Otis Technology The B.O.N.E Tool Bolt and Bolt Carrier Cleaning Tool (Select Your Caliber)

its an interesting tool and it does really work so it makes it easier to clean that area. heavy duty good product

This joker works and feels great! Perfect size and durability! It’s easy to use and exactly what you’re looking for!!

Product performs exactly as explained in the description. This is NOT a catch-all for all cleaning of your bolt carrier, but it does what it's intended to do.

Package was marked as delivered on front porch, but it was not delivered on the front porch. Which made me think it was not delivered or delivered to another address but was in fact delivered to the mailbox so I did receive it as promised and product is a exceptional quality, and I am satisfied

Great for my 556 bolt carrier . Cleans carbon good

This deal is way better than I thought it would be

I bought this while trying to assemble a complete cleaning system for my AR15. It works exactly as advertised and as expected. It's really just as simple as it looks, but that makes it durable and I expect it to last as long as the AR, or longer. The fit is perfect for cleaning my gun so it seems their production standards are pretty high. If I were to say anything negative, I'd say it seems like the B.O.N.E could be a little cheaper. However since it's a specialty tool, and since it should last many years, it still seems worth the price. Plus Otis has excellent customer service, which is why I chose this cleaning tool over the other tools made my other companies.

Easy to use. Cleaned out the carbon. Worked for me. Could not clean it this well without it. Rifle returned to perfect operation after a few minutes of cleaning. Stores in grip for field cleaning.

E ok… Ma non ha l’utilità che speravo avesse

saved at least 20 minutes per rifle of scraping and scrubbing and cleaning.. Was amazed at how much burnt on carbon/fouling came off my "CLEANED" bolt carrier, bolt and pin when I tested the BONE tool out.. Fits nicely into either my fore-grip or pistol grip storage holes so always on my rifle... It doesn't SURGICALLY clean your workhorse rifle parts, but gets them into fire able condition with ease and no serious scrubbing needed..

Does a great job, might need to wiggle it around while rotating it to get all of the crud and carbon, but overall, a real work-saver. Love it, wish I had one back in the service.

It came on time and was packaged very well. It is top notch.

Very nice tool!! Fast shipping, must have for AR enthusiasts
