I would like make mounted weapon. I have AKM in attachment slot and prepared getter for Weapon_Base.

Then I am trying shoot using

WeaponEventBase weapon_event = new WeaponEventTrigger;
        	wpn.ProcessWeaponEvent(weapon_event);

but I am getting this error

[wpnfsm] AKM:11502 chamberFromAttachedMagazine, error - cannot load chamber!

those AKM have magazine attached and see bullet in chamber

when take in hands from that slot, I can shoot instantly

Is there possibility to remotely control weapon and shoot when is not in player hands ?
