KAC SR-25 v2 Lower Receiver + K3 Upper Receiver Package

Product Description

The Knight’s Armament SR-25 V2 K3 package combines the factory-assembled SR-25 V2 lower receiver with KAC’s 16" K3 upper chambered in 7.62 NATO/.308 Winchester. The shorter K3 configuration gives the SR-25 a more compact setup while keeping the features and controls of the V2 lower.

The K3 upper features a 16" 416R stainless steel barrel with 5R cut rifling, a 1:10 twist, and a dimpled hybrid medium profile. The upper is built around the URX-6 handguard and includes KAC’s 7.62 open-prong muzzle brake, which is compatible with the KAC 7.62 QDC suppressor line.

The V2 lower is forged from 7075-T6 aluminum and finished in MIL-SPEC Type III hardcoat anodizing. It features fully ambidextrous controls, a KAC 2-stage match trigger, HH buffer, action spring, A2 pistol grip, and integrated trigger guard.
