"Got this in the mail today and it is exactly what it says. It is a stock hop up unit to replace damaged ones (I broke my old one when I took out the inner barrel). Works just like the one that the gun came with. Word of caution though, it comes in pieces that must be assembled but that is a trivial matter if you have even half a brain. Good product overall.
