I had always thought the Otis cleaning kits were a gimmick, and nothing that a REAL cleaning kit would take a challenge from.
For work reasons, I just went out and bought a kit. This is a really well thought out design. I'm impressed.
I'll give a rifle a full cleaning in a bit and post a review. I wanted to see if anyone else uses them, and what you thought of it.
This is the kit I picked up: http://www.otisgun.com/pc_product_de...F2596A96C7CB4A
