Sure I can.
If you are mentally unstable, you shouldn't be allowed to own a gun.
If you have a criminal record, you shouldn't be able to own a gun.
If you have a substance abuse problem, you shouldn't be allowed to have a gun.
If you have a history of domestic violence, you shouldn't be allowed to have a gun.
To be allowed to have a gun, you need to have a thorough background check. Not just checking a database or checking a block on form.
If you aren't in any of the above groups, you should be able to have a gun if you are licensed, registered, insured, and can prove that you've undergone mandatory training.
Guns with a certain level of lethality (like AR15s) should not be available to the public.
All of that strikes me as very "Common sense".
