HK MR556A1 Competition .223 Remington Blue/Black Rifle

Description

Product Overview

The HK MR556A1 Competition is an MR556A1-based rifle built with input from competitive shooters to support fast handling and dependable operation. It features a 14-inch Modular Rail System (MRS) that stays clear of the barrel for a free-floating handguard feel while providing a light, flexible setup for match accessories. An OSS compensator replaces the standard flash hider, and the rifle uses HK’s long-service gas piston system to improve reliability and reduce fouling. The standard MR stock is upgraded to a Magpul CTR-style 6-position collapsible stock for secure, smooth adjustment during competition and practice.
