    Well I built it!

    And in the meantime I've got my issue sorted but I'm little put off by Faxon's answer. They claim I need to pull a firing pin spring when using hard primer milspec ammo and replace it for commercial ammo. They said there's a risk of slam fire using commercial ammo without the spring.

    None of this is in the manual or advised when I bought the upper.

    That's easy enough to do, but the idea of having a gun that could slamfire with the right ammo/missing that little spring worries me.

    Hmm. I?ve never had any spring on any of my AR firing pins. Ever. And I?ve never had a slam fire. Ever. I don?t think there?s enough mass in the firing pin to set off a primer without a hammer strike.

    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.

    My bad. I didn?t realize this was a non-standard platform. Had to look it up. It?s one of those things like if an AK and an AR had a baby.

    Do you have an AR-10 ? They (my Armalites) do.
