"As Iexcited as I am about this, I literally just pulled it out of the box and hit it up with some flat earth toned paints and have to say, so far it's pretty sturdy. I have an Echo 1 MP5 special black edition ( also painted multicam) , I did have a bit of trouble with the mag release just forward the trigger guard but the mag release button on what would be the ejection port did work to release the Drum. As I can tell with my short time firing it in the yard, I can honestly say there is going to be some shattered egos when a CQB pellet slinger wipes out a squad.
I'd say get one or two, and you'll never run out in a skirmish.
I gave it four stars because though it is great, It is hard to detach from the gun, unless you have tiny hands."
