Primos or Vanguard? Why?!

Intenseaty22' I would think that could work, I can only use a Bi-Pod for hunter class so that's what I bought. It will depend how the third leg is attached to the trigger mechanism, I can't honestly say i don't remember much as I was so mad when I cut mine down only to find you can't just cut it off as the way it works prevents that from working properly!! Good luck!! J.L.
