It isn't about "just guns". I couldn't give a squat about getting rid of a gun, or a few hundred; it's just a chunk of metal. But it symbolizes a right that guarantees other rights.

I have a Mosin. Mostly like it cause its big and cheap to shoot. Got the rifle and 800 rounds for $200. Cheapest AR I can find is over a grand, and that don't count ammo.
