If you need parts you might try Cajun gun works. I haven't used them or Angus at CZ but I hear/read good things about both. I shoot the PCR and it just keeps getting better, more accurate than I am and it eats anything I have put in it. That includes win whit box, rem bulk and the cheap russian stuff from walmart. I would like to shorten the reach to the trigger and cgw has that kit just getting the funds to do it. Have ordered a holster kit from Old Faithful should be here in 3-4 days. Will take some picts and post how it fits after.
Good shooting
