One of my players insists that he can can always use his Lightning Claw for a Parry without readying the weapon first, because there are no minis showing any retracted Claws, but the description in the Deathwatch Armoury clearly mentions the ability to retract them. Otherwise it wouldn't be possible to manipulate anything with it, even with a -20 penalty.
I've offered him he can requisition the Dipole Mag-Lock Upgrade for the Claws to allow an instant Parry, of course this would only be an abstraction and not some real Mag-Lock, but some kind of thought control mechanism to extract the Claws in the blink of an eye.
Any Suggestions?
