Question: can cz 527 shoot 5.56?
Answer: I asked CZ myself and CZ USA said YES it is fine to shot 5.56 NATO and . 223 MATCH ammo in the CZ 527. 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.
