Can't get texture to show up on my object

[Arisen1]

Hey guys...first of all, I am very new to 3d modeling and uv mapping. Basically, I made a basic weapon model, and I had made it as two separate objects. Each object got its own uv map, and the uv maps worked perfectly....the texture showed up on both. Basically, I merged both objects together, and in the process, I also merged the uv maps, but somehow when I merged both of the uv maps as one, I have had trouble with getting the texture to project onto the object. It will export the UV map perfectly, but it doesn't actually update onto the object itself. What is it that I am doing wrong?

As reference, here are the files that I am working on.

If anyone can help, I would be so grateful.
