As a long-time gun owner, I am adamantly opposed to the "Universal Background Check" being proposed by various anti-gun, pro-government restriction groups and politicians. However, I have sold some of my guns and some for a friend who had passed away at local gun shows. I did check to see that each buyer was a State resident and of the proper age. I also personally asked each buyer if there was any reason why they wouldn't be allowed to own a gun. Of course, I was there to sell these guns and not hassle potential buyers. If there was a free (not mandatory) National background check number that anyone, not just a registered Federal Firearms dealer to call just to be sure I would have happily complied. If there was such a service, would you use it? I recognise that this may be going down the slippery slope towards making it more difficult for people to buy guns, but I do background checks on folks wanting to rent property from me.
