Anti-Walk Hammer, Trigger Pins are .154" pins for your AR-15. Perfect for use with aftermarket triggers. It's recommended to use 8 inch-pounds of torque, no more than 11 inch-pounds when installing the screws.
Threadlocker recommended.
Note: Dimensional differences between lower receivers may be present. While not an impediment to function, this set of pins may slightly protrude from the side(s) of the lower receiver. Careful filing of the ends of the pin(s) may be applied to correct this purely aesthetic issue, should it arise.
