KNIGHTS ARMAMENT UPPER RECEIVER KIT FEATURES 

The Knights Armament Upper Receiver Kit, SR-15 CQB MOD 2, features a 5.56mm NATO 11.5" chrome lined barrel manufactured for military grade durability and is free-floated inside a URX4 M-LOK handguard. An improved E3 round-lug bolt design both enhances function and increases bolt life far beyond the industry standard.
