Try modifying the taclight from the MP5, it has texture.
I will make the Bipod standing then, It will be fittet whit the textures from the XMS not the XM as it is now they look much nicer. it will not have shadow at first because I heard that guns whit over 700-800 polys don't have shadow and this gu has over 2000 polys.
Forest you will get the model that registered_fugitiv has tomorow i just need your e-mail if you don't minde, you can give to me as a message.
