Guys, I know several of you have this carbine chambered in .22lr that resembles an HK MP5.
I know it's made by a German airsoft company.
BUT there is a lot of good feedback on this carbine and few of will ever have the chance to buy a real $4,500 HK94 - civilian version of the MP5.
Conversely, I hear some people are replacing the screws with better hex screws and also installing push pins for easy takedowns and also an improved buffer.
Would be a great present for my 13 year old son.
Seems that if you mount a red dot on top, the irons are useless?
Should I look for the GSG-5 which caused HK to sue GSG for trade dress infringement?
Or go for the revised GSG-522 which notably has different sights, a different selector, different grip, and an awkwardly placed sling mounting point. But it does have a Picatinny rail integrated on top. It is cheaper going for under $400.
What do you guys think and what have you experienced?
