holy crap.... i don't know were to start... maybe with this, no offense, but you just undermined my faith in humanity some more. 1) there is no sniper class in airsoft. Airsoft is not COD. 2) It is a sniper RIFLE, not a sniper. 3)I would say go for it if you Know what you doing. And, on the subject of a body, you just need to make a shell, you can remove every part needed to make the rifle function from the original body and put it in a new shell if you know enough about airsoft gun smithing. I personally am not an expert, but I have seen some pretty neat body mods for airsoft rifles and would say this could work. And, on a closeing note, I doubt your friend had an actual airsoft sniper rifle because at 20 yrds. it would have left quite a bit more than a welt.
