No I don't. I have one, used it a couple times
I got really beat up on another forum from the anal Annies. OMG how awful you are gonna ruin the barrel!
They claim the debris on the cleaning rod will harm the barrel. Or the rod itself. Well I use a carbon fiber rod or aluminum which is softer than a gun barrel metal, No answer to that either,
The anal way to clean is with a bore guid, only push the patch/brush through do not pull it back, remove the patch or brush then reattach and push it through over and over, Sorry not gonna happen for me.
Plus you are not supposed to clean 22 lr for some stupid reason??
I then asked a logical question on how do you clean pistols or revolvers? No bore guide used there, plus they get cleaned from the muzzle end! No one could seem to answer that,
Don't use bore snakes, they just get dirty and you are running a dirty patch through the bore every time,
