Upload the files on 4Shared, send the links to me and I'll pep them and tell you if they are easy, med or hard

I need alot of practice if I want to build a suit xD
So ya.....
But I have the question
Is the sniper rifle (SRS99D AM) in question the sniper rifle in Halo 1, 2, 3, or Reach?
I'd rather it be the Reach one, but it's fine lol
Edit: The file is very huge, (I opened it in MilkShape 3D 1.8.5) to try to mod it by adding a few vertexes on the sides to make them editable in 2 pieces in Pep, but since it's too big, i cant find where
Im going to try in Google Sketchup, since that's what fat-hi555 used to make it
Edit again: 3DS Max doesn't work either so I've got 2 more options: sketchup and Blender
Edit 3: Sketchup doesn't work
Im going to try to talk to fat-hi555 to see if he could mod it
