I have to agree with all that was said here but i do have some different ideas on the subject as well.
I've just picked up an mp5 blowback, I'll be testing it this weekend and checking out what it's made of. I'll update after that.
As of right now with a few shots fired it has a good sound to it, and sounds like it has a wicked hit. I can't wait to chrony it.
Updates to come.
