CZ-527 build as a 300-221

Frank,

Thanks. I kinda got into the 223 rifle on a whim so I'm glad to hear it's a good host.

Can you explain a little bit about the mag modification?

Thanks

This is an AR mag with the same mod

They do the same thing to the CZ. It's not necessary in the AR IHO, but I hear the CZ needs it. The CZ is BAD ASS by the way.

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.

Alleycat, sent to a PM.

PM sent back at ya.

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.
