Brownells is proud to offer this line of Knight’s Armament SR-15 MOD 2 complete upper receivers that allow you to easily complete a build or upgrade a rifle with battle proven quality. Built around a chrome lined, cold hammer forged barrel in your choice of 11.5”, 14.5” 16” & 18” lengths with a Mod 2 gas block, and fitted with a KAC 3 prong QDC suppressor compatible flash hider. The Knight’s Armament SR-15 MOD 2 complete upper receivers feature the URX M-LOK handguards that each have 2 anti-rotation QD sling swivel sockets and even includes a Magpul M-LOK rail cover kit. On top you’ll find the KAC Micro Front Sight and at the rear the KAC 200-600m micro rear sight that is flip up and adjustable for windage and elevation. The included bolt carrier group features the improved E3.2 bolt that has dual ejectors and rounded locking lugs that work in conjunction with the proprietary barrel extension.
