As one of the most iconic firearms in the world today, it only makes sense that the MP5 would serve as the model for some of the best airsoft guns available as well. While there are plenty of excellent airsoft MP5s to choose from, the Umarex MP5 A5 AEG exists in a league of its own. To help you decide if the Umarex MP5 A5 AEG is the right choice for you, we'll take a look at everything you need to know about this high-quality electric airsoft gun, including its features and specs, a review of its performance, and the history of the real-steel firearm that it was modeled after.

History of the MP5

In 1964, encouraged by the success of its G3 automatic rifle, Heckler & Koch decided to develop an SMG (Sub-Machine Gun) modeled after the G3's design that would be chambered in the 9×19mm Parabellum (9mm) pistol cartridge. This new SMG was first named the HK54 but would later go on to be rebranded as the MP5.

The first major adoption of the MP5 was by the German Federal Police in 1966. From there, the MP5 went on to be used by a wide range of military, police, and paramilitary forces and was a common weapon choice for Green Berets conducting missions during the Vietnam War. Throughout the 1970s, though, the MP5 was still largely overshadowed in popularity by the Israeli uzi. It wasn't until Operation Nimrod in 1980 that the MP5 truly reached iconic status.

During Operation Nimrod, a British special forces regiment of the SAS stormed the Iranian Embassy in London after it was taken over by terrorists. Armed with MP5s, SAS soldiers managed to kill five terrorists and save all of the hostages inside the embassy. Since this operation captured the attention of the world and was broadcasted on live TV, the MP5 experienced a major boom in popularity following Operation Nimrod.

Culturally the MP5 has always been a huge hit. Featuring in so many of the action movies we have come to love throughout the 80's and 90's, it was the movie Die Hard staring Bruce Willis that propelled the MP5 into superstardom! This is not to mention the slew of video games that featured this SMG, such Call of Duty or classics like Rainbow Six.

Today, as a result of advancements in body armor, the MP5 has some stiff competition coming from other SMGs such as the FN P90, H&K's other SMG the MP7, or the latest and greatest from SIG the MPX. Some of these SMGs use rounds that are capable for armor penetration and some are designed to modernize the SMG platform. However, the MP5 nonetheless still remains one of the most recognizable, used, and storied weapons in firearms history.
