I spent some time yesterday cleaning my AR and I had a couple thoughts. For the small parts and the bolt/carrier what do you all use? Do the ultrasonic cleaners really make a difference in cleaning? Also, what is the best way to clean out the gas tube? I've heard some mention using a pipe cleaner, but how so? Do you take the gas tube out of the upper completely or do you just run it in from the receiver end?

I ask because the batch of ammo I used recently was noticeably dirtier than the previous ammo I had been using. I want to make sure I am cleaning the AR as best as I can to keep it functioning well.

First I soak it in some break free and clean a different part. Then I've been using a 20ga brush and mop that came in one of those "clean every shotgun" kits to get the internals of the carrier. Q-tips are my best friend for getting that super hard to reach part where the firing pin rides. I've improvised with cleaning the gas tube - I made my own mini-jag using the internals of 550 and cotton rope soaked in cleaner. Obviously using this method, you need to remove the gas tube entirely.

Chamber Guide.

Cleaning rod.

Bore brush.

From chamber to muzzle. The brush can go back and forth, but the jag and patches need to go from chamber foreword and then be removed. Remove the jag, replace the patch and repeat. When the patch comes out clean, you are good.

The gas return tube needs to be cleaned once every 500 or so rounds. The pipe cleaners go in from the receiver end with very little solvent or carbon cleaner, and you repeat until the pipe cleaner comes back the same color.

For the baked on carbon on the BCG, try the Slip2000 carbon and choke tube cleaner.

Brownells has the long pipe stem cleaners specifically for ARs. I usually shoot some Kroil into the gas tube every few hundred rds, and chase it with the pipe stem cleaner a few hours later. Never had a problem.

I pretty much have the cleaning down, just was wondering if folks had some slick ideas. I clean after each range trip so it's not like I'm letting it build up and then clean it after 500rds or so. Though haven't had the gas tube out yet but based on this last trip I am sure it needs a good cleaning.

As for the the small parts and bolt/ bolt carrier are there significant benefits from coatings like Robar and Fail Zero?
