This is a 100% custom rifle meaning I bought each part individually to build it. It has a prommy perfect chamber hop up, purple bucking, orga barrel and p* engine. This is top of the line internals and the gun looks great externally. The stock is polymer and the outer is aluminum so it is still relatively light. It is impossible to find a hpa sr25 unless you make it yourself because you have to modify the engine in order to have it fit the lower receiver. I am a airsoft tech so all the work was done correctly, I know what I'm doing. Comes with three mags. Suppressor not included. Just cleaning house so make me an offer and I'll probably accept.
