Tri Shot Shotguns
 

I heard something happens to the tri shot system that the Marui shotguns work with. They somehow stop working after lots of use? Can anyone shed some light on this for me?

Most likely you're thinking of the tri-nozzle breaking.

Impossible to fix?

You buy a new tri-nozzle.
Might be slightly hard to find though.

That's it? The doesn't seem any more of a big deal than a slide cracking, or a motor seizing. I thought they would just completely become useless forever after.

Nope. Just a rarer part.

Seems like something I could obtain easily from the Hong Kong spare parts places relatively anyway. Alright, time to acquire me one of these things, then.
