AR-15/M16 Anti-Walk Receiver Pin Set, .154 Diameter, Steel, Nitride Finish, Black

AR-15 and M16 Anti-Walk Receiver Pin Set, .154 Diameter, Steel, Nitride Finish, Black

This is a steel anti-walk trigger and hammer pin set in a black nitride finish with a .154-inch Mil-Spec diameter, compatible with standard AR-15 and M16 lower receivers. The set includes two anti-walk receiver pins, two hammer and trigger posts, two hex keys, and an installation guide tip. The anti-walk pin design addresses trigger and hammer pin migration during operation and helps reduce wear and potential enlargement of the trigger and hammer pin holes in the lower receiver.

Anti-Walk Pin Set

The anti-walk receiver pin set is machined from steel with a black nitride finish at the .154-inch Mil-Spec diameter, the standard pin diameter for AR-15 and M16 lower receivers running standard fire control groups. The two anti-walk receiver pins replace standard trigger and hammer pins in the lower receiver and use the included two hammer and trigger posts to lock the pins in place from the side of the lower receiver, preventing the lateral migration that can occur with standard smooth pins during sustained use. Addressing pin migration at the receiver level also helps reduce the long-term wear on the trigger and hammer pin holes in the lower receiver body that repeated pin contact and movement can cause over time. Two hex keys and an installation guide tip are included in the set to support the installation process.
