CZ 527 Triggers

[Muir]

In the past I have had no qualms with the triggers on my CZ 527 rifles. I don't use the SST function and I found that after a couple of hundred rounds the standard non-set triggers smoothed up to be very good indeed.

On the latest 527 purchases, however, I've found the triggers increasingly more difficult to tune. Often they have needed some stoning to remove some fairly bad machining marks on the engaging surfaces of the sear. These poor triggers have been a hindrance when shooting off hand so I recently tested a Timney trigger. Once adjusted it was superb. The trigger itself seems to be positioned a little bit more rearward and the pull is a no BS crisp and clean. I had my 6.5 Grendel out tonight and the difference off hand was remarkable. I ordered another for my 7.62x39 as soon as I got in. If your CZ 527 trigger is a bother, look up a Timney. ~Muir

(PS: Timney lists these triggers as being for the CZ 550 and CZ 550 Magnum. I am told that either variant works in the 527)

Just a word of caution not all CZ527 triggers are the same. I know the double set trigger is different as they have the hammer parts on the action. Without checking my 527 not a SST against my 550 which is not sure if they are the same. My trigger isn’t bad, but could probably be better.

Muir I bet you pay a lot less than us for a Timney trigger though!

Do you have the CZ 527 Varmint MTR in 6.5 Grendel and is it this trigger that was in need of improvement? This isn't shown as having a single set trigger, just an adjustable pull from 10 N to 22N. Presumably a Match version would have the best trigger that they could use, or am I being too optimistic?

Rifle Basix have a CZ 527 trigger but this is specifically to replace the single set version. Timney don't list compatibility with the 527, but have a 455 version or the 550 version.

My newish Cz527 17 Hornet had an OK trigger, but it simply wouldn't adjust out that last tiny bit of creep. I'm sure stoning and polishing would have fixed it, but instead I dropped in the the trigger and sear unit from an old scrapped Cz527 in 17 Rem which is much more crisp. The release is so predictable that I don't notice it all. Also this old unit has a far more comfortable curved / hooked style trigger blade that that ensures consistent finger placement.

I might consider the MTR if it didn't come with that butt-ugly, canoe paddle looking stock! Mine is the American with the 24" barrel. My guess is that all the triggers are the same from 527 to 527 regardless of the window dressing. It's odd that Timney doesn't list compatibility with the 527 but I sent them an email and yes, they are the same as the M550. Obviously so because the 550 trigger I ordered dropped into my Grendel without a hitch.~Muir

The last two 527's I've purchased -especially the Grendel- had a trigger pull like five miles of bad road. The machining marks were visible to the naked eye and you could catch them with your fingernail. Really bad. Even stoning left perceptible catches. I have several older rifles -a 223, a Hornet, and a 204 Varmint- that have fine triggers.~Muir

I'm certain that I do but the prices vary widely. The best price I found was 33% less than the average retail with other price listings scattered in between.~Muir

I purchased a Timney trigger with a safety for my Mauser 98 - 338-06 at a very reasonable price of £27.99 on special offer. I think the price was advertised wrongly

But who cares its a wonderfull thing.

Even with my bad math that translates into a hell of a deal. That trigger is north of $100 US here.~Muir

As a follow up. The Timney Trigger for the CZ 550 Magnum does indeed fit in the CZ 527... right until you try to reassemble the gun and find that the trigger itself is too long for the triggerguard depth. I had to grind about 1/8 inch from the tip of the trigger to get the rifle to go back together. Also, you must back off the factory M550 setting of the over travel screw for full function. This leaves the over travel on the 527 just a little shy of 'dead stop' but not horrid. Other than these items, it was a drop in and works great.~Muir

Thanks Muir, I have a CZ 527 MTR in 6.5 Grendel on order, complete with the canoe paddle stock, and that's helpful if the trigger disappoints. If the stock also proves to be a problem then GRS offer a CZ 527 inlet so I can always switch it out.

I didn't mean to disparage your rifle choice. I have been considering ordering one of my own and then 'biting the bullet' and ordering a standard CZ American Varmint stock. These are what I replaced the awfully made polymer stocks that came on my 7,62x39 and 300 AAC. I want to be clear: Only the trigger for the CZ 550 "M" (Magnum) trigger needed any work. The non-magnum model dropped into MY Grendel with no more than 2 minutes work. IT makes the factory SST seem awful.

I am continually puzzled at the MTR stock non-option. It seems bulky and ungainly and more suited to shooting off of a bench. I am considering one of these Boyds "AT ONE" stocks for my Grendel but I;m not sold. At $190 it is the same price as what CZ USA asks for their replacement walnut "Varmint" stocks. ~Muir

No offence taken, I actually agree it looks pretty weird but it is supposed to be designed for shooting off a rear rest or bag. For a Match rifle, which in Europe tends to mean the DJV shooting test events, I'm surprised they didn't include an adjustable butt-plate and an adjustable cheek-piece. The GRS has both and Sako have them on the Black Wolf stock. The Boyd stock looks interesting and they are well priced.

In the UK we only have the Howa and the new CZ in 6.5 Grendel if you want a bolt-action, and I thought the Howa looked a bit bargain basement by comparison with the CZ. In the US you could convert a 7.62x39 CZ 527 or Howa mini-action to 6.5 Grendel fairly cheaply, but in the UK it would at least double the cost.

Here we also have the Ruger American Ranch in Grendel (and 7.62x39) these aren't much to look at but they shoot with the CZs at half the price.~Muir

Hi Muir,

Likewise I'm considering an "At-One" stock for my CZ527 in .223 Rem. My wife quite likes shooting it but it fits me so doesn't really fit her!

I have a guide for adjusting the trigger. I shall send it to you.

Muir, you have an email.
