Manufacturer Description
The MR556 A4 is a short-stroke gas piston, semi-automatic AR-pattern pistol chambered in 5.56 x 45mm. It uses a rotating bolt and accepts STANAG/AR-pattern magazines; the 11" pistol SKU is supplied with a 10-round magazine.
Factory features include a match cold-hammer-forged barrel with concentric 1/2 x 28 suppressor-ready threads, an adjustable 2-position gas regulator for suppressed/unsuppressed use, and fully ambidextrous controls (safety, bolt release, magazine release, and extended ambidextrous charging handle). The MR A4 also includes a continuous Picatinny rail interface between the upper receiver and handguard and an M-LOK handguard for accessory attachment.
The platform ships with a multi-position adjustable buttstock and HK-enhanced ergonomic grip; the barrel bore is backed by HK's lifetime bore guarantee for A4-series firearms.
