The FN 15 Guardian applies the FN battle-proven blueprint to this MSR, making FN quality accessible to all home defenders and sport shooters. Proven to perform on any front, this carbine has the critical upgrades for tack-driving accuracy, with a nitrided 16-inch CMV steel MIL-B-11595 barrel and a 15-inch free-float aluminum handguard. The mid-length gas system reduces recoil impulse with a low-profile gas block impinging gas to the mil-spec bolt carrier. At 6.6 lbs., the light, fast-handling carbine includes the right upgrades for constant control. The pistol grip and magazines are in-mold stippled for superior grip, with the 6-position stock offering a tight lock-up and an ideal cheek weld. A 24-slot M-LOK free-float aluminum handguard offers all the mounting real estate for lights and sights and an anti-rotation pinch-lock design mates to the upper receiver, ready to mount any optic.
