Trigger Supply · AR-15 Anti-Walk Pins · Steel · Includes 2 Allen Wrenches

Standard mil-spec trigger and hammer pins walk. Under sustained firing — especially in FRT builds, active reset setups, or any high-cyclic-rate application — those pins migrate sideways and cause malfunctions. The Trigger Supply AR-15 Anti-Walk Pins lock your trigger and hammer pins in place with a set screw on each end, eliminating pin walk entirely.

And unlike most anti-walk pin sets, these come with two Allen wrenches included — one for each end — so you can tighten both set screws simultaneously without hunting for a second tool. The correct installation method, included in the box.

What's Included

Anti-Walk Pin Set

Trigger pin and hammer pin — power coated steel, set screw on each end for dual-side locking.

2 Allen Wrenches

One wrench per pin end. Tighten both set screws simultaneously — the right way to install anti-walk pins. No extra tools needed.

Why Anti-Walk Pins

Eliminates trigger and hammer pin migration — set screws on both ends lock the pin laterally inside the lower, preventing any sideways movement under firing
Required for FRT and active reset builds — higher cyclic rate fire puts significantly more lateral stress on pins than standard semi-auto. Anti-walk pins are not optional on these builds
Power coated steel — durable finish resists corrosion and wear through thousands of rounds
Drop-in replacement — replaces standard mil-spec trigger and hammer pins with no lower modification required
Two Allen wrenches included — tighten both ends simultaneously for even clamping pressure. Most sets make you find your own tools
Compatible with all mil-spec AR-15 lowers — fits any standard lower receiver

The Two-Wrench Difference

Every anti-walk pin has a set screw on the left side and another on the right side. To lock the pin correctly you need to tighten both simultaneously — otherwise you risk uneven pressure that can cause the pin to bind or allow micro-movement on the loose side. Most anti-walk pin sets ship without any tools and leave you to figure that out yourself.

These ship with two Allen wrenches — one for each end. Put one wrench on each side and tighten together. Proper installation, no improvisation required.

Heads Up — FRT & Active Reset Builders

If you are running an FRT, Super Safety, ARC-Fire, or any active reset trigger system in your AR-15, anti-walk pins are not optional — they are a required component. The AS Designs MP5 lowers also require anti-walk pins. Make sure these are in your build before you run it.

Frequently Asked Questions

What are anti-walk pins and why do I need them?

Anti-walk pins replace your standard mil-spec trigger and hammer pins and use a set screw on each end to lock the pin in place inside the lower receiver. Standard pins can migrate sideways — called pin walk — under sustained firing, especially in higher-cyclic-rate builds. Anti-walk pins eliminate that movement entirely, preventing malfunctions and lower damage.

Why do these include 2 Allen wrenches?

Each anti-walk pin has a set screw on both the left and right end. To lock the pin correctly you tighten both set screws simultaneously — one wrench on each side. This ensures even clamping pressure across the full width of the lower. Two wrenches are included so you can do this correctly without sourcing your own tools.

Are these compatible with my AR-15 lower?

Yes. These anti-walk pins are compatible with all mil-spec AR-15 lower receivers. They replace standard trigger and hammer pins with no modification to the lower required.

Are anti-walk pins required for FRT and active reset trigger builds?

Strongly recommended and effectively required. Higher cyclic rate fire puts significantly more lateral stress on trigger and hammer pins than standard semi-auto fire. Anti-walk pins prevent pin migration that can cause malfunctions or damage your lower receiver over time. If you are running an FRT, Super Safety, ARC-Fire, or similar system — use anti-walk pins.

What is the difference between anti-walk and anti-rotation pins?

Anti-rotation pins use a tab or notch to prevent the pin from spinning inside the receiver. Anti-walk pins use set screws to prevent the pin from sliding laterally out of the receiver. Anti-walk pins address the more common failure mode — lateral migration — and are the correct choice for FRT and active reset builds. Note: the AS Designs MP5 lower specifically requires anti-walk pins and is not compatible with anti-rotation pins.
