About this product
The MR556A4 is Heckler & Koch's semi-automatic civilian version of the HK416, the short-stroke gas piston rifle used by special operations units worldwide. The piston system keeps carbon out of the receiver, the cold hammer forged barrel is rated for exceptional accuracy and life, and the free-float Modular Rail System handguard is HK's own. Chambered in 5.56 NATO, it ships with an HK 30-round steel magazine where legal.
