Locking pins are a popular, budget-friendly upgrade for hard use and full auto firearms which replaces the AR trigger or hammer pins. Not only do they provide an extra layer of security to prevent loose rotation or vibration from occurring in your receiver, but also can be installed into any standard USGI style AR lower receivers with .154″ diameter GI trigger pin sizes – even 7.62/.308 length. Get this pin set and keep your trigger unit locked in place for good!
