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 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.

Well looks like I'll go with my original thoughts. Spikes chrome vanadium bcg and an adjustable gas block
