I dont have a 550 but do have one cz 527 .223.

Curious how your cz 550 barrel cleans(easy?)and how the bore looks?

I ve been cleaning several of my rifles after a marrathon few days at the range.

My CZ 527 cleans Frickin easy, couple patches of hoppes, let set over night ran a dry patch through and that thing is clean as a wissle and the bore and lands look very nice,(no tool marks/ enclusions or copper fouling) I had not even cleaned that think in a couple years.

Its got to be one of my nices barrels bores. Im thinkin Id like to get a cz 550 .
