I'm not sure why, but I can't open any of your models in Blender. My ratings are based on the project page, textures, and the wip screenshots you sent.

I really love the Sci-Fi look of this, the colors are good, and it has really good details. Topology and UVs look good, and overall, this is a very solid asset that I would love to see used in a game.

Small note, I put considerable care into the magazine, base gun, and supressor. I have considered these seperate tools for the submission since they can be used interchangeably with any future models I create for a game. I understand if that puts me down a few pegs in some people's eyes though.
