Rootin’ Tootin’ Dakka Shootin’
Connoisseur of all things that make very loud noises and lob hot metal at things, Shooty Gulfrag has consistently carried the largest weapon he can physically lift while still being able to clobber gits with it, and only kommon Evil Sun decency (and a desire to keep bullying 'iz Boyz) has prevented him from grabbing a proper snazzgun and going fully Flash Git. Though Kustom Shootas may not be as fancy or as flashy as a mekboy's Kombi- jobs, Gulfrag is of the belief that sticking uvva bits onto 'iz shoota dat ain't more shootas will just get in the way of his enjoyment of the art of dakka, and that skorchas and rokkits are for "no-good fancy gitz 'oo ain't got a brain fer da klassiks".
Yes, kustom shootas are an Index-only option, and they're not as competitive as pure melee Nobz or kombi-skorchas. But they're cool and incredibly cheap, so who cares?
