    Yes.
    It's the same thing they do on the D.I. AR45 to get enough pressure to cycle the system.
    I figured it would also work on a gas operated AK design.

    This is my D.I. AR45
    The gas port is just in front of the chamber.

    This is my gas operated 9mm AK from Finland. The gas block is home made and little bit bigger, inside diameter is 16mm and stroke length is about 55mm. I have worked with this projekti maybe 7 days. It is still little bit under gassed but, i am going to shorten the gas system about 10mm.

    nice looking set up.

    very cool how you have it open to see ....

    looks like you swiss cheesed the carrier to get your weight down. do you have a settled weight? or are you still working on that?

    tell us why you want to shorten the stroke more? (its a nice looking distance now)

    the initial push from the gas is gone the milisecond it opens coming out of your gas block.. so if you think its under gassed?

    you just need a little more initial push/gas or you need it contained a hair longer. you can get either of those things without changing your stroke, if you want to.

    a touch longer in the gas block housing or hair bigger gas port.

    you got lots of options to play with on this & it looks like you've got an awesome start on it.

    thanks for sharing!

    I am not going to shorten the stroke, i am shortening the gas system (gas block closer to chamber) so i can get more gas.
    There is another video where you can see that carrier is not moving enough backwards.

    Like the left side charging system. Will you be able to modify Uzi mags to fit also? Lost the bolt open feature on my AR15 9mm but the price of magazines was worth the effort of cutting the notch to match. Very nice!
