Why mount the bipod there?

[docohm]

What is the science for mounting the bipod out near the end of the handguard? If you're using a bag do you put it way out there too?
Inquiring minds want to know....

It’s leverage. Fulcrum and lever stuff. The further out towards the barrel that the bipod is, the less that a specific movement on the butt stock will affect barrel aim. As with most things, there’s a balance though. Too far out on the barrel, such as the very end as an example, and the shooter will have to move too much to shift the point of impact during dynamic situations.

The simple answer is: to reduce excess barrel movement for accuracy, but too far forward can be a negative.

If shooting from a position where bipod placement doesn't matter (e.g. while target shooting from a prone position that's nice and big and flat), I put it out as far as I can where I can still easily reach the feet and cant handle for adjustments. As lash said, the farther out it is, the less small movements at the shoulder will affect it.
