Gas guns don't require the upkeep of a piston gun. Check out the Guns and Ammo torture test done last year. They did everything possible to 4 piston guns and two gas guns. The RRA elite operator and a Larue gas gun where the only ones to continue functioning. Even with their match triggers and match chambers they kept working while the other 4 piston guns were out of commission.
Go ahead and drink the piston Kool-Aid, but time and history proves the gas guns to be better.
I don't drink or Smoke. I spend my money on gunpowder and gasoline.
