    We've choked down gas ports and still had gassy stink guns. Also, my adjustable gas blocked sbr with suppressor... although tuned to wonderful cycle/function, had so much ejection port "snap" that I couldn't shoot it without ear pro. I ended up dismantling the gun. I don't know why that particular set up was so snappy, but the gas block didn't reduce noise for sure.

    This has been my experience with nearly all AGBs. If set properly, it's actually not a bad thing unless you prefer to tune for each load and/or w/wo can.

    When you restrict the gas flow to the action by a gas block instead of a smaller base port, you will end up with more of the tear drop gas port erosion in the barrel over time. The width of the port opening in the bore for the sealing surface of the projectile determines the exposure to erosion. Inside the barrel, it is never better to have a port any bigger than what is required to regulate the gas flow. An AGB is just a band aid for a problem, not a solution.

    What about an adjustable Gas Carrier?

    It doesn't matter how far down stream the restriction is for the barrel port erosion when it is not done at the base port.

    You mean like a Gemtech carrier? I believe there was a review thread on here that had favorable results. Big bucks though.
