OK, here's a idea I haven't heard anyone propose, but since we're in the mode of "compromise that constitutes a win", how about this:
We agree to something the Left has been pounding the table for for years, universal background checks, but in return the requirement for the NICS check to be done by an FFL is dropped. I mean, the check involves nothing more than a phone call and a form that takes all of two minutes to fill out...why does a license holder have to do it, and why do we have to pay for it?
So, you want to give your college-age son a rifle for Christmas? Easy: make a phone call. Want to sell a guy at your club your .50AE with eight rounds through it? Make a phone call. The Left gets their universal background checks; we get simpler lives, saved money, and the chance to prove that the checks will accomplish nothing.
