I have a full and complete understanding of the DI operating system for the AR type rifle.
So I get that the gas goes to the gas block and down the gas tube and PUSHES the bolt carrier down the reciever extention tube and the spring throws it back to the front that picks up and chambers a new round and you're ready to fire.
How does the piston system work? With the Rock River PDS there is obviously not a spring in the stock required to fire.
Basically, I don't get it.
Help?
