airsoft systems mosfet and prs stock

[W0lf]

quick question. im building a dmr out of a king arms m4 base gun. it will have an airsoft systems smart control unit mosfet and i would really like a magpul prs stock for the looks and adjustability. however it looks like you can just about get a lipo battery in there and the mosfet would take up alot of room in the buffer tube. anybody with this set up or at least a prs stock know weather it will fit or not? thanks
