Some would argue that the socom is not inferior to the beowulf...They are very similar in ballistics so I guess its just a matter of cost. Plus I believe the ammo is more expensive for the Socom too, and the Socom uppers are more expensive unless you got in the group buy....
Why I went with the Beowulf:
[B1. the upper is machined to the beowulfs specs and you dont have a smith grinding on 5.56 upper to make it work. 2. Chicks Dig the .50 cal 3. Ammo is cheaper 4. I can get the Uppers for Dealer price
