Trigger Spring Kit for CZ 452 & 455 rifles

This is a basic set of two springs designed to fit the trigger mechanism of CZ 452 and CZ 455 rimfire rifles only. They are NOT suitable for the CZ 457 or any other models! We have run out of the brass tubes which we used to supply with three springs but whilst these were useful with the CZ 452 rifles we found their use in the CZ 455 rifles led to a dangerously light sear engagement which was patently unsafe!  So, by providing the springs alone we can still offer a lighter trigger pull in these rimfire rifles at reduced cost. The two springs should give approximate trigger pull weights of around 1.0 lb or 1.75 – 2.0 lbs  so it may well be worth trying each spring in your own rifle followed by safety testing of the trigger! A leaflet giving detailed instructions come with every spring kit.
