Description
Product Overview
The HK MR556 A4 is the commercial AR pistol variant built around the operating principles of the HK416/MR556 family, using a short-stroke gas piston system for reduced fouling returning to the action and smoother long-run reliability. An adjustable gas regulator lets you tune operation for suppressed or unsuppressed use, while fully ambidextrous controls and a slim, easy-to-manipulate layout help streamline handling.
Key Features
- Short-stroke gas piston system helps reduce carbon fouling in the action
- Adjustable gas regulator for tuning performance with or without a suppressor
- Fully ambidextrous controls for left- and right-handed use
- M-LOK free-float handguard for modern accessory mounting options
- HK USA Enhanced grip for improved control and ergonomics
If you want an AR pistol platform with HK build standards and piston-driven reliability, the MR556 A4 is built for it.

One of the best AR15...
One of the best AR15 style rifles ever made. Way lighter than the previous MR556 A1 variant. Handguard is way better, and doesn't require tool to take out pins for lower receiver. Perfectly gassed, way smoother shooting both suppressed and unsuppressed. Capable of 1 MOA or better with right ammunition. Expensive, but well worth the money. Shoots better than my mk18, and runs cleaner and cooler.
