I also urge people to not look at the line that says
* Grandfathering weapons legally possessed on the date of enactment
* Exempting over 900 specifically-named weapons used for hunting or
sporting purposes and
* Exempting antique, manually-operated, and permanently disabled weapons
You might look at that and say "I already own this or that so I'm ok." or "I have only pistols for sport and hunting rifles" or "I only have guns that my grandfather gave me" but I assure you there are more unknowns in there with the wording on the first page. While you might not be directly affected with what you have now, what if you want to buy a new deer rifle and it has a box magazine? Maybe they tell you no, or a nice trap or skeet gun and since it has some special sight on it it might be classified as a "military characteristic".
This is bad, even if what you have will still be legal and ok for your possession today, tomorrow you might have problems getting everything.
