Item # 164045 Style KNG-31946 UPC 819064016182 Condition New Manufacturer [Knights Armament](https://www.kygunco.com/brand/knights-armament) Model SR-15 Round Capacity 30 Caliber 5.56 NATO, 223 Rem Action Semi-Auto Barrel Length 14.5 in ### Knights Armament SR-15 E3 Mod2 SBR Carbine 5.56 14.5" Black 30rd The SR-15 E3 MOD 2's 14.5” chrome lined, 5.56mm NATO barrel is manufactured to military specifications, features a proprietary mid-length gas system that increases reliability and durability while also reducing felt recoil, and is free-floated inside a 13” URX 4 handguard. An E3 round-lug bolt design both enhances function and increases bolt life far beyond the industry standard. An ambidextrous bolt release, selector, and magazine release offer left-handed users the ergonomic advantages inherent to AR15-based controls. The drop-in two-stage trigger serves double duty as an aid to precision marksmanship while enabling surgical speed shooting at close range. The 5.56mm 3-Prong Flash Eliminator interferes with propellant gas combustion forward of the muzzle to significantly reduce flash signature, will not ring upon firing or when struck, and is compatible with the KAC line of 5.56mm QDC Signature Reduction Devices. #### **SPECIFICATIONS:** - UPC: 819064016182 - Manufacturer: Knights Armament Company - Manufacturer Part #: 31946 - Model: SR-15 - Model: Mod 2 - Action: Semi-automatic - Type: SBR - Caliber: 223 Remington - Caliber: 556NATO - Barrel Length: 14.5" - Color: Black - Grips: Polymer - Capacity: 30rd - Accessories: URX 4 - Type of Barrel: Hammer Forged - Description: 2 Stage Match Trigger, 3-Prong Flash Hider - Subcategory: Short-Barreled Rifles - Stock: Polymer ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
