Charges on the left, cases still eject to the right
Larger image here. Interesting, and probably not too difficult to pull off considering you’d only need a bolt carrier with a handle on the left and a new or modified cover. As a commenter at Uncle points out, for the safety to stop the bolt carrier you’d still need the handle on the right side, too. Can’t tell if that’s the case here.
Also, the side scope mounts won’t work with this. The one in the front has optics mounted on the front forearm. Okay for some applications, not so great for others. But then sharpshooters needing top-notch optics with perfect eye relief probably aren’t shooting AKs, are they?
Anyone have more info on these things?
