think about it this way, by using that you make it so that everyone isnt having fun. Just you. now look at supply and demand. What if EVERYONE went a bought one of these? Nobody would be out, ever.
By looking for loopholes your taking away the fun in the game
the only ones that this product would help from being hit, would be the ones that learned how to use it properly.
all others it would hinder and get them killed, (personl experience).
and it would not stop any players that are agresive from being agresive.
useing this product on my gun only slowed me down a lil bit.
i can see this product as helping to cause damage to the users optics though. you are not compleatly behind cover when useing it.
you will have your hands and possibly arms exposed durring use and if your gun is the only thing you stick around corners your gun will get shot at and you take a higher risk of it a your optics getting hit.
