    What is the build quality like? Is this simply an HK GSG? I.e. an airsoft shell with a rifle jammed inside? I’ve got to say the MP5 SD series have always caught my eye and so if this model is priced right I might just have to pick one up. Nice presentation btw, a very nice scientific presentation of pure fact.


    • Thank you. We loved the gun!!! I have a write up coming out here very soon which will go over all of your questions. It is worth picking up.
