Magazines and magazine wells can get pretty dirty and they are hard to clean. But there is an easy way….gun magazine and magazine well brushes.
This is a specially designed brush that fits inside your handgun magazine well to clean dirt and carbon fouling. You can also use it to clean the inside of the magazine once you remove the follower and spring. I do this on my AK-47 magazines. I have not cleaned my Glock magazines yet.
After you spray gun cleaner in the mag well use this brush to scrub the well then wrap a clean patch over the brush and wipe the mag well clean. Now you can apply a thin coat of lubricant to make the magazine slide in freely and prevent corrosion.
