It might finally be time for a CZ 527...

[Olympus]

I had a 527 in .223 and it was a great gun. I sold it because I have enough .223 guns. I wished they offered the single set trigger in their 550 model.

Are you thinking about the 557 model? The 550s do have the SST. One of my 550s (the 2005 model) has the old-style trigger and the other (the 2012 model) the new style. Actually, I think the "old style" has now been reinstated to the 2015 guns.

 

[Onmilo]

I really need another 527 in .22 Hornet.

I sold my bored to K Hornet a few years back and have begun missing it.

From post #10: "Also, the common, steel-cased x39 ammo uses bi-metal projectiles, which cause considerably more wear than copper jacketed ammo."

What? Is there any truth to that? I've never heard that claim before. I'd genuinely like to know because I shoot almost exclusively Tulammo through my AK

adcoch1: I have had a CZ 527 762X39 for several years now and it shoots, just great, and I shoot it alot. Mine likes the cheap steel cased Wolf 123gr or 124gr HP`s. Shoots it so well that I have yet to start reloading for this little rifle. My Son and I have bought 4 or 5 cases of the this ammo. The CZ 527 762X39 Carbine is just great to carry when you are out just walking around hunting or plinking. I have killed several Coyotes and a couple of Deer and a bunch of other Varmints with it, and the farthest shot was about 225 ydrs. Which is no problem with this rifle and the cheap ammo. IMHO,the Single Set Trigger is just great and it spoils you. My Son and I own five CZ 527 Rifles and we really like them, and each one of them shoots extremely well. Buy a CZ Rifle, and I bet You will like.

I've always wanted a 527, but hate high mounted scopes, has anyone tried the new style extended bolt handle advertised on the Cz USA site? They advise you have a gunsmith install them, but I wonder if that's just CYA.

 

[I6turbo]

Seems to be CYA. I've seen several posts where people have ordered them and installed with no fitting required.

 

[Panzerschwein]

Do the new ones come with the new bolt style?

I've been eyeing the CZ-527 in 7.62 for years now. I just wish they could take AK mags, or at least a 10 round magazine.

It is my understanding that the new ones come with the new bolt handle. Anyone have a newer model? I was able to fit a Redfield with lower rings, but I had to shave a bit off the bottom of the bell for the eye piece.

 

[NuclearMeltdown]

The old style bolt handle has a bunch of unnecessary metal on it that interferes with the ocular scope bell. If you have the old style bolt handle, you could do what I did. I got a cheap 1x30 belt sander at Harbor Freight and shaved down my bolt handle when it wouldn't clear a Redfield 2-7x33. All you need to do to take the bolt handle off is take the bolt out and decock it. Then the handle comes right off. You could also use a vice and files, but that would take forever. The metal was surprisingly hard, and it took at good 45 minutes (at least) of trial and error, taking off a little bit at a time. Reblue as necessary.

The modification cost me $37, and I got a free belt sander out of it

 

[Corn-Picker]

What rings are you all using to get a scope mounted low? The CZ rings are rather high, and the CZ weaver adapter adds a bit of height so even lower rings on top of the rail end up being high. That's one change I'd like to see on the CZ 527; Weaver rails instead of those 16mm dovetails.

I run a New England Custom Gun (NECG) peep sight on mine. I removed the front hood and middle blade sight, and I replaced the front bead with an NECG partridge post. The partridge post was for a 550, so the base required a little modification (sanding) to fit the front sight base on the CZ 527, but now it all fits together and is very tight. This is a really great setup for the carbine in 7.62x39 -- super lightweight, fast on target, and usable for as far as I'd want to shoot a deer with 7.62x39 (about 150 yards). Of course that doesn't help you if your eyes need a scope, if you need one you need one.

Bi-metal jackets don't use chro-moly unobtainium...

From post #10: "Also, the common, steel-cased x39 ammo uses bi-metal projectiles, which cause considerably more wear than copper jacketed ammo."

What? Is there any truth to that? I've never heard that claim before. I'd genuinely like to know because I shoot almost exclusively Tulammo through my AK

^ NO. INCORRECT Myth that needs to die. :banghead: I'm about as tired of seeing this one as I am the one that says steel cased ammo will destroy my 1911 extractor, ejector, blah blah blah.

Hardened tool steel has a rockwell hardness of 650/700 Brinell. Mild steel has a hardness of 120/130. Bi-metal jackets are made from very soft mild steel. Bores/barrels are at least as hard as tool steel and when chrome plated are even harder. Steel jacketed bullets are nothing new. The US had steel jacketed bullets in WWII chambered in 30-06 and 45 ACP. The M1 ball and M2 AP rounds of the era used steel jackets over a lead core with a copper wash over the steel -- just like Wolf bi-metal bullets.

