Heckler & Koch HK416
$1,470.00
Description
The Heckler & Koch HK416 is a modern 5.56×45 mm NATO assault rifle developed by the German manufacturer Heckler & Koch. It improves on the classic AR-15/M4 architecture by using a short-stroke gas piston system — derived from the H&K G36 design — instead of traditional direct-impingement gas operation, which helps keep the action cleaner, cooler, and more reliable under harsh conditions.1 The HK416 is trusted by many special operations forces and national militaries, and offers modularity, ambidextrous controls, and broad adaptability with varying barrel lengths and accessory options for different tactical roles.
