Dewey Chamber Brush

[R.TOKER]

I just ordered a Dewey AR15 chamber brush combo from midwayusa.com. I was wondering if anyone else uses this for cleaning the chamber of their AR. I have had real good luck with the other Dewey products I have used in the past. I had my first failure to eject from my RRA M4 friday at the range. The rifle was extremely hot and I had fired a lot of rounds that day when toward the end of my shooting a case fired but stuck in the chamber. I was able to tap it out with a cleaning rod once I let the rifle cool a little bit. I fired about 60 more rounds without incident. I gave the rifle a good scrubbing when I got home, but found the chamber somehwhat difficult to get to. I did use a .40cal glock cleaning brush to scrub the chamber area that plastic rod was flexible and came in pretty handy.

probably ammo related.

I use the brush that came in my USGI cleaning kit for the chamber and an Otis kit for the barrel.

I have the dewey brushes and use them when I clean my AR. They work fine, though they bend easy. I would say they are on the cheaper end of the scale, but are workable.

As for the round get stuck, I agree with goblue. The casing may have been slightly out of spec or had some gunk on it. If the rifle fired fine before and after that round, it sounds like the rifle is fine.
