HK MR556A1 Troy Micro Sights Magpul CTR 5.56 NATO Flat Dark Earth Rifle

Description

Product Overview

The HK MR556A1 is a semi-automatic rifle derived from the HK416 and built around Heckler & Koch's short-stroke gas-piston operating system. Its closed piston system keeps combustion gases out of the receiver, helping the rifle run cleaner and cooler in demanding conditions. The 16.5-inch cold hammer forged barrel uses a 1-in-7-inch twist and taper-bore profile for dependable accuracy and long service life. This Flat Dark Earth configuration includes Troy Micro Sights, a six-position Magpul CTR stock, an ambidextrous safety selector, and a top rail ready for a compatible optic.
