sur google ya un gars qui donne sa comme explication
From my understanding you are supposed to trash those when they start giving you problems and buy new ones. Or try to return them to the manufacturer for a replacement. That's why the Ruger BX-25 mags are so popular amongst 10/22 shooters.
A quick google search revealed a few things that could help:
1, Dump them in hot soap and water. Let it soak. Blow dry them and spray them down with oil to keep that spring from rusting. That spring rusts so easy though, it's no guarantee that this method won't just make matters worse.
2. Do NOT use a solvent like Hoppes No. 9. This will apparently melt the magazine.
3. A can of compressed air like you would use to clean out your keyboard or small electrical parts will do some minor cleaning if you have small particles keeping parts from moving.
And lastly, here is my suggestion as to what I would do.
1. I would try to clean it with a can of compressed air.
2. If that doesn't work, since you already have factory mags to use, I would try to disassemble, clean, oil, and reassemble that mag. I would use a small saw to cut apart that mag then clean it out. I would use hot soap and water on the plastic parts. And a solvent like Hoppes No. 9 followed by a lubricant like Rem Oil on the metal parts.
3; Then try to reassemble it with screws and some type of bracket that I got from a hardware store like Lowes or Home Depot. Or even glue it back together with some powerful glue like Goop and press it together overnight so the glue would dry and cure.
4. If I screw up and have to trash the mag, oh well. I have other mags and that's really the destiny of 95% of Butler Creek 25 rd mags anyway.
