I bought my husband this riffle, and it's not the best of shooters we have. We own a wide variety of CZ's from 2-550 varmints calibured in .308 and 22-250, a 572 varmint caliburated in .204 Ruger 2-452's in .22 LR and then the 452 thumbhole varmint is also .22LR. So we know how these babies will shoot. They are on fire!! We took this little thumbhole out the first time, had it bore sited, so shouldn't have been that bad off, it never hit the paper at 50 yds. Finally at 25 yds we hit paper. Make a long story short we put three different scopes on it and none of them did any good. The best group we could shoot was about three touching the same hole and two fliers out of 5. We used every kind of ammo we could think of from eley tenex to wolf match extra. Which is what we use at all our competition matches. So we box it up send it back to CZ. They kept the riffle for 8 weeks. my husband starts calling weekly after 4 wanting to know what is going on with his gun. On week 7 they tell us yes the gun is defective and they will send us another. We thought "ok" "good" "finally something is getting done". So we asked how long til we get our new gun. They said they were out at the factory but had a shipment coming from the Czech Republic but were held up in customs at the border. Well yesterday the Fed-Ex man came with a gun. The exact same gun we sent off. My husband called today, they said the gun shoots within 'their' expectations and we were stuck with the gun. When my husband questioned about the new one coming, "they never said that"!! Of course. So now we are stuck with a gun that shoots so-so, not the competition gun it was going to be used for. Do you have any idea's on how to make the gun shoot better? We will have it bedded, other than that im not a very happy customer now.
