Thread: Trigger upgrade on cz452

    Trigger upgrade on cz452

    After taking the stock off my cz452 to adjust the trigger and finding out it wasn't easily adjustable I have ordered a trigger kit from rimfire magic.

    Has anyone upgraded the trigger on a cz and did it make much improvement?

    I've had the 10 Rimfiremagic kit in my CZ since very shortly after I bought the rifle. The kit goes in quite easily, just a couple of pins to drift out. As has been said, err on the side of caution with which of the springs and bushings you use. But it makes a better trigger, removing the awful creep from the original.

    Sounds good, it never really was a problem all summer last year but after having a good winter using the centre fire that's light and adjustable it's very noticeable once I picked it up the other night.

    i have measured it and currently breaking at 4lb so want to take it lighter hopefully.

    i don't like them really light as most shooting is done in the field.

    Does the kit cone with an array of springs then?

    all my shooting is also done in the field, and I got given mine from a very kind member on here, but there was an array of springs and shims.... and it worked well, just takes time to get it as you like it.

    also be carful when tapping out the pins,

    i had a lad here last week and he had broken one of the shoulders where the trigger is held on, to heavy handed and is now looking at a new rifle,?

    and as mentioned to light and it can be very dangerous

    this is the area he hit way to hard and with the wrong sized punch,

    You should be able to get away with just a spring change but carry out bump tests untill you are satisfied with the safety aspect.

    I fitted a rimfire magic kit to my CZ455 last month and its made a big diffrence. I used the middle spring which they say is 1.7lb which is loads better than the stock but not too light.

    I spent a good while tapping it and cycling the bolt and safety just to check it did not fire it's self.

    Well worth doing

    Enjoy

    Trigger blade is about 40 from Edgar's. if they can be bothered to get one.
    Best answer is just change the complete trigger for a Timney, that way you get a decent trigger that doesn't rely on any CZ parts.
