Just had a word with the writer, Martin, and he had this to say:
GLs have a Support Weapon receiver, so Quickdraw is based on that. Likewise Recoil.
Accuracy: If the weapon is not specified as Inaccurate as a trait then accuracy is normal.
Take base damage for a GL as the dice damage for a multiple projectile round, since it is a light support weapon type receiver. Recoil is calculated at this value -8, and will almost always be zero.
Useful info, we will start putting a little FAQ together for the Downloads section of the site.
Hope that helps!
