Wilson Combat's Anti-Walk locking pins replace your AR's trigger and hammer pins to ensure that the pins do not rotate or vibrate loose out of the receiver. This is a popular, inexpensive, drop-in enhancement for tactical, hard-use guns and full auto firearms. These pins are compatible with a standard USGI style AR style lower receiver with standard GI trigger pins of .154" diameter regardless of caliber, including 7.62/.308 length AR receivers.
