AR-15 Pivot Pin Detent
The United Defense AR-15 Pivot Pin Detent is a mil-spec replacement detent for the front takedown (pivot) pin on any standard AR-15 or AR-10 lower receiver. Machined from hardened steel to factory tolerances, it works with the detent spring to retain the pivot pin and prevent it from walking out under recoil or handling. Whether you're finishing a fresh lower build or replacing a detent that pinged across the bench during disassembly, this small part is critical to proper function. A smart spare to keep in any AR builder's parts kit.
