The receiver is cast metal instead of machined, forged steel. The internal parts are cast or stamped wherever possible. The barrel band is PLASTIC and breaks with a frustrating regularity. The few places where machining is done, it is done roughly. Tolerances are sloppy.
I don’t have a dog in this fight. I just call it from a machining, metallurgical and mechanical standpoint. The Henry is cheaply made and overpriced. The result of the differences between the two are that the Henry will experience more frequent breakdowns than the Marlin when fired at the same round count rate over a given period of time. The fit and finish on the Marlin is also vastly superior. Heck, the Henry is painted for goodness sake.
