Does such a thing exist? If so, point me at it or hook me up with it and I'll appreciate it.
I don't recall ever seeing one specifically, but, you may be able to skope Lord Emsidy's "Crimson" mesh onto the Male Basic Rifle.
I have 2 possibilities. Xcom_female_light_rifle by JIK. Has parts which can be hidden down to female_bald or female_basic_rifle by atticboy. It has female_basic as its base but female_bald could be skoped in. Atticboy's mesh seems to use male_basic_rifle keyframes. Jik's is unique. Let me know which one and where you want it sent and I'll be happy to get it to you.
I didn't know that about Jik's mesh.
Thinking about it though, there would probably be a lot of uses for Female Rifle with Female Bald scoped on (beyond my making a bunch of female SHIELD agents). If you would, could you send a scope of Atticboy's mesh to lonespaceranger@gmail.com?
I'm going to look at Jik's meshes, though, for another project I'm thinking of.
