I just cant believe you on this, the recon is only slightly more modable than the maverick. I've seen people put beefier springs in the back,remove the air restrictors, and not use the front barrel and only get fifties to sixties range angled.
Regarding the stop sign, (if you would ever feel compeled to pretend that you were an evil zombie clown).
Your stopsign looks stragely alot like the evil clowns from the madness games if you wanted to you could use it as part of a corstume.
