I don't know what to say about the Mini MP5A5, other than it's small enough to hide almost anywhere. At 5 meters it shoots an inch high and almost two at ten meters. I have yet to take it farther. Effective range is still unknown even though I honestly believe it is not too effective past fifteen meters, which isn't an issue really - it is a CQB style weapon. Also it is the kind of weapon you could easily slip in and out of the public with. Like going through a mall. Range becomes less of an issue in an urban environment. Concealability, weight, and employment are primary statistics for the urban battle field. The MP5 takes no kind of intelligence to operate. A KISS simple weapon. Also as opposed to the large battery packs used with most soft air guns, the mini MP5 (and it's cousin mini-models the M16, which hasn't been reliable as the MP5, and the AK-47) uses four AA batteries - another small, easy to find, and highly accessible feature to the MP5. Despite the slight rise in trajectory of the BB the groupings were always tight and never strayed left or right of the target. In the art of covert urban warfare the Mini MP5A5 is a great side arm to have on hand. I would not recommend it as a primary weapon. Continue to read our reviews to find your weapon of choice.
