The new PDQ Ambi-bolt release™ for AR15 puts the operator in control of the firing grip at all times. The trigger finger moves from trigger to mag release to bolt release smoothly without moving the weapon from the shoulder. That is why it is called PDQ (pretty damn quick). When seconds count and your life and others are depending on you, count on PDQ. The PDQ Ambi-Bolt Release™ Features: - Military grade steel - Mil Spec 8526 Class 3 type 2 coated - Allows user to lock the bolt back as well as send the bolt forward - Made in the USA MPN#: APRH100012C
