great model man! Have you heard of Sketchfab ? We're a web platform for publishing your 3D models interactively. You could upload some of your 3D weapons and add a link pointing to them on Sketchfab in you DA description!
I really like how realistic you make them look, from a design point of view as well as texture/render. The use of detail is restrained and looks like consistent with current design/manufacturing practices.
