    On my AR I have a trigger that is very responsive and there is no break point when I squeeze.

    With the CZ there is that hard tension right before I squeeze the trigger all of the way.

    Any recommendations.

    Thanks all.

    The CZ527 trigger is very adjustable, you should be able to get it set the way you want it. The owners manual has the instructions on doing that.

    Are you using the set trigger function (pushing the trigger forward before each shot)?

    When you say CZ 223, do you mean the 527, the 600, one of the 805 Bren 2 variants or some other model I haven't heard of yet?

    OK, just to be sure, you know the trigger is a single set right? You push it forward to set?

    Is that on all models of the 527? I think only some have the set trigger.

    I have a copy of an article titled "From Hornet to Hornet or Simply Small Mausers: CZ527" which says the single set trigger was introduced into serial production in 1992 along with the .223 chambering and the 527 designation.
    The 527 was the successor to the ZKB680 Fox, which was available in .22 Hornet and .222 Remington. The Fox was itself a replacement for the ZKW465 in .22 Hornet only. Both models preceding the 527 were offered with a 'German' double set trigger as an option.

    I have no idea whether this article is the last word on the subject, but if I recall correctly it was in an English-language publication from CZ itself.

    However at one point the factory user manual uses the phrase "whether there is a mounted set trigger or not", so maybe ...
    http://pdf.textfiles.com/manuals/FIREARMS/cz527.pdf


    Rifle Basix offers a non-set trigger for the 527, which may suggest that it wasn't a typical factory option:
    https://riflebasix.com/product/ceska-zbrojovka-527-550-trigger-cz-527/


    Here's what they have to say at the CZ website: https://cz-usa.com/the-cz-single-set-trigger-system/


    I would be genuinely curious to know whether anyone on this forum owns a CZ 527 that lacks the single set trigger. All three of mine have it.

    I have 6 - 527’s; a carbine, an American, and 4 varmints. All have a set trigger. That said, I’ve adjusted the triggers for a lighter pull and don’t use the set feature. Adjusting the triggers usually takes multiple attempts. Sometimes I get it right on the first or second try, and other times it seems like I’ll never get it, but I’ll keep at it until I’m happy.

    Once it get it adjusted I find the CZ trigger to be one of the best at any price point.

    I agree with this exactly. I find the set trigger to have too much over travel. I have adjusted mine to where I want it and don't use the set trigger. They can be adjusted for a nice clean break with very little pre- and post- travel.

    I guess it is matter of personal taste - mine is a s good as any gun I have shot except maybe the SAKO's....

    That's a very cool rifle!

    I wonder whether CZ modified their set trigger design for this, developed a second, completely different trigger mechanism from scratch, or subcontracted an aftermarket trigger and fitted it at the factory. I had no luck finding a photo of it to satisfy my curiosity.

    CZUSA just shows the single set trigger in their 527 parts catalog:

    All 5 of my 527s have set triggers don't feel the need to tinker with the innards.

    MR. WICK, the photo that you posted a while back was of a 527 that would have the standard CZ Single Set Trigger (SST). You should only need to spend some time properly and carefully adjusting it, and it should be good.

    As others have said, the Varmint MTR, which came out late in the 527's production run, did NOT have the classic CZ SST. Instead, the MTR had a single adjustable trigger, apparently like the one on the 557. As someone mentioned, the trigger blade is more curved on the new style non-SST trigger. It resembles the blade on the 527 and 550 SST up until about 2006 or so. The 453 used this same blade shape as well. After about 2006 or so they switched the 527s and 550s trigger shape to the less curved trigger that you see on the majority of those guns. From what I've read (I haven't owned an MTR or a 557), those triggers aren't designed to be adjusted as light as the classic SST can.

    I have 8 CZs with the SST of the 453/527/550 style. I USED to keep the non-set mode adjusted as light as it would safely go, and kept the Set feature disabled. A few years ago, I spent some time on my 527 Varmint to get the Set mode adjusted down to a few ounces, and realized THAT is how I want all of mine adjusted because it tightened up my groups by a quarter inch or so. I have all of mine adjusted VERY light in set mode and IMO, the trigger is excellent. I used to not like the overtravel in Set mode (which is why I used the non-set mode), but some .2" - .3" 100 yard groups quickly make me not notice the overtravel. IME, a LIGHT, highly predictable trigger is an essential component for shooting one's best groups or maximum accuracy. :)

    NOTE: If you want the Set mode REALLY light, you should be prepared for a little bit of trial-and-error before you get it just perfect after everything's all tightened back down. Get it right, and it's as if (for me anyway) you can just "think" that you want the gun to fire at a precise instant, and it does.

    My CZ trigger is crisp regardless of using the "set" feature. I guess the next step is to try that feature or adjust as needed.

    This.

    My 453 and 527 both have set triggers. For me, that’s one of the keys to accuracy
