Description

The YODAVE PLUS 10 Striker Spring is an aftermarket upgrade designed for CZ rimfire rifles (452, 453, 455, 513). It replaces the factory firing pin (striker) spring with a higher power (+10%) spring, improving ignition reliability—especially when using harder-rim or inconsistent rimfire ammunition.
This upgrade is commonly paired with trigger spring kits to create a more refined shooting system, ensuring both lighter trigger pull and consistent primer strikes.
