Hey, thanks for the latest pics & links, guys!

I'm confused about what's the difference between gas piston, gas operated rifles. Most of the S&W M&P's say Chromed Components: Barrel Bore, Gas Key Bolt Carrier, Chamber. So, can you explain what's the difference in a piston gun & a Gas Key Bolt Carrier? I am cornfused!
