45 years after the first MP5 was built in Germany the long-awaited Airsoft gas blowback ist available now. The Umarex gas blowback MP5 has full proper licensing between Umarex and H&K, so that means that the weapon's design and markings are spot on.
What sets apart the SD versions is the silencer. The model was first introduced in 1974 and it is an iconic model that was made wordlwide famous by the members of the SAS troops.
The upper part of the receiver is made out of stamped steel, with the barrel, sights, retractable stock, etc being metal. The only non-metal parts are the polymer lower trigger housing and the handguard, with high glass fiber content making it extremely close to the original.
The removable dummy silencer hides a 320 mm inner barrel and it ads the needed amount of weight to match the read deal MP5SDs.
As a metal GBB SMG, it also weight distributes similar to the real thing as the furniture is real and metal distribution is similar.
The model bears the everlasting HK sights like the one found in the G3, G33 and 416 models. The rear one is adjustable for various ranges from short to long distances.
The selector lever on the receiver has three settings for Safe, Semi and Full Automatic function. The lever rotates and it sets in each position with a very distinctive click.
The operating system is identical to the real deal one. The user has to cock the charging handle to load the first BB. When the magazine is empty, the bolt locks to the rear to indicate that it must be changed. After change, rack the charging handle again and you are ready to Rock N Roll.
The 30 round real capacity metal magazines houses the gas needed to operate the system. The gas reservoir is more than enough to cope with the cool down whilst emptying the magazine in either rapid or full auto fire.
As if it did not just look good on paper, it also kicks like the very best GBBR Airsoft guns out there. If you are big fan of MP5s and are looking to get an top-of-the-line GBB model then look no further, you would be hard pressed to find a better model than this one, short of the real thing.
