What is the difference between large and small pins? I have a standard AR-!5 lower.

Answered by Todd, Gear Expert, from IL, United States, on September 21, 2021

The VAST majority AR-15 receivers are “small pin” receivers (this is mil-spec), but some older Colt AR’s are “large pin” receivers. This refers to the size of the FRONT takedown pin hole. If you have any question, just measure the front takedown pin hole. If it’s.25″, then you have a small pin receiver..315″ is the large pin.
