Mach Sakai conducts a detailed comparison between the Tokyo Marui Next Generation MP5A5 and the Evolt M4 with Recoil. He examines the MP5's physical build, noting its weight of 2.84kg and its functional features like the 72-round magazine and adjustable sights. He takes the time to demonstrate the battery installation process using a LiPo battery and explores the tactile feedback of the selector and charging handle, which allows for the famous "MP5 slap."

The testing phase involves shooting at targets from 15 meters using various BB weights, ranging from 0.2g to 0.28g. The MP5 shows off its recoil system and auto-stop feature, which kicks in when the magazine is empty to mimic a real firearm. While the initial muzzle velocity seems a bit modest, the consistency and trigger response earn points during the steel challenge and precision shooting segments. It seems the gun is more interested in hitting the target than breaking any land speed records.

In the head-to-head matchup against the Evolt M4, both airsoft guns demonstrate decent accuracy, though they each have their own personality when it comes to recoil and handling. The Evolt M4 provides a different kick, while the MP5 remains a solid choice for those who enjoy a bit of mechanical drama with every shot. By the time the 0.28g BBs come out, the performance levels stabilize, proving that sometimes a little extra weight helps keep everyone on their best behavior during target practice.
