The red dot on the FAL looks good, followed by perhaps the red dot on the M4. The higher resolution (voxel width) on the M4 (to me) looks better, but I like the look of the FAL a bit more.
Can't wait to see the Rem 700. I'm using the Sif sniper right now, and the SMG is actually an XM8 I found somewhere on the forums that I greatly altered. My shotgun is some halo mod I got and never switched back, as I've yet to find something I really like.
I'd love to see your take on the XM8. Keep up the good work.
