I have bought some of these stickers and speaking from someone who used to manufacture and apply graphics to racing cars, these are as good as you could find or manufacture.
As a Venom owner I completely understand the concerns of the Venom community and yes, there are some individuals currently "assembling" Venom guns on various sites for purposes unknown.
Of course, fake Venoms will get by the unwary, but for those who have done their homework, a fresh sticker is not the decider for handing over serious money.
There are ways to confirm a true Venom rifles authenticity and like buying a car, condition, history, and mechanical inspection are all serious pointers to a genuine buy.
These stickers could have been reproduced for many years under the radar and it is likely they have been. Any professional faker will already be at work and not waiting for these to arrive on the market.
I for one am not worried.
