I want to challenge with this and try to get more info.

But in looking at the bolt carrier (which is totally different on the ARAK-21), there is a lot more firing pin travel in the carrier. I'm not sure if that means it's possible or not. Firing pin looks like a standard AR pin/weight.

Maybe it's on me to take some various commercial ammo out next time and see if I can make it happen? Without posting results?

But I can't get that gun to run with the spring in using M855 or M193.
