Prime receiver

The prime receiver is a weapon mod for several weapons in Fallout 76.

Effects
The prime receiver greatly increases weapon damage and deals bonus damage to scorchbeasts and Scorched. It comes at the cost of requiring expensive ultracite ammo variants instead of standard ballistic munitions.
 * +25% (+60%  against Scorched)
 * +100% value

Crafting
Weapon modifications will modify an existing weapon, and any modifications previously equipped on the weapon will be destroyed, not unequipped. Loose mods cannot be crafted. Plans can be found on both the scorchbeast queen and regular scorchbeasts, with a chance of 2.63% and 0.13% respectively.

Location
Plans for the prime receivers for various weapons can only be attained from the corpse of the scorchbeast queen upon killing her and looting her body at the end of Scorched Earth, but only if the player character took part in delivering the killing blow to the queen or delivered a large portion of the damage to her before she dies.
