Default Direct impingement or gas piston?

So I'm stuck in the cross roads and want peoples ideas and opinions. What is better, a gas piston setup or direct impingement? I do a lot of range shooting and tactical lane shooting, but want something that I can jump out of the water with without it taking my face off. What do you guys think and what are thoughts?

With you gas piston, I know they are cleaner, but other than that what are the upsides to them? I don't mind cleaning my weapon. ( currently infantry in the US ARMY) I read that with the gas piston, you don't have to drain the barrel if coming out of water? Any truth to this?

Buy a DI, I did all the research, was buying a CQB MRP piston,I had decided the piston is what I needed, I ended up with the DI, why you ask? It just felt better, it does everything I have ever asked it to do, and I assure you it's waterproof.

I can tell you training with di includes a yank on the charging handle to break the seal so that the gun doesn't go kaboom.

Nope. Still gotta break the seal and drain the water.

DI has fewer parts to break

That's typical piston BS. Common sense tells you that you'd drain water from a barrel no matter what the cycling action. No doubt the gas tube is an extra issue but it drains too. Let's face it, any weapon that gets submerged needs a little attention and inspection before firing unless you have to get off a shot now.

^^^ what he said...water doesn't know or care what kind of gas system you have and will fill the barrel if the gun is submerged.
