    i just took my stock off to wax the inlet and action areas and noticed something im questioning. When I took off the floor plate/trig guard there was only 1 steel sleeve btween the floor plate and the action. It was on the rear action screw, none for the front action screw. I dont have pics and it's all back together/blu locktited. Do any of you carbine owners have the same situation? Is it Normal for this particular rifle?
    Also, is there a sequence I should have tightened the action?
    I will post pics after testing.

    Never looked at mine, so not sure.

    What caliber did you get?

    Looking forward to your testing results.

    I'd czech mine :p but once you take that stock off it's rather difficult to line up the magwell properly with the action.

    I vaguely remember some sort of sleeve on the back screw so if that is all you found, that's it.

    Thanks chris, I didn't notice any difficulty in lining up the floor plate. It's a nice rifle although I have seen pics of some with stripe like grain that look much better than mine. Just got to see how it shoots now.

    How did it shoot before?

    I think I should have shot it before I removed the stock. I'll always question things if I'm not satisfied with accuracy. It did have epoxy in the recoil lug recess. Heck, I didn't even check if it was free floated yet.

    It's free floated. Take a dollar and check for yourself.;)

    As for lining up the magwell, I always have an issue where the magazine drags badly unless it's perfectly assembled. Sometimes it takes half an hour to get it right.:scrutiny:

    You'll love the rifle. I don't have magazine well issues unless I really torque down on the screws. I backed off a little and haven't had an issue since. Nothing's come loose either. I'll have to work on it a little more to see what I can learn.

    I have the carbine in 7.62x39 (youth version because I prefer short LOPs). Mine is as yours is, a pillar in the rear and none in the front.

    I've thought about pillar bedding and bedding the action, as mine won't do better than 1.5" at 100 yards with premium ammo. I've tried Lapua, Double Tap, Privi, S&B, and a bunch of others; and I can't consistently do better than 1.5" (I get about 2-2.5" groups with cheaper steel cased stuff).

    The accuracy is more than enough for my purposes (deer at less than 150 yards), but I've never pillar bedded/action bedded a rifle so I might try it just for fun. The little 7.62x39 is one of my favorite rifles, it's so much fun to shoot that it always finds its way into the truck when I'm headed to the range.

    own one too

    I too own one in same caliber,and never took action apart [ no reason ].

    It shoot VERY well and out to 100 yards its almost a chip shot .

    And I have shot some pretty cheap ammo out of her too.

    LOVE the light weight and accuracy.

    Here's a little known fact about the 527.

    You can single load it.:eek:

    Polish the outside of the extractor claw and it snaps right over the rim. (It's in the manual.)

    Howdy, fellow Czech lovers. X 39 Carbine, here too. It's a keeper! for sure.

    I purchased two additional CZ metal 5-rd mags from CZ America, and discovered later that one of the mags sat too high in the action; it's feed lips dragged on the bottom of the bolt whereas the other two mags did not.

    I measured the top of the mag to the louver'd stop tabs on the end side of the magazine. The offending mag's stop tab was ground too far. Rather than hassle sending it back, I simply measured with dial calipers the two good mags' feed lips distance then carefully fine-filed the third mag while checking the feed lips gap. When I'd removed just enough I cleaned the mag and did a function check, then blued the bare steel. Bingo. Three good mags.



    The other thing I've learned is that the bore on these might be .310/.311" rather than .308", according to adcoch's post in a different thread:


    So! I went out and mic'd a few samples of the various 7.62 X 39 in my stash... and separated the .308" bulleted cartridges from the .310" stuff. :D

    Some of the brass-cased Yugoslav army surplus has .310 bullets; the older '70s headstamp stuff. I just purchased some newer Yugoslav stuff (both Berdan-primed brass) that has .308" pills.

    All the less-expensive, recent Red Army or Wolf steel-cased stuff is .308" but some of the Fiocchi is .310 as is Winchester white box "Target".

    Have to get out to the range next week (midweek) for a lil' testytest. :cool:

    I don't have the 527 (neary did though) but I do have the Savage scout in 7.62x39. After buying the rifle, I purchased four varieties of ammo to test - Winchester "Hog Special," Hornady steel case SST, Academy sporting good's "Monarch" steel case russian fmj ($5/box!) and the TulAmmo russian-made steel case fmj ammo.

    Since my Savage is reported to have a .308 bore and not the .311 like the CZ 527, I was curious about the bullet diameters vs. the bore in my rifle. I knew the Hornady was advertised at .311, but it measured .310. By my measurements, the Academy "Monarch" was .308, and the TulAmmo and Winchester were both .309"

    They all shot well. The Hornady shot very well (.8"), and the Winchester shot fantastic (.6"!). Even the cheap stuff shot under 2" at 100 yards.

    After seeing these results, I was wondering if the .308 bore is more versatile than the CZ's larger bore. Anyone with the CZ measure their rounds and see similar results?

    I knew that the CZ had a 0.311 bore, but I never even considered that the wolf ammo may be using 0.308 bullets. I assumed they'd be using the right spec since they're an old Eastern block country -- I guess that was a bad assumption. I'm gong to check my ammo with a micrometer tonight.

    I do know that my most accurate ammo (Double Tap) is using the 0.310 Barnes TSX bullet. I've been trying to stick with the European ammo manufacturers, assuming their ammo would be loaded to higher levels and use the right bullets.

    FYI, there's also a significant difference between CIP and SAAMI specs for the 7.62x39; I was reading some threads on an AK focused forum and there was quite a bit of divergence between the two specs.

    This is enough to make me start reloading. How does one obtain load data for a CIP spec 7.62x39 shooting 0.310 bullets? Would an internal ballistics calculator be a good place to start? I fear that the standard reloading manuals may show weak loads, similar to what they do for 7x57 and 6.5x55.

    Sorry guys, no pics yet. I finally got to the range(50yd) and it's zeroed @ 25yds and +2 @ 50. I could have done better but I'm getting 1inch 3-5 shot groups at 25 and abt 2 inch at 50. This is all with irons, wolf mil classic hp. I'm not satisfied with how I shot but I'm satisfied with how the rifle shot. I had a hard time seeing the targets with the irons(8inch shootnc) at both distances so I was surprised with the groups. I must have turned into a girly guy because this rifle really hurts my shoulder. I will try to go again tmrow with a tag along to take pics for me.

    ^ ^ ^ Yes, this sweet little rifle is a bit brisk. As for the iron sights, I'm looking at a Skinner peep sight for mine.




    I hear you. Sounds like you and I are at a similar place in our journey. I do not reload, YET. But I think perhaps you have been studying more! The best to you in your endeavor. I look forward to seeing any posted progress.

    I bought an NECG (New England Custom Gun) peep sight for mine, as well as a partridge front post from NECG (the front post was for a CZ 550 and required a little sanding to fit). It's a really nice combo, much more precise than the stock sights.

    I measured a Wolf JHP dated '96 and it measures .310 at the case mouth.

    I originally bought this rifle with the intention of rebarreling to a 6.5 Grendel. Made the mistake of shooting some 7.62x39 ammo through it first and had so much fun I couldn't make myself do the conversion. I've been saving my brass and now have enough to begin reloading. Remington ammo shot very well; Sellier & Bellot not so well. The web has plenty of load data. Hornady has good .310 hunting bullets and Midway often has them on sale. I'm confident I'll get this rifle shooting <1" groups at 100 yards. Might have already been there with the Remy boxed stuff.

    I put a scope on it because of my poor eyesight.
