Soft Air GSG Full Metal Blowback AEG Airsoft Gun, Black
This modern looking submachine gun is part of the new full metal GSG-522 series from Cybergun.  There are many things about the 522 which have been updated from the preceding GSG-5 to include a completely new streamlined polymer lower receiver with stipple textured grip. The upper receiver has been fitted with low profile sights and it now has an integral rail so you no longer need a special claw mount in order to attach an optic. These airsoft replicas have been cloned after the more modern two piece body so the upper receiver can be separated from the lower receiver by simply pushing out a series of pins which makes maintenance a much easier task. They are also compatible with TM Spec MP5 magazines so there are no issues finding spare magazines for these models.  The GSG-522 RIS features a UMP style side folding skeleton stock which features a rubber cheek rest and butt pad. Pulling back the charging handle on this model pushes the mock bolt to the rear and gives you access to the internal hop-up adjustment lever. Inside of this gun you will find a Version 2 gearbox fitted with steel gears running on steel bushings as well as a steel core spring guide with bearing so this gun comes very well equipped right out of the box. However, the coolest feature this model has to offer is its blow back system which drives the bolt back with the piston every time the gun fires. Squeeze off a round and the solid aluminum bolt is thrown back sending the recoil through the stock and into your shoulder with a solid jolt.    Even though the affects of the recoil on full auto does realistically make long distance shooting a little more difficult, the gun is actually surprisingly accurate given its compact size. It is also quite powerful with a muzzle velocity of 400+ fps so it can easily connect with targets out to 60 yards away.  Do not use with .12g BB's, this gun was made to shoot with .20g BB's or heavier.
