The Firearm Blog tries and give their take on the Beretta MX4 Storm which they say is the most underrated SMG... "In this episode of TFBTV, James Reeves is looking at one of the most underrated SMGs ever, the Beretta MX4 Storm. Like the more tactical version of the Beretta CX4 Storm, the MX4 is light, short, easy to handle, and features a blistering 950rpm rate of fire. This is a massively underrated and reasonably priced SMG. Unfortunately, it’s not available in the USA, but it’s still a fun watch, we promise."
