The Auto-stabilised trait states: "The creature always counts as braced when firing heavy weapons and may fire on semi- or full-automatic as a half action. A creature with this trait suffers no penalties for moving and firing on semi- or full-automatic."

So can you fire a basic or pistol weapon at semi- or full- as a half action or does this only apply to heavy weapons? At first I thought it was only heavy weapons, but there is only one subject. The creature can do X and Y. Also Rogue trader has the exact same wording, and only the suppensor weapon attachment (heavy weapons only) states the full auto is only on the attached weapon.

Any thoughts? It would be sweet to fire two weapons on full-auto using a MUI weapon mount (can fire as free or a half-action).

I would let it happen in my game.

If something can stabilise a 50kg heavy weapon, a measly 8kg basic weapon should not be a problem.

The section highlighted already applies to any weapon. It isn't a stretch to say that movement and semi-full auto fire applies as well.

I think the entry applies to all weapons except for the bracing part that is heavy weapon specific. Just originally I saw the suspensor's weapon attachment from rogue trader and had the impression that auto-stabilization only worked with heavy weapons. I just wanted to make sure that it does apply to all weapons before I try to use it in game (and that I am just not reading it now in the way I want it to work).

Some of the tau weapons are autostabilized, if I remember right, without being heavy.
