CZ-527 build as a 300-221

Hmmmm.....

I understand the idea, I'm not sure if I like the mag being open like that though. It looks to me like the cut wouldn't completely be covered by the magwell.

I'll have to think about this for a bit.

Did not like the looks of mine at first, but so far no problems. You are correct it is not covered by the magwell---has about 1/2 to 5/8" open. With 4 rds in the mag and you can, (if looking hard), see the bottom of the follower.

It works very well on mine, and I am not complaining about it, quite the opposite

There not much choice if you are using the 223 action.

If you intend to use the 7.62x39 action, then keep it in that calibre but with a .308 barrel instead of .311 and with a 1 in 8" twist, then you can use the 7.62x39 mags.

Cz is producing this rifle in 221 fireball, 222, 223, 2o4 and 7,62x39: each action has its well machined at different length and magasines are all differents in lenght and /or width.

d-mon, You sure about that? I just talked to a guy that says he has both a 223 and 7.62 and says the magwells are identical, and while the 7.62x39 mag does fit in the rifle perfectly, it does not hold a 223 case, whisper or not.


As far as the mag cuts are concerned I'd be much more comfortable if the cuts were not open to the world. I'll patch them up if needed.

Here's one I had done a few years ago. PacNor did the rebarrel job for me. Only drawback to the CZ527 is when it comes to scope mounting. Gotta use very high rings for the scope to clear the bolt knob. Other than that, great little rifles.

Second picture is of the modification that must be done to the mag to allow those fat .30 cal bullets to fit in a .22 cal space (the bullets pictured are 220 gr Sierra Pro-Hunters). I had my local machinist modify the mags. Very simple to do. He just chucked it up in the end-mill and milled out the dimple. I had him only machine down so far so that the relief-cut doesn't show below the line of the weapon when the mag is in place. That dropped the mag capacity to four instead of five.

I cut the entire scallop out on my mag and shortened the followers feet about .1". Now it holds six.
