ
First, Warne’s Maxima rings use a vertically split design to hold the scope securely. Moreover, their steel construction provides a strong mounting interface. Furthermore, the quick-detach levers let you remove the scope assembly when needed. Meanwhile, the indexable lever system lets you reposition the levers for easier access. According to Warne, correctly installed rings return to zero after removal and reattachment. However, always check zero after reinstalling your scope before using the rifle.
Regarding scope fit, these medium-height rings suit a 1-inch tube rather than a 30 mm tube. In addition, Warne lists a maximum objective size of 42 mm. However, actual clearance depends on the scope, barrel and rifle setup. Therefore, check the complete setup before installation.
Compatibility and Related Equipment
First, confirm that your rifle has the compatible 19 mm integral dovetail. Specifically, the product listing identifies the CZ 550. As a result, do not assume that every CZ model uses the same receiver interface. Instead, check your exact rifle model and receiver dimensions before ordering.
Before installation, make sure the firearm is unloaded and follow the manufacturer’s instructions. For the designated bottom screws, Warne specifies a maximum torque of 25 in-lb on dry threads. In addition, do not use thread-locking compound. For the ring-top screws, follow the scope manufacturer’s torque recommendation; however, never exceed 25 in-lb. Finally, tighten the quick-detach levers by hand, without using a tool to force them tighter.
For compatible mounting options, see the Rings & Bases category. For full product details, consult the official Warne 1BLM product page.
