It would work, but I would imagine it would be absurdly dirty.

First thing that came to mind is the remington 1100/11-87
In essence, it is a direct impingement system. It doesnt necessarily have a gas tube or a gas key, but it cycles an op-rod (ring) attached to the bolt. I dont think it would be reliable if set up like an AR. ETA, if it was, it would be huge. |

That sounds more like a piston then. |

My Winchester SX3 is Gas driven. It get dirty after you run 400 rounds in a day. The ol shoulder gets a little fatigued also

What's case pressure on a light target load? There may not be enough force to drive anything.

I am just curious why would a DI Shoutgun be dirtier than any other DI operated weapon? In my mind I was thinking of something like the Saiga 12 but based on the AR's DI gas system and of course with the looks, feel plus operation of your standard AR-15. So it would be magazine fed and all that good stuff an off the shelf/modern AR can do.
Edit: Thanks to who ever moved my thread to the proper area. |

Shotgun powders are typically much dirtier than rifle or pistol powders.

I see, I would if keeping such a weapon "wet" would mitigate any reliability issues?

Shotgun shells are very dirty, I know when I shoot a case through my Saiga or 11-87 while it will still cycle the piston area gets very dirty. I don't think DI would work in shotgun or it would have been done already, piston systems are much better at keeping the action clean in this case. |

Due to the expansion ratio of a shotgun, the port pressure will be very low relative to an AR. However, if it was engineered correctly and the gas tube and piston where sized correctly there is no reason why it couldn't be made to work. |

If we use the AR gas system as a model, the size difference between the base diameters of a .223 vs. a 12 gauge gives you an increase in piston area of about 3.75 times going from the .223 to the 12 gauge. I think it could be done at a reasonable size. Would it have any advantages over a Rem. 1100? I doubt it. |
