This is another upload of the M82A3 AMR by Amoveve and Alexscorpion. Amoveve's permission to adjust this rifle's grip and positioning.

Version 2.0: Removed the scope and added the scope from .44 revolver to fit this rifle better. Reduced gun model by 10% total and readjusted positioning. Aligned the rail with receiver.

Version 1.5: I have scaled the rifle down by 5% of the size in order to make it fit the player's hands better. I have also rotated the bi-pod 180 degrees to get clear of player's hands. All animations and meshes stayed true to original. The rifle can be found in the underground hideout behind one of the homes in the sanctuary. It can be modified with bi-pod, suppressor and a scope from .44 revolver.

Looking for help in the following: 

Animations
Textures
Mesh Edits
