I need a random favor. (Anyone have a Air Marksmen Backbone not currently on their rifle?)

[KevinWood44]

I am trying to get a good idea of how much, if at all, it will change the balance of my M3 (forward or backwards)

If someone has the Air Marksmen (Long Version) off their rifle can you balance it one finger and let me know where that balance point is?!?


Much Appreciated.
