Why would you need a new stock?
Also,,,, the only difference in the 221 and 222 magazine is a spacer. A guy over on Saubier made one a few years ago. He posted pix of it. Simple deal, it's just a piece of plastic. Matter of fact, there's even a few guys that swear they converted 223's to 17FB. They even used unmodified 223 magazines but it's internet hearsay soooo????
Forget the "kit's", here's exactly what CZ needs to come out with.
527 American with a shorter magazine and modified bolt handle to accommodate lower rings chambered in 17FB.
This one has a 9 twist 3 grove Pac-Nor but there's nothing wrong with CZ's 17cal barrels.
He11,,, they already make all those parts in one caliber or another,,, all they need is a reamer.
To bad CZ didn't get on board with the 17FB though. That might have saved it.
Can't say I have seen a 222 in a American configuration. Every cz 527 222 I have seen has been their Lux or the full stock version. Sorry they Do not appeal to me. Which reminds me. Know of anyone who would like a Stock off a CZ 527 Royall?
I believe the 223 conversions may work very well. The 17 Rem Conversion I started out with worked quit well. Though She works feeds great from the 221 Fireball Magazine since changing the trigger guard and magazine over to 221 Fireball.
Back on subject Love the rifle in the photo And I agree if CZ would put something together near exactly like that. Did you say you would like to trade for a Remington 700 LTD LVSF straight up?
The only thing that could hurt sales is ammo. I have been rolling my own from 223 from the start. Not many would go through that trouble. ****ing Remington marketing any way urinating down their own leg. Have a great thing here if they could market Like Hornady, we would have a 17 fireball live and flourishing IMHO.
Any way I agree they already have all the right components. Just need the right reamer, oops! and supply line that we might depend on for ammo or at least brass.
Gave the High Planes Fireball brass a spin and it worked for me with considerably less work. still had to anneal brass and neck turn though.
