Info on the CZ 527 Varmint .223 REM

[sirgilligan]

The CZ rifles chambered for .223 are also good for 5.56 NATO.

Directly from CZ USA:

I'm sure you know this already, but our rifles are built to CIP spec, which doesn't differentiate between .223 and 5.56, it uses the higher pressure of the two and considers them one cartridge. So our rifles are built to shoot anything from match .223 to surplus 5.56.

For those of us that have 5.56 semi-auto's and would like a bolt action rifle then the CZ is an excellent option in my opinion.
