The CZ 457 triggerThe first thing you notice is that it looks like nothing you've ever seen before on a CZ rimfire rifle. Although fully adjustable it could have made with better adjustments in mind, however, we'll do our best to make due with what we go.
So in the kit you found a spring, and a nylon block with a hole in it. The punch shown in the picture is not included in the kit but is available on the website. What is that block for? well the block is to support the trigger assembly while you remove the pivot pin, which when aligned properly will drop down into that hole in the block. |
Remove the bolt from the action and then remove the trigger pull adjustment bolt and nut, nothing needs to be done to the other 2 adjustment screws. Slide the support block under the trigger assembly to support it during pivot pin removal. The pivot pin is in there pretty firm, it takes a good solid square hit on the punch to get it started, from there it starts to move fairly easy, ensure that the hold in the block is lined up with the pin so that it will slide out of the trigger while the block still supports the trigger assembly.
