Well, while I am not a fan of big brother legislation, I fail to see how this will affect the average gun user (hunter, sportsman) other than cost. The cost part sucks. I think if money is recovered in a crime involving guns, the victims should get part of it (if possible) and part should go to offset costs of tagging. It sucks that 99% of responsible gun owners have to finance this effort for the 1% who do bad things.
Laser tagging is coming soon for use in cars and other expensive items to make it harder for criminals to hide the evidence.
Also, if this legislation fails to enact nationally, then ammo sales in states that have the etching will nosedive and correspondly rise in states that do not have it... making the law another farce. I find it hard to believe it pass in states like mine (Alabama).
