Rise Armament AR-15 Anti-Walk Hammer & Trigger Pins Set

If your AR-15 trigger and hammer pins migrate during firing, a Rise Armament AR-15 anti-walk hammer and trigger pin set is a straightforward fix that keeps your lower receiver's critical components locked in place. Walk-out happens over time with shooting, and this stainless steel pin upgrade addresses it with durable, precision-machined parts backed by Rise's lifetime guarantee. It's made in America and comes with everything you need for installation—no gunsmith visit required.

The set includes matched trigger and hammer pins in stainless steel, each with a .154-inch diameter, plus four mounting screws and two Allen wrenches to simplify installation. Rise engineered these pins to work across AR receiver variants; because receiver dimensions vary by manufacturer, you may need to trim the pins slightly with a file, but longer pins won't harm rifle function or performance. The included screws should be torqued to 8 inch-pounds for best results, with a maximum limit of 11 inch-pounds.

Whether you're running a precision rifle, a competition build, or a workhorse hunting AR, pin walk-out is a common maintenance issue. This set eliminates that problem and is affordable insurance against lost zero or interrupted shooting. Installation takes minutes and requires no special tools beyond what's in the box.

Frequently Asked Questions

Will these pins fit my AR-15 receiver?

Rise anti-walk pins are designed to work with standard AR-15 lower receivers, though receiver dimensions do vary by manufacturer. If the pins prove too long for your specific lower, you can carefully trim a small amount evenly from both ends with a file. Longer pins will not affect your rifle's function or performance.

What tools do I need to install these pins?

The set comes with two Allen wrenches for installation, and you'll need a torque wrench or screwdriver capable of delivering 8 inch-pounds of torque (maximum 11 inch-pounds) to properly secure the screws.

How do I know if my pins are walking out?

Pin walk-out typically occurs gradually over sustained shooting. If you notice your trigger and hammer pins drifting outward or becoming loose, or if you want to prevent it proactively on a new build or rifle, these pins are the solution.

Is this a permanent fix?

Yes. Once installed and properly torqued, Rise anti-walk pins are engineered to keep your trigger and hammer pins stationary. They're backed by a lifetime guarantee.
