This has been my project for the past few days.
It is a 12g double barrel boxlock shotgun that has had the stock and barrel sawed down. It is tightly based off of the Savage Arms Stevens 311-D. I went freestyle on the design where I couldn't find good reference material, and left out many details that would go unseen in conventional use. I unwrapped and textured it to the best of my ability, and included what I hope is a working normal map (Slow rendering prevents me from previewing the maps efficiently, so I had to cut corners). it is rigged with bones to control the rotation of the barrels and the release switch, with separate bones for all 4 shell models. The extractor is static to the barrel in the out position, but it is floating.
I don't expect great scores. Maybe it's because I made it from scratch, but I can spot dozens of eyesore errors in the texture and model. I had fun making it though and maybe someone could fix it up or use it as a base for their own model. .BLEND and .OBJ... .OBJ is NOT RIGGED (sorry), but individual components are floating. Includes optional high-res version of the shells, requires remapping.
I have to jump off for a while again so I can't answer questions, but please flag it if something is wrong. A very ridiculous but popular knife model is next.
