All Purpose (AP) or Utility brushes are very handy to have when cleaning firearms. They have the ability to get grit, grime and fouling out of those hard to reach areas like muzzle brakes/flash hiders, gas piston heads, bolt faces, action recesses, handgun slides, etc. Utility or AP brushes come in 2 varieties…bronze and nylon. Which is better?
I use both bronze and nylon AP brushes. The nylon are softer and are used to remove light fouling or debris whereas the bronze brushes are better for hard to remove fouling and carbon buildup. Both are safe to use on firearms. I like to use the nylon brushes in the gas tube of my AK-47. It cleans it very nicely. But I use a bronze brush on the gas piston.
Here’s a nice 9 pack from Otis. You get 3 blue (extra stiff) nylon, 3 white (soft) nylon and 3 bronze AP brushes. They are double ended so you can get into very small areas or scrub large surfaces easily. Here’s a link to get a pack of these….Otis 9 Pack of All Purpose Gun Cleaning Brushes from Amazon.com
Otis nylon gun brushes are handy to have around when it comes to gun cleaning. They are awesome for scrubbing bolts, inside receivers, trigger assemblies, gas pistons, Glock slides, magazine wells and magazines. They are effective at loosening dirt, fouling and debris without harming any part of a firearm. They really make gun cleaning easy and faster.
The only drawback to nylon brushes is they will not remove burned on carbon fouling like on the AK-47 gas piston. You have to use bronze brushes to remove this stubborn carbon buildup.
These are Otis Nylon brushes and they work great but you can get just about any name brand and they will work. Otis just happens to come in packs of 25 brushes.
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.
