The Align Tactical THUMB REST Locking Block pin is a performance upgrade for the Canik Rival / Mete Series and should be performed by an experienced armorer. FIREARM MUST BE UNLOADED BEFORE PROCEEDING! Ensure you have eye protection, a micro flat-head screw driver or similar tool for pushing the slide lock, and a (5/64" or 3/32") steel punch for US, or (2.5mm) such as Glock punch in EU for ease of installation. Be sure to cover the spring-loaded plunger with your finger when removing the pin. Users accept their own liability for damage to their firearm during any part replacement procedures. Contact the manufacturer if you damage a part.
