Cz-527 Rifle Magazine Conversion
We perform a modification to the magazine and the trigger guard on the CZ-527 that converts the exposed, some feel rather ugly, drop down magazine to a more modern looking flush mounted magazine.



Here’s what we do:
Mill the trigger guard to a flush bottom fit.
We do not offer blueing, so we coat the trigger guard with KG GunKote 1600 Teflon Semi Gloss finish. This is a baked on finish that is Mil Spec and matches the factory finish very well.
Cut the magazine down to a flush fit. Depending on caliber, roughly a ?? of the magazine will extend down below the stock

Modify the magazine release.
WE NO LONGER OFFER THIS SERVICE ON THE CZ IN 22 HORNET…CZ has changed these magazine to include lots of plastic parts that do not lend themselves to this procedure and feeding problems result. We can modify the trigger guard for $55 including shipping back to you. The modified trigger guard still works with a standard 22 Hornet magazine.
The cz-527 in ……7.62, 222, 17Rem, 221FB, 204 Ruger and 223 Rem work great….
All of this is done for $85.00 which includes shipping back to you. Extra magazine can be modified for $30 each. But be aware, a standard length magazine will still fit the conversion. Some folks purchase a second magazine and keep it long for when more fire power is needed. This conversion will result in the magazine holding two rounds.
You need to ship us the trigger guard, the magazine and the magazine finger release.
DO NOT SHIP THE WHOLE RIFLE!!!!
Please Email us for shipping instructions. Do not ship anything without emailing us first. rvb100@comcast.net
This service is only available in the USA. Magazines can not be shipped or received outside of the USA. Sorry!

Here are what some folks are saying about our work:
Hi Roy – I just got my CZ 527 bottom metal & magazine back today – and they never looked so good ! What a terrific job you did!
I love the conversion to the shorter magazine – the rifle looks 200% better, and the parts you worked on would pass as “factory” !
The metal finish is a perfect match to the rest of the gun, and I don’t find a need to file a second finger recess in the stock wood, opposite the clip release – so it looks like I’m good to go.
Thank you, very much, for doing such a nice job – and in such a timely manner, too.
Roy, My CZ conversion arrived today. Excellent job! It adds a touch of class to an already fine little rifle.
“I
just wanted to say thanks. My CZ-527 looks pretty sharp with the magazine
conversion.â€â€¦JDRoy,
Thank you for the quick turn around and beautiful job. Makes the rifle look
much better and easier to
carry.

Got the
parts back for my CZ today. They look great, and seem to function like they
should.Thanks for
a painless transaction and doing exactly what you said you would in a timely
mannor.CRRoy,
Hello Roy received the .17 & .204
parts sat 6-30-07, you did a supper job on all the parts, and after
putting the rifles back togeather I could not be more pleased. they now look
like custom rifles instead of looking junkie with the long clips and gussets on
the trigger guards. thank you for such a great and timely job DWHi Roy,
Just got
the parts back today. Great Job! The fit and finish are excellent
and the operation of the magazine so far is flawfless. It’s a 100%
improvement over the original design. And, to top it off, it can hold
three rounds (I was expecting only two).
Thanks ……Roy,
I posted a few pics on some forums that I frequent so hopefully you’ll get some
more business your way.I can’t tell you how happy I am with the mod. Outstanding job, sir.

Hi Roy,
Thank you for the work you did on my CZ 527. I have several groundhog rifles ranging in caliber however my CZ in 22 Hornet has become my favorite. The flush fit makes for easier carrying and I have not have any feeding problems to report.
Thanks, BrentRoy,
My carbine parts arrived today. If you had a customer survey I’d rate your service very satisfying! Fit, finish and function are all first rate and the rifle can now be carried in one hand at it’s natural balance point. I never did understand CZ’s thinking on a mag that so completely ruined the gun’s ease of carry. Who needs a 5 round mag for
a purely sporting gun. Personally I’ve never had time to take more than 2 shots at anything.
Anyway, a job well done and I will recommend your work to others at every opportunity!Mike
Parts came today, everything looks and fits good…If I do more CZ’s the same conversion will be in store for them.
Glad I found you, thanks!

DaleHi Roy – just returned from a trip and unpacked the trigger guard you did for me. It’s great and looks so much better than the original design.

- CZ 527 mags/metal - LongRangeHunting Online Magazine - [...] CZ 527 mags/metal Hi. Does the CZ bottom metal look like the picture on ...

Is there any way to lengthen the mag or perhaps add an AR15 type bottom on the cz mag for .204 cal? It would be great for my predator shooting.
I imagine you could take two mags and weld them together to create a longer
version. But the big problem would be the spring tension to get it to feed
properly.

Has anyone modified the CZ 527 magazine so as to accept LOA rounds? There seems to be a piece of plastic in there that is not necessary.
What caliber magazine are to talking about. Some of the magazines (222 and 221 Fireball) might have a plastic spacer, and yes, it can be removed to feed longer cartridges. The 223 series magazines (204, 223, 17 Rem) do not have spacers.
It is a 22 hornet that I have.
Yes, the spacer can be removed from the Hornet and it should still feed fine.
Does anyone know if there are any differences between the CZ527 .222 and the .221 fireball
Will the 223 and 204 magazine for the CZ527 interchange?
Yes, they are the same as far as I can tell
Need mailing instructions for cz 527 22 hornet magazine to be shortened. Do you think it will feed properly after this cut-off…let me know. Thanks.
I sent you info….Thanks!
I need shipping instructions
Thank You
