I saw another one before that I thought looked remarkably like the HL2 magnum, also for shooting iPhones.
I actually thing these scams are useful.They expose and rob the ones stupid enough to grab the bait. Regarding the TF2 pistol use , i think VALVe should sue.It is copyright infringement
On those "Free FPS" advertisements I constantly see, the M4 Carbine is clearly stolen along with the Deagle, and used in the advert.
I used to see versions of these with COD4 hands etc. They always do it because it is easier than creating their own. Sue.
