KNS Precision Non-Rotating Sear Pin for AR-15/M16-Pattern Rifles

The KNS Precision Non-Rotating Pin (KNS Precision part no. NRSEAR) is a precision-fit lower-receiver pin built to replace a factory pin on AR-15 and M16-pattern rifles that can walk, wear, or rotate in place over time. KNS Precision machines the pin with a locking feature that keeps it from spinning inside the receiver, which reduces wear on the pin itself and on the surrounding receiver holes. Builders and armorers commonly upgrade to non-rotating pins as routine preventive maintenance on rifles that see heavy round counts. It is a small, inexpensive part that meaningfully extends the service life of a hard-used lower receiver.
