I have owned the Magnum Research. The particular model i bought was the carbon fiber wrapped barrel and Hogue Stock. I also own a bolt marlin in stainless varmint with laminate stock. My thinking was to go to the magnum research carbon fiber wrapped barrel to get a lite weight gun. Heres my take on it. I was disappointed it came with a stock ruger trigger group which had the plastic housing. so instantly i opted for a Volquersten Trigger. IIRC that trigger was about $200 something. Then i also didnt like that the Magnum Research had the integrated scope base, it was way to high for a good cheek weld. The Houge stock required some cutting and dremel tool work in the magazine area. There was some rubber in the way that didnt allow the magazine to drop freely when u depressed the mag release. I also had to remove some rubber material from the fore end to allow the barrel to free float. The gun with the carbon barrel was extremely light, actually too light for me. I shook bad with it, no weight to help steady my shots. The action functioned flawlessly. If I was to purchase this gun again i would buy the laminate thumbhole model with the full stainless bull barrel. The carbon barrel shot decent but i did notice that the stainless cap that fit over the carbon wrap didnt line up perfectly with the interior barrel. Nothing huge but for the money i spent i expected it to be better. All said and done i had right at $1000 tied up into it with the trigger, extra mags, rings and scope. I ended up selling the whole package for a loss at $850. If i had to do it over again i would have just saved my money and stuck with my bolt marlin. As far as the CZ u are asking about I have no expirence. The magnum research looked good on paper and it is a great concept, but it just didnt WOW me for the money. Some of these things may be no big deal to u but to me for the money i spent i was expecting better overall performance and fit. Like i said it was fairly accurate but i had a hard time putting consistant groups downrange. Sometimes it would have them all stacked together, other times they would be spread out, may have just been me because i am not used to shooting this light weight of a gun. In the end I chose to sell it. I regret not doing my homework better before the purchase. I hate to say this considering the money, time and stress i spent on it, but I dont miss it. Who knows i could have got a lemon, and it could have just been my lack of ability to shoot it. But regardless its gone on down the rode and i chalked it up to a lesson learned.
