has anyone used this on their M4? I read several online reviews and it looks like a worthy product. I've been having a hell of a time cleaning the inside barrel of my M4. I can't get the plastic skid marks off. https://huntegoltd.com

I picked up my Benelli m4 tactical last week and ran into the same issue as you I thought I was going to break my ******* finger trying to get that back in the weapon. I read this thread you guys saved my ass I appreciate it
