What's your favourite weapon from Fallout 3/New Vegas?

I was going to make a thread about your favourite weapon from all of the Fallout games, but then most gamers my age haven't played any of the Fallout games apart from FO3 and NV. So instead I just picked that. So what is/are your favourite weapons from Fallout 3 or New Vegas?

Personally, I like a fully modified hunting rifle - it packs a nice punch, it feels very post-apocalyptic & old when compared to some of the other guns of both 3 and Vegas, plus it can be used as an awesome weapon for sniping!

When it comes to my favourite gun, I am stuck between both the hunting rifle and the hunting shotgun. I mean like CrimsonWolf I enjoy the sniping and the looks of the rifle; but the shotgun's a tool of mass chaos and a lot of fun with the correct perks

While I have to admit that I love shotguns in almost all the games that I play, the ones in FO3/NV aren't very appealing to me... somehow.
