I bought a CZ Alpha 600 and it would not group well at all. After checking all the normal things I sent it back to CZ. They were great to deal with as far as sending me a prepaid label etc. They responded quickly that the gun was defective and they would replace either the barrel or provide a new rifle…whichever they got first. Estimated time was 4 weeks and they were to send weekly updates. It has now been almost 12 weeks, no response from them, no answer to multiple emails, and no updates when I’ve gotten them on the phone. I’ve requested a refund but doubt that will happen. I’ve heard good things about them and I really liked this rifle…except that it wasn’t accurate…lol. It was on a special a while back from some company on the Monday specials so I gave it a try. Have others had this problem with CZ?
