The Otis kits are great for cleaning. They do a nice job and they pack up small. It's worth mentioning that you don't have to use their special patches and CLP once you run out. You can use regular patches and your choice of cleaning solutions. Add a stiff nylon bristle brush and a couple lint-free cotton towels (usually sold for cleaning dishes) to your kit and you should have everything you need.

The only thing that Micro Otis kit can't do is remove a bullet stuck in the bore (i.e. a Squib). For that you would need an actual cleaning rod (or properly sized wooden dowel). However, if you use good ammunition, that is a very rare occurrence and, if it does happen, you would be better off taking the rifle to someone more knowledgeable anyway so they can remove it without damaging anything.

Otherwise, have fun shooting and remember to be safe!
