Man I wish I had this, when I was in a heavy weapons platoon. The SAW gas regulator collar can be a pain to remove at times and this tool looks way more efficient than the Gov issued tool. The SAW and 240B have their own needs that dental tools and improvised scrapers fall short in cleaning. The CSW fits like a glove, maybe some kind of fitted wire or snake brush accessories in the future?

Amazing tool, now it needs a NSN number and I'll be happy. So will my gunners!
