Thats a nice kit but doesnt have near the components of these kits, plus I can use the bore brushes that I already have to make up for the other calibers but I personally dont own a lot of different calibers and I use my one piece on my shotguns.
I will get one more boresnake, I use them more than anything else. I carry them in my range bag. My Otis kit has almost everything in these new kits except for a couple of the cleaning pics and the longer brass brush handle.
