Heckler and Koch MR556 A4 Features
The Heckler and Koch MR556 A4 .223 Rem, 5.56 NATO rifle utilizes a short stroke gas piston system derived from the HK416 platform to enhance reliability and reduce fouling in demanding conditions. This Gray Cerakote HK MR556 A4 piston rifle features a fully ambidextrous lower receiver with an ambidextrous safety lever for intuitive manipulation from either side.

An M-LOK handguard provides modular accessory mounting, while HK416 slimline furniture maintains a streamlined profile. The 16.5" threaded barrel with 1/2x28 thread pattern supports muzzle device compatibility, and the collapsible folding stock allows adjustable length of pull. No sights are included, allowing users to configure optics to their preference.
