AEG Hopup question....
Not that I have an AEG, but I just found out that GHK AKM GBBR uses AEG hop-up. The stock one looks torn when I when changing out the outer barrel. I am looking to use some replacement. The stock one seems pretty soft, what kind of AEG hop-up is something that maybe harder rubber, closer to what you might typically find in a GBB?
