loved this setup
quad barrel, canister mag, accuracy stock{doesn't matter which one}, 5 times burst trigger, sword bullets, i had silver grip the actual setup (hail-fire) has "cool guy grip"
i'd also recommend changing the stock to something like sticky bees stock to deal with walls, as well as using the rubber grip instead of cool guy or silver
and finally if you think your computer can handle it id recommend using shotgun shells or ghost rounds instead of swords
