There are a TINY
percentage of the piston AR's that you can rise out of the water without draining the gun and take a shot with minimal risk of a catastrophic failure, but they can all go kaboom in your face. If you are going to play seal wanna-be like that, get some serious ballistic face protection. My piston is really reliable, but that is much further than I want to risk. HK has a few youtube vids that demonstrate their guns doing that, but how many failures did they go through to get that shot? Yeah, I know a seal with a HK 416 got Bin Ladin, yada, yada. And I used
to be one of the biggest champions of the AR piston http://www.firearmstalk.com/forums/f20/ar-15-cycling-operation-discussion-35134/
but I have 2 DI's to my one piston. All of my guns will shoot any brand of ammo. The piston is a little
more reliable and a little
less time to clean. Just not enough to justify the extra cash I had to shell out to buy the setup. I found out through trial and error that the DI system didn't take as much time to clean as my drill sergeants had preached, and a little oil can go a long way. I put together my guns with quality parts, not super expensive, just not bottom of the barrel, and they serve me just fine.
