Redesigned hammer pin and anti-rotation links eliminate pin rotation, enhancing system strength, especially for 9mm conversions and suppressed .223 upper receivers.
Notched hammer pin and locking screws secure the trigger, with lube ports for maintenance, while anti-rotation links fit outside the receiver to prevent movement.
Pins are available in Standard .154", Oversized .155", and .170" sizes, with CNC-machining and heat treatment for durability, improving accuracy and trigger control.
