The Knights Armament SR-15 KS-2 5.56 NATO 14.5" Assembled Upper Receiver delivers a refined AR-15 upper built around a cold hammer forged, chrome-lined 14.5" barrel and mid-length gas system. Paired with the URX 4 free-floating M-LOK handguard and E3.2 bolt carrier group, this upper is engineered for smooth cycling, long-term durability, and consistent accuracy with a wide range of 5.56 NATO loads.

This complete upper receiver is ideal for shooters building a dependable general-purpose carbine for training, home protection, or regular range use. The 12.75" handguard offers generous space for optics, lights, and night vision devices while maintaining a slim, ergonomic profile.
