Hinged Floorplate for CZ527

[Bogmoor]

I have an old, but excellent condition CZ527 in .222 with the usual steel box magazine.

I only have one mag for the rifle and after a long search for a spare, I did buy another off a chap on here, but Royal Mail lost it in transit.

I'm concerned that the mag I have will eventually fail, so was thinking about modifying the rifle, as it's a keeper.

I know there isn't a conversion kit to modify CZ527 to Hinged Floorplate, but would a gunsmith be able to fabricate a modification to Hinged Floorplate?

Not really.

I bet @Edinburgh Rifles has a spare mag.

These rifles are in the buckets in the upcoming holts sealed bud as well

Not impossible but, I think the CZ 527 is a single stack magazine and the feed rails are part of the magazine. Can you load it from the top? Most top loadable magazines are double stack with the cartridge held against one rail by the force of the cartridge below. When you load you push cartridges in sideways.

With a single stack you have to start with cartridge ahead of the magazine and then slide it backwards under the feed rails. Whether you can do this with a single stack fixed in the rifle I don’t know.

Edit: it got me thinking. Only single stack rifle I have is my little Brno 22. Just pulled it out. Magazine in place. Take a cartridge, put nose of bullet into chamber, press down back of cartridge and slide it backwards under feed lips. Next cartridge do the same etc.

A 527 has a bigger action port and 222 less fiddly than 22 rimfire. So I would give it a try loading anf unloading through the top. When unloading from a fixed mag you don’t need to fully chamber each round, just push it forward enough to release from the feed lips. Either use the bolt, or a finger (but watch out for sharp feed rails).

If that works then I suppose you could permanently fixed the magazine inside the feed well. Indeed you could shorten it so that it is flush with the bottom metal. Take a file to the front of the trigger guard to make much more akin to a normal rifle guard. You would then need a floor plate to hold in place the magazine follower spring. which could be cut from a piece of steel plate. This could be hinged and catched or screwed to the bottom metal.

That would however be quite a bit of work, that if a gunsmith is charging usual labour rates would be prohibitively expensive.

The question has been asked before on other forums

Bottom Metal for the CZ 527

Anyone know of anyone making a hinged floorplate and internal magazine for the CZ 527? This cute little action is straddled with one of the most hideous magazine systens ever. I have the Calhoon single shot adapter and CZ 3 shot magazines. They help considerable, but leave lots of room for...

Rifle mags had 3 and 5 round mags for the 527 - I bought one just a few weeks back

Hi Jock,

Thanks, but .223 mags don't fit the .222.

Cheers

I have the 527 in .223 as a Stutzen. It's a beautiful wee rifle, but oh how I hate the five shot mag'. It ruins the lines of the rifle. There was a three shot conversion kit that tidied up the trigger guard, had the mag' sit flush, and shortened the release lever, but it's been discontinued sadly. It's the only thing I would change about the rifle

Thanks Heym, but it doesn't work. Not enough room.

Looks like I'm stuck with the rifle (which I love) as it is.

I've seen folk cut the mag well web to tidy the trigger guard and then cut a mag down to fit almost flush.

I've seen that, too. Don't have the courage to try it though

Nope. I only have one magazine and don't want to bugger that up!

Drop Holts, Edinburgh Rifles or any of them an email you will usually find they have a bucket of magazines somewhere of which a few will always be CZ527 in 222 and can usually be persuaded to part with a couple for a few quid. As to single shot and floor plates, 3d printing, although i think it was calhoun in the states who made one.
The challenge having tried this with a CZ527 in 20 practical sometimes the extractor claw can fail to go over the lip of the cartridge particularly if they are a bit older and not quite as robust as they once were. You can end up with a case struck in the chamber not badly you just need a rod from the other end to knock it out, one frustrating day at short siberia doing this when trying to zero the rifle.
This is incidentally how i also found out that the various calibre actions are slightly different lengths when i tried to install .223 bottom metal on the 222 rifle subsequently.
Failing that, CZ usually ship from the Czech republic, not the cheapest mags on the planet but they last well. I now have a CZ527 in 221 fireball, lovely little rifle in a very underrated cartridge.

Hi there, I just read your reply. No idea why I didn't get a prompt to say there was a "new" message.
Thanks for the info. Message heading to Holt's.

No problem at all, glad it was of some use. Good luck with the hunt.
