Description
Product Overview
The Heckler & Koch MR556A1 M-LOK is a civilian semiautomatic rifle derived from the HK416 platform. Its proprietary short-stroke gas piston system keeps propellant gases out of the receiver, helping the rifle run cleaner and cooler than conventional direct-impingement designs. A cold hammer-forged 16.5-inch barrel provides durable performance, while the free-floating M-LOK handguard supports accessory configuration. The adjustable synthetic stock accommodates different shooting positions, and the threaded muzzle accepts compatible 1/2x28 accessories. Chambered for 5.56 NATO and compatible with .223 Remington ammunition, the rifle includes one 30-round magazine.
Key Features
- HK short-stroke gas piston operating system helps reduce fouling in the receiver
- Cold hammer-forged 16.5-inch barrel delivers durable accuracy and service life
- M-LOK compatible free-floating handguard supports flexible accessory mounting
- Picatinny top rail provides a solid platform for mounting an optic
- Adjustable synthetic stock helps fit different users and shooting positions
- Ambidextrous manual safety supports convenient operation from either side of the rifle
The HK MR556A1 M-LOK combines HK416-derived piston reliability with a configurable modern rifle layout for training, recreation, and demanding range use.
