Quality Experience
I found placing an order with Otis to easy and promptly processed. The quality of the tool ordered was high quality and met all expectations.
Good tool, but not worth replacing other high quality BCG cleaning tools
Otis' BONE tool was effective -- but no more effective than much cheaper flat, more compact, and lighter bolt carrier group cleaning tools I've used in the past. Like a relatively few of the other higher quality brands, I'd recommend this Otis tool specifically because I do trust the brand to deliver a quality tool with the correct tolerances that won't damage my weapon. Would I buy this again, though? No -- it's taking up two to three times the weight and volume of other quality BCG cleaning tool I've used and does cost a bit more while delivering about the same results.
B.O.N.E. Tool / Great tool !
I ran 150 rounds through my DDM4 prior to cleaning. I wanted to see if their was anything this tool would find after what I consider a thorough cleaning using both metal/nylon brushes, CLP and lots of patches. Once I was satisfied with my cleaning I then started with the BONE tool in the bolt carrier, and just prior to bottoming out, I "felt" the resistance from leftover carbon stuck inside. I gave it a few twists and it easily bottomed out while twisting. I found some small bits of carbon in the blades. I then cleaned the bolt and firing pin. I definitely got some stubborn carbon removed from the bolt and a small amount from the firing pin as well. Overall, I think it's a great tool and definitely does a thorough carbon removal of the small stubborn leftovers !! I will now definitely start with this tool prior to the normal cleaning process.
