The M134D-H Hybrid Gatling Gun is the standard lightweight Minigun design from Dillon Aero. The Hybrid Gatling Gun combines the titanium and skeletonized parts that were originally engineered for use in the M134D-T titanium Gatling Gun with the steel housing of the M134D steel Gatling Gun. The Hybrid gun was designed to offer the weight savings of the titanium gun and the longer service life of the steel gun. The Hybrid system is only two pounds heavier than the original titanium gun, is between 10-20 pounds lighter than the steel system, and has a service life of 1,500,000. The M134D-H is in widespread use in both Crew Served and Fixed Forward applications.
