Whether you're running a drop-in trigger or sticking with mil-spec, anti-walk and non-rotating trigger pin sets prevent movement, reduce wear, and keep your fire control group rock solid—shot after shot.
We stock premium trigger pins from trusted brands like CMC Triggers, ELF, Strike Industries, and more. Available in both small (.154") and large (.170") pin sizes, these kits are ready for AR-15, AR-10, and other AR-style rifles.
✅ Why Upgrade to Anti-Walk AR Trigger Pins?
Standard trigger pins can rotate or "walk" out of the receiver over time—especially under recoil or with drop-in triggers. Anti-walk kits solve that problem permanently.

-
🔩 Lock your trigger in place – No pin rotation or shifting
-
🧱 Protect your lower receiver – Prevents wear and elongation of pin holes
-
🧰 Easy drop-in install – Comes with locking screws, wrench & retainer plates
-
🎯 Improves trigger reliability – Critical for competition and tactical builds

🔧 Works with drop-in and mil-spec triggers

🔧 Installation Tips for AR Trigger Pins
-
Use a non-marring punch to align trigger and hammer
-
Insert both pins and secure with locking screws or side plates
-
Apply a small amount of blue thread locker for added security
-
Torque evenly – don’t overtighten
-
Test trigger function before final torqueing
Tip: Anti-walk pins are especially helpful with drop-in triggers that don’t rely on spring tension to retain pins.
❓ FAQ – AR Trigger Pins
What are AR Trigger Pins used for?
They hold the trigger and hammer in place inside your AR's lower receiver. Anti-walk pins add a locking mechanism to prevent movement under recoil.
Are anti-walk pins necessary?
If you're using a drop-in trigger or shooting frequently, yes. They increase reliability and reduce long-term wear.
What’s the difference between small and large pin sizes?
Most AR-15s use .154” pins (small). Some older Colt models or AR-10 platforms may use .170” pins (large).
Do I need special tools to install these?
No. All kits include a wrench and hardware. Just a small punch and hex key are enough for install.
