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

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.
