The Knight's Armament SR-15 is a highly distinctive 5.56 NATO rifle representing the rare Magpul collaboration, identified as one of only 100 examples LOWERS produced. This example features a Carbine Mod 2 upper receiver manufactured by Knight's Armament Company, paired with a 14.5-inch cold hammer forged barrel fitted with a pinned-and-welded four-prong SureFire muzzle device. The barrel is marked with a 1:7 twist and CHF designation. A Magpul URX4 handguard, Magpul stock, and Magpul grip complete the configuration, while the rifle is equipped with a Knight's Armament fire-control group and characteristic SR-15 bolt featuring rounded locking lugs and a dual-extractor system. The charging handle is manufactured by BCM. The rifle does not include sights. The end plate is noted to have provisions for a sling attachment. Overall condition is outstanding, with clear evidence of firing, including residue present within the muzzle device and around the chamber and fire-control group areas.
The SR-15 platform is well regarded for its distinctive engineering and association with Knight's Armament Company, while this particular Magpul collaboration adds significant collector interest to the configuration. The limited 1-of-100 production designation, Carbine Mod 2 upper, CHF barrel, Magpul furniture and URX4 handguard make this an especially distinctive example for collectors of modern American military-style firearms and limited-production collaborations.
