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.

Scoop: Good info, missing pics

este - Don't know what's wrong. The pics show up just fine for me on two different computers.

wtf?

They don't work on my work machine... That's pretty damn strange. I'll check when I get home.

That's the kevlar varmant stock right? I have a few questions about that if you don't mind. I'll PM you and add along my email address.

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

Leahcim: any chance of pictures?

Agreed! I'd love to hear more about that. If it was only .1" I wonder why they didn't just design it that way?

I'll cut the entire dimple if I could fit 6, in a heart beat.

Mine was built on a .223 by Patriot Arms. (now American Precision Arms)
They did not cut out the indentations in the magazine. At the time, they said they typically build Whispers on a 7.62X39 gun as the mag does not require modification. They charged $35 extra to mod the .223 mag to accept Whisper cartridges. I have since bought an extra mag to modify like they did.
