Broke my magazine catch spring.....and here is how I fixed it....easy!

[StevefromOhio]

I as many others have had problems when I take apart my CZ 527.  I have the 223 Varmint and it is a great gun out of the box....but it can be better. I did the brass pedestal mod and glass bedded the action. The gun fits tight and shoots even better than before.

The spring that holds the magazine popped off as I was putting the gun back together and I noticed that the spring was bent on the little clip...it was really loose. I took a pair of pliers and bent it back.....bad move....that spring...being spring steel....does not bend well. The little clip broke off. What to do?

  So I ordered the spring clips from CZ......but I wanted to go out shooting today because.....no rain!  First time in 5 days of no rain.
After looking at this problem from another angle, I figured out that that spring has about the same resistance as a little adhesive backed rubber snubber...the kind available at Lowe's or Home Depot. I did have to cut it and did make it thinner.......cleaned the magazine case with acetone and stuck that little snubber under the latch flush even with the magazine/trigger guard case. It is really small as I had to quarter the small snubber and then slice it thinner to work right.....had to be careful.....razor blades are sharp! My fingers know this.

 Put it on....It works better than the factory spring!  And it is much simpler.......that factory spring is a pain in the butt.....The magazine is now tighter in the magazine case and the latch works better than with the factory spring.

Now if you want to do the same, get the small snubbers...mine is black....had to cut them to fit.....but it works.....a lot better than the factory spring......So, I called CZ and cancelled my order for the springs. If you have the same problem as I had, then you might want to try this.....so far after about 250 rounds......it still works great.....still stuck on....make sure you clean off the area that you are sticking it to.....Hope this helps as I know a whole lot of people hate that little spring. Keep it simple!

A little update....the snubbers are a bit stiff....so I went to Lowe's and got a rubber bottle stop that they sell in their hardware area. Sliced a 1/16" thick section and then cut the end in half....it is really small....you cannot see it at all. This is the easiest and least expensive mod you can do....and worth a try.
Got some DAP Rapidfuse glue...three times stronger than super glue and glues everything...watch your fingers! Glues rubber to steel easily.

Folks, this is the answer to the magazine spring issue. It really works well....you cannot see the modification and it works even better than the spring. I really love my CZ 527 223 Varmint. But I hated that magazine spring. About the only thing that I don't like about the CZ527.

Here is a photo of what I did.....very easy to do.....and way simpler and better than the factory spring clip.

As you can see, the little rubber bottle stops available at Lowe's or Home Depot or any hardware store has to be cut. I then glued it down with
DAP Rapidfuse. I found that using regular super glue will also work but I wanted it to stay stuck. Rapidfuse, I have found, works better than regular super glue.

To reinstall the magazine / trigger guard with this mod does not require to have the magazine in the magazine /trigger guard assembly. It just snaps right in.

Hope this helps those who have been dealing with the dreaded CZ magazine spring.

That is very interesting, thanks for sharing! I have had zero troubles with my 527M mag spring myself, but if it goes there is a stop gap solution.

Would it be possible to post or message me specifically what you purchased from Lowes / Home Depot to address this issue? Thanks for the consideration.

My thoughts exactly  Im not sure what a "snubber" is....

Can't say this is right but in the second post StevefromOhio states "the little rubber bottle stops". Could these be the tapered rubber plugs that are used to close opened wine bottles? My guess for "little adhesive backed rubber snubber" would be the round rubber disk that hardware stores sell to keep kitchen cabinets from slamming so much. They come in various sizes and are used where ever you don't want stuff banging together. They just act like a cushion between two hard surfaces that come together. Those are my best W.A.G.S..

This thread is old, but I'm refreshing it because the "fix" worked for me.

I bought a 527M in 7.62x39, that was missing the magazine button spring.  So it wouldn't hold a mag.  I cut a segment of black rubber fuel hose, lengthwise, and glued it on w superglue in the spot illustrated in the photo from StevefromOhio.   The piece of rubber acts as a spring to give tension to the magazine button, and works well. 

My tips: 
- Cut the rubber a little thick (2mm or 1/16") and then dress it down w a file or rasp, a little at a time.  Don't glue it yet. 
- Keep checking the thickness by putting the trigger guard unit, w the button, w the rubber pad, back into the stock and checking operation of the mag release button w a magazine.  When you get the right thickness, then glue the rubber pad in.
- Also, choose the right rubber.  Too soft like foam, and it won't last.  Too hard like plastic, and it won't have a spring effect.

Pros:  Can do repair cheaply, w material already in your shop.  The new rubber "spring" won't become dislodged like the metal spring. 

Cons:  Replacing a steel spring w rubber feels like a step backward (i.e. steel is preferable to plastic).  After 5 - 15 yrs might have to replace the rubber, when it hardens.
