Botach sent me the Bolt Buddy and the Bolt and Carrier Carbon Removal tool for review. Initially, I thought maybe they were one of those nifty things that look cool and work poorly. In the end, I was proven was wrong.

Both tools came in simple packaging and both are made of solid bar stock. They are heavy, appear well machined and evenly coated with a matt finish. The cleaning edges were sharp and even. The biggest difference I found between the two was the Carrier Carbon Removal tool also works on an AR10 bolt head.

I happen to work at an indoor range with a fleet of both semi and fully automatic rifles: truly a great way to challenge them. I took the five dirtiest bolt carrier groups I could find and put the tools to the test.

Taken from a full automatic, this was the ugliest, dirtiest of them all. The above picture was taken after about 30 seconds of cleaning. You can see all the carbon that was removed compared to the rest of the bolt.

Both Tools have a side for cleaning the inside of the bolt carrier, an area that can be difficult to reach and clean evenly. We drop them in our industrial ultrasonic cleaner, an option most people do not have. I was pretty impressed by how well this just cut away the carbon build up.

All the carbon removed from 1 bolt in under 5 minutes. The shiny metal was achieved without any cleaner.


Initially, I wondered if this was a product that I would need, and therefore pay for. BOTACH was able to bring a product that cleans two hard to reach areas very easily. The areas that are arguably the most difficult to clean. This product makes cleaning very easy. Almost completely cleaned without any solvents.  I found no difference in effectiveness between the two products. They were both effective equally. Botach has sold over 10k units. I know why. Because they work.
