The hair trigger receiver is a receiver weapon mod in Fallout 4.
Effects[]
When equipped on any applicable weapon, it appears with the "Hair Trigger" prefix. The weapon gains a "more sensitive" trigger in that it will begin firing shots slightly faster upon hitting the 'fire' button as well as a faster rate-of-fire when holding the trigger and a 10% reduced AP cost in V.A.T.S.
