The Wunder-Bar Mark 4 M414660BSM3 is a 14-button post-mix bar gun built for high-volume cocktail and soda service. Six carbonated buttons handle your branded sodas, six non-carbonated buttons cover juice and mixers, and two flex lines round out plain water and soda. The Mark 4 platform is the industry workhorse: pour speed, lever feel, and trigger response all calibrated for fast-paced bar service.

Compatibility

Drops into any standard Wunder-Bar Mark 4 line set. Hose pulls QD fittings, so swap-out for service takes under a minute with a Mark 4 manifold. Compatible with standard BIB (bag-in-box) post-mix syrup feeds and most CO2 and plain-water lines used in commercial bar setups.

Why a Mark 4

The Mark 4 series has been the dominant post-mix platform in American bars for two decades. Parts are widely available, every distribution tech knows the platform, and the lever action holds calibration through years of service. Service techs report Mark 4 guns outlast newer competing platforms in heavy use.

Service and Parts
