If you’re looking to replace your Heckler & Koch MR556A1 M-Lok handguard with a Picatinny quad rail, this is the handguard for you. The optic mount placement numbers on the top rail are crisp and legible. The handguard comes with the required crosshead mounting bolt. The handguard is of high quality, lightweight, and easy to install. If you have a 16.5” barrel MR556A1, rest assured this 11” handguard will cover and protect your gas piston.
