Updated 12/1 with sci-fi project render. Thanks for all the crits and advice. There is no target really for this project, just a portfolio piece and learning mostly, it's for my final senior projects at school.
The UTAS UTS-15 is a 12 gauge pump-action shotgun with two 7-round magazine tubes that can feed in an alternating or selecting pattern. Modeling in Maya, Textured in Substance Painter and Marmoset Toolbag 4, Videos rendered in Toolbag. Hope u like it! https://www.artstation.com/artwork/14ln2L
