Has a gun been designed that doesn't have an issue with carbon build up?

Question

I've been around guns for a long time and I have a question that has always bothered me.

Presently, semi automatics effectively **** where they eat. I'm talking about the carbon. The more you fire the more it builds up and the more likely jams, etc are to occur.

Why have weapons remained this way for so long. I have seen glocks plow through ammo without jamming but it still uses similar mechanics as other firearms.

Has a weapon been developed that has been able to deal with the issue of carbon ?

Answer 1

Powder residue (in either the action or barrel) is an unavoidable consequence of using gunpowder weapons. No matter how clean the powder may burn, you're always going to have some powder residue left over. If you want to avoid this, you'd have to take dca2003311's advice and go to an air-gun.

As for guns dealing with the powder residue/fouling, there are lots of them. For example lever- and bolt-action rifles are much less susceptible to powder residue than semi-automatics. Blow-back/recoil operated semi-automatics are less susceptible than gas driven semi-automatics. Basically all guns deal with the problem, some just deal with it better than others.

Answer 2

Yes they are called BB gun's, and Pellet gun's.*

Answer 3

Yes, the Ruger Mini models don't allow gas to build carbon deposits upon the bolt. That's why it won't jam the way that an Ar-15 will.

Also, check out CCI/Speer's TMJ rounds that nearly eliminate lead deposits, especially in compensated barrels.

Happy shooting!
