External Weapon Mount (PL 6)
The recipient's prosthetic arm ends in a weapon
instead of a hand.
The recipient has a melee or ranged weapon
attached to a prosthetic arm. Attempts to disarm the recipient of the attached weapon automatically fail, though the weapon can still be attacked (like any other weapon) in an attempt to destroy it.
10/5 (mount only).
Base Purchase DC:
mount 15, ranged weapon
mount 17 (the purchase DC does not include the prosthetic arm or weapon).
