From D&D Wiki
 Internal Weapon Mount
The recipient has a subcutaneous weapon embedded in her body, usually in a prosthetic forearm or hand. The weapon extends from the prosthesis and is visible when in use.
Benefit: The recipient has a melee or ranged weapon hidden under her skin. Attempts to disarm the recipient of the attached weapon automatically fail. Extending or retracting the weapon is a free action.
Spotting a subcutaneous weapon requires a successful Perception check opposed by the recipient’s Thievery check. The weapon’s size applies a modifier to the Thievery check.
Price: Melee weapon mount: 450 credits, ranged weapon mount 500 credits (the purchase DC does not include the prosthesis or weapon).
Restriction: Military (Blackmarket price: +300 credits)
