The stats on the base weapon really promote leaning all the way into a crit build. [Lethal Momentum] helps this by making shots get there faster, and Galv Crosshairs synergizes with it. No Galv Shot because I don't think the status is there to make it work without primers, which I'm not a fan of.

Can remove Torrent to do viral/heat or corr/heat if desired, or leave it and run pure corrosive or radiation. Single element, it's probably best kept as radiation for killing alloy armored jerks