Frankford Arsenal conducted a test with steel jacketed 30-06 rounds around 1946 to determine if the rumors that steel jacketed bullets damaged the barrels more than copper jacketed bullets were true. In their testing they found that steel jacketed bullets not only didn't accelerate wear but they also discovered for the first 1000 rounds steel jacketed rounds were actually more accurate! After 1000 rounds the accuracy leveled off to be comparable to the copper jacketed bullets but no evidence of accelerated wear was discovered through 8,000 rounds of testing on their samples.
Bi-metal bullets do not do any more damage to your firearms than conventional copper jacketed rounds do.

Seriously guys, if the Russkie engineers haven't figured the correct metallurgy in their decades of experience, who will you trust?

I bought mine, a .223 CZ 527 Carbine, in November of 2014. It has the new style bolt handle and the twist rate has been changed from 1:12 to 1:9. I have a CenterPoint 2-7x32mm scope (http://www.crosman.com/optics/scopes/adventure-class-2-7x32-mm) mounted with Warne rings (http://www.midwayusa.com/product/111233/warne-permanent-attachable-ring-mounts-cz-527-16mm-dovetail). There's no problem with the bolt handle interfering with the scope.

This test differs with that assertion.

The steel cases themselves don’t have any effect on the condition of the bore. The difference lies with the projectile – the soft copper jacket of the Federal ammunition simply doesn’t cause the same amount of wear as the bimetal (copper and steel) jacket of the Russian ammunition.

Are you using the medium or high version of that set of rings?

http://www.luckygunner.com/labs/brass-vs-steel-cased-ammo/#erosion

I read the article, which is very well written but focuses on ar barrels and a much higher velocity cartridge with higher pressure averages than 7.62x39. I think we can all agree that harder jackets would wear a barrel faster, but in a 7.62x39 you may not see the results in a decade, or even a lifetime.

 

[bluzman]

I'm using the high, matte finish rings.

 

[Clark]

I paid $930 in 2008 for CZ527 in 19 Badger with Pac Nor barrel.

I blew the face off the bolt twice in load work ups.
The breech has been reworked for more case support, but I have not shot it since.
I am not impressed with the 30 Carbine case head design, nor the CZ527.

I have not bought any more CZ527s.

 

[Iloadntie]

I acquired a CZ 527 American in .223 about ten years ago and I love it...I have been "asset" challenged most of my 39 years of married life and guns just did not fit into the budget. I had more important things to with my assets. I received the CZ as an award and that made a difference in my life, A deeply buried interest in all things guns reawakened. Since then I follow this site, which I truly appreciate, reload, acquire more guns and now get to shoot with my wife when we have time. Six kids and almost 15 grandchildren now in four states with full-time work keeps us busy. Back to the 527, it shoots simply and wonderfully for someone who was definitely an amateur. With just moderate quality optics I can cloverleaf 3 shots off sandbags at a hundred yards. The only drawback I've found is that the 1:12 twist doesn't like very heavy bullets 40 grn. varmint style awesome, over 53 tough to get as consistent.

 

[Missouri Farmer]

I have a CZ452 and it's my favorite 22. I've held the 527 and liked it as well.

 

[minutemen1776]

I've owned two in 7.62x39. I sold the first pursuing something I thought would be better. I regretted selling the CZ almost immediately. Years later, I acquired another. Though I'm an AR guy, I messed with an AK for a while to see if I'd like it. I eventually sold the AK, but I still had a good stock of ammo for it in the closet. That circumstance led to getting the second CZ 527. Though it cost a bit more than the first, the second is the better rifle. The wood is gorgeous, the new bolt design is an improvement, and the trigger is the best I've ever had on any rifle. I also really enjoy the CZ 527's iron sights, so I have left mine unscoped. It's a real pleasure to shoot.

 

[FIVETWOSEVEN]

I plan on getting one soon in X39 soon. I honestly think that it would be better if it could take AK mags. It would be a great complimentary rifle to back up an AK.

 

[adcoch1]

Yeah I wish they took ak mags as well, but I think CZ wanted dependability instead of catering to the ak crowd so they used their own mag design

 

[Katitmail]

I got it to compliment my AK in x39 for deer hunt here in MO. This year I got deer with it and Hornady SST ammo.

Mine was OK from a box, no issues. But it did produce flyers once in a while. Barrel was floating out of the box but would start binding after couple shots. Also, if you take action apart and reassemble - have to hold it certain way so the barrel still floats.

Also, it did have problems with round soft nose ammo - would not feed those.
So. I did full glass bedding job an installed aluminum inserts. Problem with feeding solved. lower and upper parts were about 1mm apart when assembled on factory stock. After I took necessary amount of wood out, did glass bedding - now it's excellent. I get 1MOA accuracy at 1 yards with cheap ammo. Trigger is great.

I'd depend my life on a proper AK mag any day.
