Can anyone explain the XCR's operating system?
How does it compare to the SIG 556? or Colt gas piston upper?
I am familiar with the AR-15 system and acquainted with a gas piston system.
Please educate me.

Is there any info in their brochure?


I've never read it, so I cannot tell you if there's info on the gas system or not.
