CZ 527 update

[ChuckDizzle]

Does this happen at the range with real rounds and empties? I'd say dummy rounds are not a 1 to 1 equivalent to the real thing.

I'll be testing this in a couple of hours. You're right, but I've found differences in function testing with snap caps only on extraction for rifles. In my experience the dummies were always an accurate indicator of feed issues.

Fingers crossed that you are right. This is my first box mag fed center fire bolt rifle. I'm amazed at the difference in tension from the first to last rounds, never felt that with internal mags or my CZ 455.

[ChuckDizzle]

I will add though, the rifle itself is a great little shooter. I've been able to get 5 shot groups as low as less than 1.5 MOA which is much better than I expected with Wolf ammo.

Just need to get the mag sorted out.

It's been a while, but I think green groups were with 527 and blue was with Arsenal Sam7. 2 diff ammo. Smaller groups were with non-range friendly rounds. Wolf yellow box groups a little

I have high hopes for the accuracy of this rifle. Unfortunately I only have time to get on paper and function test at 25 yards indoors today.

My CZ 455 is the most accurate rifle I own and produces ragged holes at 100 yards with Remington "premium rim fire magnum" but is a solid .75 MOA with CCI A17 loads. I can only hope the TNT Green performs as well when I'm forced to go non-toxic next year.

First 4 mags through with no problem...feeling good so far.

I have a .223 CZ 527 Carbine. The only problem I've had with the magazines (I have 3 OEM ones) is their cost. Other than that, the rifle is reliable and accurate.



25 yds


50 yds


100 yds (called the flier)

Good news, the rifle performed flawlessly with live rounds. Probably put 15 mags through it at the range, not a single issue.

What a relief.

Thanks Capt Obvious

Your welcome lieutenant.

Did you replace the mag springs? If so, what did you replace them with? If not, then what changed?

[ChuckDizzle]

Allright, I did some digging, took apart the mag, sanded the feed lips a little. Filed the nubs that dictate how far the magazine seats in. Also smoothed out the same hole/notch on the inside and the back of the follower as I noticed the base of the follower sits right about there when theres, you guessed it, three rounds left in the mag.

I suspect the follower was hanging up a little on this hole.

I can't believe CZ charges $50 for these magazines.

So preliminary accuracy testing was done today at 100 yards. The rifle did not disappoint. With xm193 surplus I posted several sub MOA 5 round groups when I did everything right. Even when I was just doing ok groups averaged about 1.25 MOA. Set trigger was a huge help with this.

One of my 3 round groups when zeroing was about a quarter of an inch.

I tried some 45 gr varmint tipped Federal AE .223 and was unimpressed. Not bad, but about 1.5 MOA through the 4, 5 shot groups. I can see why my buddy passed me a box for free.

Can't wait to see next time how my hunting load, Hornady 55gr spire points, perform.

Unfortunately, my phone was dead before I even left the house so no photos, but it would appear bluzman's photos are typical of this rifle's performance.

Fiocchi has always worked well for me if I don't use handloads - 40 grain IIRC. I use them out of a Volquarsten Evolution and they're always well under 1".

I have a few CZ 527s and replaced the set trigger with an aftermarket - Basix I think. The "non-set" trigger can be set very light, the problem with the factory version is that it's in two pieces and while very good imparts a less than crisp pull.

[ChuckDizzle]

Dfletcher, funny you mention that, I have the factory trigger adjusted to almost no travel and just about as crisp as it gets, I thought it was pretty good. However, after shooting maybe 30 rounds with the set trigger it seemed much more creepy. I'll probably use the set trigger often as it became habit to set it after chambering.

I've always had great luck with Fiocci v-max bullets. Great value for sure. I only switched to the spire points because often the v-max bullets were just too explosive and ruined dinner.

Great to hear that you're happy with the results. BTW, I should have noted that my results were with LAX Ammo 55gr remanufactured pointed soft point (PSP) rounds. I used those because around the DFW area, most outdoor ranges don't allow FMJ rounds - urban areas are too close to the ranges so it's a liability issue I guess. Anyhow, congrats and enjoy.

I know it might be late. but I used tikka OEM rings for my scope mount vs CZ rings and it is SO much nicer having a lower scope.

[jmax]

I have a 527 in 7.62X39 with 3 factory mags and have not had a feeding issue in hundreds of rounds. I load cast only and get 5 shot 1.5 MOA groups with my loads.

Of course I came across this after I had purchased a CZ 527. At least off spec springs are an easier fix than poor quality stocks. I'm assuming some of you had heard about the issues some users had with the stocks cracking with less than 100 rounds through them. They all were cracking in the same area, towards the rear of the receiver. Those that were pictured were walnut, although I doubt the beechwood stocks would be immune. I had mine sent off to be glass-bedded.

Naturally I'm not condemning the rifle or the company as a whole. Call it a bad batch, but having sent out blatantly faulty springs with the rifle's only magazine doesn't inspire confidence. Besides the features of the rifle of what had attracted me to get it (sort of platform for a faux scout rifle), I had heard of very positive things about the company and rifle in both quality and customer service prior to getting it. Thanks for the heads up, now I'm off to disassemble my magazines and check the springs.
