Let me begin by saying that if you are in the market for an all metal, quiet gas submachine gun, with semi auto, you might as well keep looking. However, if you don't mind some plastic, and a whole lot of noise, this is a very sweet airsoft.

Realism

     Unfortunately, not much in the feel department. This gun is mostly plastic, and if that isn't enough to ruin your day, the fact that the clips say MARUZEN M11 on the bottom is. In the looks department, it is actually quite accurate. The trademarks are wrong, but the look, dimensions, and overall appearance of the gun is dead on.

Functionality

     This gun is a gas blow back with some serious kick, and some serious noise. The bolt blowing forward and back is enough to lay heads down from clear across the field. Even with the homemade silencer (see the Upgrades\Technical section) the gun still makes some crazy noise. If you can look past the fact that one shot gives your position instantly away, you will quickly see that the gun is surprisingly accurate for such a short barrel, and has a bit of range to boot. 

Usability

     I have personally carried this weapon into combat, and was very pleased with the results. The gun, while made of plastic, is very durable, and easy to carry. At the time I used this gun, the silencer had not yet been crafted, so the gun was even easier to transport. The cocking mechanism is very easy to use, the top middle sight pulls pack to lock the bolt, and after, ONLY after it has been cocked, the mag slides in easily, and the gun will relinquish it's grasp on 50 BB's shortly. Slamming the mag with the bolt closed can seriously damage the bolt mechanism. 

     The gun fires reliably aside from one problem I will address later in this review. Each shot is consistent, and despite the lack of semi auto, gas is used efficiently. I can get 2 to 2 1\2 clips of BB's per fill depending on the weather, etc. 

GBB Submachine Gun Mag Problems

     As with almost all GBB SMG's, the Micro Uzi suffers horribly from mis-loaded BB's. When loading the magazine, you must ensure that each BB is properly seated in the double stack pattern. A missed BB will cause the bolt to stay forward or misfire, requiring you to re-cock the gun, sometimes even drop the mag and reinsert it. 

    Also to be noted, I have 3 mags for this gun, and each mag suffers from the same problem. If the spring on the mag is not WELL oiled, it will not feed the last 10-15 bb's correctly, resulting in inconsistent spotty fire during the end of the mag. This can however be easily fixed with some oil or grease. 

Silencer

     The silencer on the uzi is homemade, and if you want the details on it, they will be posted shortly in the tech\upgrades section.

IMO Opinions

     The Maruzen Micro Uzi is a very competent, useful gun to take to a skirmish. I will carry it into every situation I enter in the future. I do not recommend this gun as a primary, unless you are in a GBB war only, in which case this could be a very good choice. However, as a emergency backup, or when you just need a gun in each hand, this is a great choice. Upon some research and real life testing, with the right gas, this gun will actually out fire the MAC 11.

If you are considering buying this gun, also check out the reviews on the MAC 11, and the Steyr TMP.
