The HK 416 A5 is a newer development of the HK416 assault rifle. Big changes made, both from the previous version and what’s available on the market today, maximize safety, reliability, ammunition compatibility, and durability. Changes to the 416 include an improved tool-less gas regulator for suppressor usage. HK also redesigned the lower-receiver to be user-friendly, which allows ambidextrous operation and optimized magazine compatibility.
