| Seesaw (Lever / Fulcrum) |
A
fulcrum is the support about which a
lever pivots. In the case of
Accuracy Solutions logo, the old man has his board (lever) pivoting on top of a mountain (fulcrum). This illustration is very similar to a playground toy most are familiar with, a seesaw, except for the position of the fulcrum. The reason the old man slides his lever over towards the far end of the lever is to gain maximum leverage so he can "Move the World".

This same principle can be applied to the shooting world. An existing device that most shooters own, a bipod, is nothing more than a fulcrum and the rifle a lever. Instead of the pivot point being at the point of the triangular shape, like the seesaw, its pivot point (resting point) is where its two legs touch the ground. The pivot point is at the base of the triangle in this case because bipods are rigid at the point of attachment (except for canting correction) whether a sling stud or pic rail install.
Inherently shooters have been achieving greater leverage with the wide adoption of tactical style rifles which have created modifications to extend pic rails closure to the muzzle of the rifle. Instead of positioning their bipods towards the center of their rifles where a traditional bipod attachment lies, they have been leveraging the longer attachment points and have slid their bipods closure to the muzzle for many years. The advantages of extending the pivot point are great. The results being increased stability and accuracy through less movement being transferred through the rifle. Reticle shake is minimized as well.

In the case of the seesaw where the pivot point is in the middle, one foot of movement (input) on one side of the lever will be consistent with the other side (output). Now the old man can move his side of the lever and the other side will move a fraction of that based on the pivot point. This decreased movement is multiplied the longer the lever is.
Rex Reviews explains the advantages very well. "Increasing the length between the end of the lever, where you are manipulating the toe of the lever, and the fulcrum, which is the bipod; the longer that is the more movement it takes on the far end, the stock end, to translate that wiggling into the crosshairs. So it really really helps. Not even exaggerating it makes it twice as good or three times as easy maybe more, it’s hard to quantify this but I will certainly tell you it makes it way easier to stay steady.

| BipodeXt Can Extend the Resting Point of Your Bipod to the Muzzle of Your Rifle and Beyond |
With limitations on the length of rifles, bipod attachment points have been limited as well, until now. With
BipodeXt it extends the pivot point of your bipod by adding approximately one pound of additional weight. Benefits include a reduction in muzzle jump upon firing, less movement transferred through the rifle, reducing reticle drift and wobble zone.
