## Questions & Answers

A: This is an original item but you still need other tools aside from this to clean your bolt action carbon free.

**Q: Can i use this tool on a 6.8 spc bolt??**
A: Pretty good tool to have around just in case you need to clean your bolt of bad carbon build up.

**Q: Will this tool work on a AR10 308 as well?**
A: I haven't tried it on a 308, but it works well on the 7.62 x 39 BCG.

**Q: Can you put a patch to clean the bolt carier?**
A: Yes but you don't need to. Carbon foulings chipped off clean.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great tool that can make cleaning your AR-15 a little easier.
*by D***Y on January 25, 2016*

I just purchased my first AR-15 recently and I figured that I would just use my regular rifle/shotgun cleaning kits for this gun as well. While I could use some pieces of these cleaning kits, I soon discovered that some tools specifically designed for the AR-15 would make the job of cleaning specific components a lot easier. The carbon build up in the bolt carrier group can get pretty bad, especially when you've got a box of cheaper rounds in the mix. Watching a few videos on YouTube concerning the disassembly and cleaning of the AR-15, I noticed that some were using something known as a CAT AR-15 tool that really helped in cleaning the carbon from the interior walls of the bolt carrier and the bolt tail radius. The price of this particular tool was a bit much so I looked for some alternates that would essentially do the same thing. A few videos and reviews later, I was brought to the attention of the Botach CRT tool. The price was a bit more reasonable and many spoke highly of it, so I decided to go with it.It's a small tool with an adjustable fork that according to some of the video demonstrations that I saw, can be adjusted to work with a 308 as well. I am using this tool for the .223/5.56 AR-15. The design has changed a little bit from some of the older video post that I saw. There use to be some serrated areas on top of the two forks to work as finger grips for spinning the tool. They have been removed but I didn't find turning the tool difficult without them. Also, the older model had an open area for cleaning the firing pin in the "handle" of the tool. You can now see three individual holes in this area and they perform the same way. My firing pin fits in each one and this also does the same thing to clean carbon from the flat base of the pin. The tool came shipped in a small plastic bag and I just keep it in that when storing it in my gun cleaning box.I'm new to the AR-15 world, but I know it's important to keep your guns clean and to take them apart for a better understanding of how they work. After cleaning my gun for the first time, I realized that my standard rifle cleaning supplies were not exactly designed to clean some of the components that make up the AR-15. This tool can certainly help with some of those areas. I had cleaned my gun the best that I could without the tool but when this arrived, I broke the gun down again and used it to see how it would perform. I was able to scrape away quite a bit of carbon that I wasn't able to get at or remove during my previous cleaning. So it does work! I also recommend checking out some videos on the web where you can see this in action. It's a handy little tool to have and it can make cleaning your AR-15 a bit easier. I recommend.

### ⭐⭐⭐⭐⭐ If you own an AR-15, you need this tool
*by O***9 on February 19, 2017*

Wonderful tool. An AR-15 can really gum up all the parts in the bolt carrier group, with lots of carbon deposits blown back and baked on from the burnt propellant used to operate the direct impingement system.This small tool allows you to scrape almost all the burnt deposits off of three of the areas that get it the worst: back end of the bolt, inside the bolt carrier, and the firing pin. Squirt a little Break Free (or other) CLP product on the parts, let them sit for five minutes, use the K-Z CRT to scrape off most of the carbon, and use a brass brush and cloth/patches to take the cleaning task to whatever limits you want (...I'm lazy, can't see taking it to the white-glove-test level).There are similar tools out there to clean the bolt and bolt carrier, but most are more expensive. I haven't used all those other tools, so my advice should be taken with a large grain of salt -- but from what I've heard and read, none of them appear to work better than (or even as well as) this one does.

### ⭐⭐⭐⭐ Really nice and high quality.
*by B***S on February 23, 2016*

Works really well to remove carbon from your BCG. It's debatable on how useful it is to clean carbon from your BCG, but if you do this tool makes it easy. My only complaint is the firing pin cleaning holes. They clean the shaft properly but the flat side that faces your BCG isn't cleaned at all. The other BCG tool has slits cut into the face to help cut away carbon from that area of the firing pin. The adjustable section is extremely useful if you have ar-10s as well as ar-15s
