Use the Otis B.O.N.E. Tool to Deep Clean MSR/AR Rifles

Military members and first responders are no strangers to the intricate details of gun maintenance. Modern sporting rifles (MSRs) and AR-15s can have upwards of 100 parts that are integral for the weapon to fire successfully.

One such rifle part is the bolt carrier group, an assembly of individual parts working together to fire the rifle. Cleaning bolt carriers is tedious work, and many gun owners resort to scraping away dry carbon with a knife.

Otis Technology recognized this problem and created a solution. Keep reading to learn why the Otis B.O.N.E. Tool may be your silver bullet for carbon buildup removal.


Carbon Buildup: A Headache for Rifle Owners

The bolt carrier is an indispensable component of semi-automatic firearms like AR-15s and MSRs. The assembly contains the bolt, bolt carrier, and a firing pin–each of which must operate in excellent condition.

When the gun’s hammer strikes the firing pin, the pin is pushed forward and strikes the cartridge’s primer cap. The priming mixture inside the cartridge explodes, propelling the bullet out of the barrel.

The priming mixture is typically a smokeless powder, and while it’s effective at firing bullets, no primer powder burns with perfect efficiency. This means a little bit of carbon is deposited onto the inner walls of the barrel while shooting.

After multiple uses, the carbon buildup gets thicker and can become almost solid, causing the rifle’s parts to stick together, creating an unsafe and virtually inoperable firearm.

How Do You Break Down Carbon Buildup?

Gun operators understand that poorly cleaned firearms are unreliable, but many use irrelevant tools like knives, toothpicks, and tweezers to service their weapons. These tools should not be used for cleaning weapons as they can harm the parts or cause small debris to get stuck inside, making the gun even less safe than before.

Others take bolt carrier assemblies apart and clean the pieces by hand or with a towel. This is also ineffective because layers of carbon coating can be difficult to remove. A damp towel may feel like the right call, but it can compress the layers of carbon fouling or add moisture to the inner parts of the gun, making the problem worse.

Put away these damaging devices and use the tool designed specifically to clean carbon and fouling from the bolt carriers of MSR and AR rifles.

The B.O.N.E. Tool

Otis Technology’s B.O.N.E. Tool is a compact device that can scrape away carbon buildup on the firing pin, bolt, and bolt carrier in minutes.

The B.O.N.E. Tool breaks down carbon buildup in four simple steps:

Step 1: Disassemble the bolt carrier assembly.

Step 2: Insert the bolt carrier scraper end of the tool into the bolt carrier. Twist to remove carbon buildup and other fouling.

Step 3: Insert the bolt into the bolt scraper end of the tool. Twist to remove carbon buildup and other fouling.

Step 4: Insert the firing pin into the firing pin scraper. Twist to remove carbon buildup and other fouling.

It’s as easy as that.

The B.O.N.E. Tool comes in 5.56mm and 7.62mm sizes, suiting most AR- and MSR-style firearms. It also comes with an 8-32 threaded hole so you can twist it with a T-handle grip if desired.
