this AA is nice and it looks badass! But.. for some reason when the second bullet is fired, it causes the whole gun to glitch, maybe its just my algodoo. Sometimes this gun double feeds or fails to eject the spent casing in time causing it to jam. I am not a gun expert but I suggest to add a latch mechanism at the bolt so that when the gun fires, the bolt could latch the spent casing and eject it.
