Has anyone used these or know anything about them? Pretty cool concept but I'm skeptical if they work

 

 

Hadn't heard of them before.  They'll obviously leave behind powder fouling from whatever is pushing the cleaning wads out the barrel.  I share your skepticism.

Usually it's not the barrel that needs cleaning for me - it's the gas system (Semi Autos).

This is a solution to a problem I don't have...

Only reason I see using this is for a wet barrel.  That's it.

The only round that will soon be legal in NJ for self defense.

I don’t see how these could work. Maybe if the barrel was dumped in the mud. Normal cleaning I would think the impulse would be too short to really scrub anything out.   

I switched to bore snakes for shotguns, a little cleaner/lube, two passes and it's shinny clean.  Rinse snake with a little solvent (brake clean) ready to go again.  Way easier after each use.

They’ll clean your barrel in a millisecond.  

And your barrel will look like that’s all the time you spent on it, too.  

These things are for the lazy. All firearms need proper cleaning and lubrication for proper function and longevity!

That can be solved by a shot of WD40 and a wipe down.

Cleaning the barrel takes seconds.  I don't see the need even if it does work.

Now, give me a shotgun shell that will clean and lubricate the whole gun and I'll take a case.
