    Until then, the quest for less gas in the face remains.
    I've considered going this route for a while. However I think most of the excess gas comes from the action, blown back out from the barrel as a cartridge is extracted. I highly suspect that a piston system won't do much for gas-face. If you give it a shot please post results!

    See my post earlier. Albeit with a short-stroke Op Rod, it was significantly lessened (but not completely reduced) on a SBR. It was also wicked smooth, but more barrel heavy. There's no free lunch.

    Good to know. Must have missed that. Reading comprehension FTW!

    I have not. Would love to, but it wasn't coinciding with my rail requirements in past builds/rifles. I'm guessing it's similar to the op rod setup in gas, minus the piston.

    I've got a couple of switchblock uppers, we'll see how they fair with suppressors and the gas...

    Did you ever end up trying out the gas vent with your setup?
