More on the Ruger SR-556

The Ruger rep in the booth seemed to be pretty interested in telling me about their patented gas system.  Here are some pictures showing here:

Gas Piston from Ruger SR-556

They described this as a two stage gas piston, meaning the first little nub there gets the gas piston starting to move back, but with less impulse than a normal gas piston AR.  They claim this reduces felt recoil, since the gas rod accelerates more slowly rearward.

Gas Regulator for Ruger SR-556

The Ruger rep was anxious to show me their gas regulator.  It ships on setting two, which is good enough for most commercial ammunition.  He said you could turn up the gas for lighter loads, or turn it down for higher loads.  You could also turn it completely off for suppressor use.

    I really like the idea of turning off the gas system for suppressed use. It’s a feature I’ve wanted for a long time.

    That being said, I don’t yet have a job (just graduated law school) so I can’t buy one.

    And I can’t find ammo. And I’m not interested in 5.56. If only this was available in 6.8 SPC it would be perfect.
