No, not recommended... Those rifle attachments are just plain attachments... The Sharp Shooter is a much better attachment, it's not just any attachment, it has internal circuits to "relocate" the buttons. For instance, the Move button is in the middle of the Move controller and it's used to "take cover" in Killzone 3. If you use any other rifle attachments, you can't "take cover" easily, not in awkward positions anyway. The Sharp Shooter has relocated the Move button right on the gun handle (where the trigger is). You can easily take cover and fire Also, with the Sharp Shooter, there's a physical reload button at the bottom of the "magazine." Reload? Just slap the bottom of the mag :lol: or clockwise the Move controller...
Do not get those crappy rifle attachments if you're going to play KZ3 or SOCOM 4.
