I'm thinking about replacing the stock on my BRNO ZKK 602 chambered for 8x68s with a stock from CZ-USA. Is the 550 Magnum stock the correct stock for the ZKK 602?

Also, some of the 550 stocks include an "F" BLOCK (BEDDING BLOCK). Does the "F" block have any effect on bedding the ZKK 602?

Here's a link to CZ-USA Magnum stocks.

Your BRNO 602 will drop right into a new CZ 550 magnum stock with a good fit. The only thing you will need to do is open up a short section of the front guard screw hole in the wood where it meets the bottom of the action recoil lug. Easy to do with a hand drill. The BRNO uses the same F-block recoil lug system as the CZ 550. If you are going to bed the receiver lug you can discard the F block and do away with that part altogether, especially on a smaller round like the 8x68. If you want to keep the F block, bed up to the rear of the block and use it.

Thanks.
