Heckler & Koch MR556 A4 Review: The New 2025 Evolution of the HK416

Heckler & Koch MR556 A4 Review: The New 2025 Evolution of the HK416

Description
We are testing the highly anticipated Heckler & Koch MR556 A4, the 2025 update to HK’s legendary short-stroke gas piston platform. Patterned after the world-famous HK416, this A4 model introduces a 2-position adjustable gas block for seamless suppressed shooting, a fully ambidextrous lower receiver, and a slimline M-LOK handguard. We hit the range to evaluate its 16.5-inch cold hammer-forged barrel, improved ergonomics, and "over-the-beach" capabilities. See how this premium German-engineered rifle handles recoil and precision strings, and discover why the MR556 A4 remains the gold standard for reliability and performance in the high-end AR-15 market.
