User marlin61 has a cz550 in 9.3x62 on the EE now. Saw the photos on GP and it looks to be the older version with the thin stock, not the newer chunky 2x4 stock. Hope someone jumps on it.
I have one in 9.3x62 with the thin stock I got from Rob a few years ago (see pic) and I'd never sell it. I didn't realize the new ones had a different stock design which resulted in me selling a cz550 FS in 308 I had just bought new as it felt like holding a 2x4.
I've since picked up 2 more older thin stocked ones, one in 243 and one in 308 for which I have a cz750 10rd mag to convert them into very classy "ranger" rifles.
