This is an interesting high-capacity magazine option for Tokyo Marui (and compatible) MP5 series electric airsoft guns. Though the design is shorter than the 200-round Marui clockwork magazine, it holds a total of 240 rounds.

Appearance

  This magazine is designed to look like two 15-round H&K MP5 magazines clamped together. The details, as usual for Marui, are excellent from the clamp to the fake cartridges sitting in the top of the exposed "magazine." In reality, this is a single bulk BB magazine with a clockwork mechanism similar to Marui's other MP5 hi-cap mag.

Function

  Since this magazine is a double-wide, it can hold a few more BBs than the Marui 200-rounder. It works similarly: Open the trap door atop the "BB magazine" side and pour in BBs until full. Shake the magazine gently and wind up the winding knob on the magazine's bottom. Once this is done, you'll be able to fit more BBs in. After you top the mag off, wind it up some more and you're ready to go. Once inserted into the appropriate airgun, you can rock & roll in a serious manner. Just remember to wind up the magazine periodically while firing; I think it'll only let you get around 50 rounds off before the winder is out. As usual with bulk magazines, this one makes a lot of noise since the BBs are just rattling around. The magazine will let you fire all but around thirteen of the BBs in the mag - once you get that low, the feed mechanism can't lift any more BBs to the firing chamber. But hey, what's thirteen rounds missing from 240? One nice thing about this magazine is that, since it is shorter, you can shoot more easily from the prone position, allowing for counter-sniper work and/or more effective use of cover.

Overall Impressions

  I think my comments from the Marui 200-round mag hold true for this one as well. For our purposes, a 240-round magazine doesn't offer very realistic training, but it sure is fun. It would be a heck of a handy thing to have for fast-attack skirmishes where noise isn't a factor.
