CZ 452 questions!!!

[bug_eyedmonster]

So I bought a CZ 452 in .17HMR and it's in jail. I'm picking it up tomorrow.

1. The other day, I was ordering stuff for my girlfriend's AR build, and saw that Timney made a trigger kit for my CZ. Being a compulsive shopper (especially online), I bought one. The only reason why is because the trigger on my rifle REALLY sucks. I saw the spring kits and weird packs of parts you can order, but I'm by no means a gunsmith, and I don't feel like bothering mine to put this together. Well, after placing the order, I went on google just to see if there were any special things I needed to do to install this drop-in trigger kit. Apparently, I have to channel the stock where the trigger sits to fit the larger assembly.

Now, the question is, should I return it and order the bag-o-parts, or should I just stop being such a cry baby and bust out the file set? My major concern is that if I cut too much, I'll have to buy a new stock.

2. I bought the American model, which does not have a heavy contour barrel. Does anyone make an aftermarket barrel for this gun in .17 HMR? I don't mind, at this point getting another stock because of the stock inletting for the trigger kit, so I might as well go all out.

3. Does anyone that has this rifle have any gripes about this gun? I have talked to a couple of people that have the same rifle, and some have had trigger problems, other have not, but everyone has said the same thing... when shooting the light contoured barrel, they said it does warm up after firing several rounds quickly. I've done the same thing with my other rifles, and never really noticed any changes in accuracy, but is that different with the .17?

Thanks in advance for your help!

I can't speak for the .17, but I own three CZ 452s; a Varmint, and Ultra Lux and a Scout -- all chambered in .22LR.

While I have heard good things about the Timney triggers, I had also read shining reviews of both the YoDave kits and the "PMTJ" (Poor Man's Trigger Job) in the CZ/BRNO section of the forum over on Rimfire Central.

I opted to go with the YoDave kit(s) and have achieved outstanding results on all three of the rifles. No inletting required and relatively easy to install. The hardest part is driving out the trigger pins - and that's not that big of a deal. You don't have to be a gunsmith to do it.

I've got the trigger on my Varmint at right about one pound - no kidding. I have bump-tested the living daylights out of it and it absolutely will not fire unless the trigger is pulled. Zero creep. Absolutely awesome.

I have the Timney trigger in mine and you will not be happy. It has a fault that when the CZ firing pin presses against the trigger it increases the pull weight. It is a bad design. Just get the kit.

Did you have the first version, or the second version? I just want to clarify because I've heard of some issues with the first. I can't bring myself to return it yet... anyway, I'll give it a shot and see what happens.

Did not know there was a first/second version! Mine is the version that sucks. I plan to work with it and the firing pin too get it right.

It is easy to install on the rifle and you don't have to work the stock over to see if it works.

i have 2, CZ 452's with the standard triggers and Brooks 'kits' installed in the triggers that are highly adjustable...why go to another? these triggers, from the factory, (at least the ones i have...they're early 2000 models.) are very good triggers and can be adjusted down to under one pound.

if you opt for triggers below 2 pounds, it's a good idea to have them installed, adjusted and tested by a licensed gunsmith...if you can find one who will.

My new CZ Varmint TH in .17Hmr came through with a very nice trigger. Not a bench rest trigger but an excellent field rifle trigger, crisp. Info on modifying triggers is a big topic on RFC and there are many sticky s with a couple of ways to do it and photos as well. There is no need to go to the Timney.

I have a 453, which has a different trigger than the 452. Even when not in set mode the trigger is ok. It's not great but ok. I have an "American" too (with the light barrel), and it is extremely accurate so far. You should be really happy with the rifle.

The Yodave kit is very adjustable with the spacers and springs without the need to file anything. For how simple it is you'll be amazed how well it works. The cost of 15.00 on ebay vs a Timey is a bit more.

I got a slightly different suggestion, if you dont mind...


Before you do anything, why dont you shoot the gun stock and see how it does? That way you can gauge out whether you really need to be messing with crap.

These guns in stock configuration can do quite excellent.

X-2 I don't know why people feel they have to mod out a new stock gun before they shoot it.
You might just find out that you love it the way it is and will not need to spend money on trigger mods that you could spend on ammo.

[Munny$hot]

Very true you might actually like the stock trigger. I had people shoot mine and damn it to light. Having the lightest trigger is not alwasy the safest. When I set mine up I smacked it on the butt-stock with a rubber mallet to make shure the hammer didn't fall.

I would normally go this route as well, I'm not going to change sometihng out without actually trying it first. The fact is, I was able to check out the rifle in detail and the first thing that I REALLY did not like was the trigger. It's not something that I needed to actually shoot to figure out that I did not like. The reason why I wanted a "drop-in" was because I did not want to modify anything perminantly (other than the stock apparently).

Anyway, I got the rifle a few days ago, and the trigger. It really wasn't bad at all to get working. All in all, it was about an hour's worth of work. Instead of using a dremel or router, I just put a larger drill bit and ran it up and down. Used a fine rat tail file, and then some sand paper, and the stock was done. I'm not sure why some people said it was hard. Once I had the stock off, and the new trigger on the receiver, it was a piece of pie! The Timney kit feels like a DREAM. My stock trigger had about 3/10 of an inch of creep, broke at about 4.3 pounds, and then about another 1/5 inch of over travel. This is why I wanted to get something else... =) I've got the trigger set about just above two pounds, and there is no creep, no over travel (unless you pull harder, but that's to release the bolt). To release the bolt, it actually feels like a totally seperate engagement and is easier than the stock trigger because of a shorter pull.

All in all, I'd rather mess around with the stock than the trigger parts. My concerns with the safety and having to change parts in and out seem more out of my comfort level, but to each his/her own. I'd get the Timney again, but that's just me.

I have a 452 American in 17HMR. Factory stock except for the Yo Dave trigger kit. Go with the Yo Dave kit and you won't be sorry.
