KAC Part #: KM31742



Trigger: Knight Armament 2 stage match trigger. The first stage is a "no-poundage" stage, requiring almost zero force to move the trigger. The second stage requires 4.5lbs of force in order for the trigger to break.

Ambidextrous Controls: The highly sought after Knight Armament lower receiver features an ambidextrous bolt catch, KAC Safety, and magazine release. Perfect for left handed shooters and provides all shooting a more ergonomic experience.

    CA Legal

    If you’re familiar with kac and love in CA, you know the SR15 is banned. Good news is this lower is 100% identical to the SR15 lower, just CA legal and designated SR30. Big thanks to NS for preserving freedom by being willing to work with folks trapped behind enemy lines.
