Otis M-16 Chamber Brush

You really need this to do a good cleaning...

This brush is definitely the same quality I have come to expect from Otis, which is top notch. This brush cleans those very difficult nooks around the chamber very well. I have used this brush for around 200 passes through my AR now and it is still looking like new. I will note that you do need a rod, the Otis pull through system just does not have enough tensile strength to get this all the way into the chamber easily. So if you only have an Otis puck system be sure to build a rod into your cost (a short handgun rod works great). It is a specialty brush and it does cost a lot for what it is, but it works well and it seems like it is going to work for a long time as well. 5 Stars.

This brush was a throwback to my days on active duty. It worked perfectly, and is solidly built. I bought it during my waiting period (california ten day requirement) and when i got my rifle on the 10th day, i found that my rifle came with a cleaning kit included. The cleaning kit was decent, but the cleaning rods that came with it were not very good and didn't fit this brush at all. Luckily, i already had a standalone kit with bore rods, and they fit this brush perfectly. I would recommend this brush as a replacement for your stock brush after it wears down.

This is a nice brush for the price. The expanded bristles in the back really do the job of sweeping buildup out after the stiffer ones up front break everything up. It's a good product from a trusted name and you can't really go wrong here. I use this in combinations with my bore snake from the same company and I'm sure I'll be able to enjoy my rifle for years to come. If you are using steel cased of surplus ammo, this brush is a must have for your cleaning kit. It's well worth the price.

We have used star pads for cleaning the chamber in the past, but wanted to get a bit more aggressive with the build-up. This seemed like just the right additional to our cleaning kit based on reviews. I have the right rod set, cleaners and lube. It is a good tool for the purpose, the bristles do work well to break loose the deep seated grime, but this chamber brush is not perfect. It is incredibly tight, so much so that I worry about marring. Afterwards I noticed several copper bristles left behind in the chamber, laid down tight in the crevices such that a pointy pick was needed to get in there and lift an end allowing tweezers to lift the bristle out. That was an unexpected pain; hopefully that will not be commonplace as the bristles break in a bit and become easier to use. Cleaned well. Had a few issues. Might get better with time. Will come back and revise review if future applications do not show improvement over first use.
