I honestly think the fully modded Hunting Rifle is my favourite weapon. It looks awesome and has that post-apocalyptic look to it, and with mods I just love the idea of someone taking a beaten up old rifle and working on it to make it perform better. What a great looking old piece of junk it is.
I love it too and it also comes with the lowest spread of any weapon in the game, but the Paciencia completely made it obsolete to me. I love the iron sights on it and the crit damage is insane.
My favourite gun is without a doubt the CZ57 Avenger. I just finished Hoover Dam for the NCR with it and it mows down everything, the only thing it didn't manage to kill was Lanius and that was just because I was saving Oh Baby for him. As for my favourite armour I'm going to have choose the NCR Courier's Duster. Add the +25 lbs from the Duster with the Burden to Bear perk and 10 Strength and my carry limit was
375 lbs. The Elite Riot Armour is a close second.
