AR-15/AR-10 – Anti-Walk Trigger Pins – Small Pin
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
The CMC Triggers Anti-Walk Pin Set is a small-pin trigger and hammer pin set for compatible mil-spec AR-15 and AR-10 lower receivers. It helps retain the hammer and trigger pins so they do not walk out under use.
Fitment
- Fits compatible mil-spec AR-15 and AR-10 lower receivers.
- Small-pin size: .154" diameter.
- Works for compatible trigger and hammer pin replacement / retention setups.
Does NOT fit
- Does not fit large-pin receivers.
- Verify compatibility before using with non-standard or proprietary trigger systems.
What it does
The anti-walk pin set uses cap screws to limit pin movement and help prevent trigger and hammer pins from drifting out during use.
Why it’s worth it
This is cheap insurance for a trigger install, especially on rifles that see real use. If your pins start walking, your rifle is trying to tell you something, and it is not whispering poetry.
