Using the HK MR556A1 as the platform to build a competitive rifle , the Heckler & Koch Competition Model was developed for both casual shooters and the most demanding competitor. Ideal for 3 gun matches the Competition Model adds the most critical fundamental enhancements to the standard MR rifle. Foremost among these additions are the new 14-inch Modular Rail System (MRS). Lightweight and easy to customize, the MRS allows sections of accessory rails to be added by the shooter where desired, but keeping weight down and presenting a more ergonomic and comfortable handguard surface when compared to rectangular full rail systems. An extended magazine release is also included for quick magazine changes. Its innovative compensator by Operator Suppressor Systems Inc. (OSS) replaces the standard MR flash hider. OSS is a leader in the development and manufacturing of sound and flash suppression and uses technologies originated in those fields to create a unique and highly effective compensator. The MAGPUL CTR buttstock is easy to adjust, the stock moves smoothly on the receiver extension and locks securely in position. Its profile and weight make this buttstock ideal for competitive shooters. It features a German-made long service barrel produced by Heckler & Koch's famous cold hammer forging technology and H's famous piston operating system this system uses a gas piston and pusher rod in place of the more common hollow gas tube normally employed in "direct impingement" AR-style rifles.
