To order the ISIS Eye Dominance Rib Attachment, print out and complete this order form – Eye Dominance Rib Attachment Order Form and email the completed form to us.

To attach to rib:

  • Thoroughly clean top of rib with surface cleaner provided (wipe thoroughly in one direction only).
  • Remove adhesive protective paper and push onto rib approx. 20 mm back from end of rib.
  • If you wish to try different bead colours provided, remove protective paper from base of bead and push into central slot about 5 mm back from end of rib attachment. If you decide on a colour, remove bead from attachment, scrape off adhesive and carefully attach with a small amount of adhesive such as Loctite.

Does it work?

  • Right handed shooter/right shoulder gun mount
  • Mount gun
  • Close right eye
  • Bead not visible with left eye
  • Opposite for left handed shooter
  • Slight recess down centre of attachment to help with central eye alignment

Head Lifting

Shooters react instinctively to the recoil of a shotgun or rifle and in most instances that reaction has a negative effect on our ability to hit the target consistently. One of the most common reactions is moving the face/cheek away from the comb of the stock as the trigger is squeezed. Better known as 'head lifting' this almost invariably results in the shot going 'high' in relation to the chosen point of impact.

Head down

This photo shows the jaw bone (A) and the cheek bone (B) when the face is positioned snugly onto the comb along the line (A) to (B).

This location of the face ensures consistent eye/rib alignment, shot after shot.

Head Lifted

Here we can see the position of the jaw bone (A) and the cheek bone (B) when the face is angled so that the recoiling gun does not hit the shooter in the face.

This position is frequently seen on shooting grounds worldwide. The shooter feels a firm location at (A) and is happy the gun mount is correct. However the line (A) to (B) should be located along the comb to give a repeatable eye/rib alignment.

Note the position of the interconnecting line between (A) and (B) when the head is lifted. This line shows the angle that the face is rotated upwards from a pivot point just below (A), resulting in the shot being high on the target. When the head is down, the line between (A) and (B) remains parallel with the gun ensuring an accurate aim.

In addition, with the head lifted, (A) is the single pivot point and therefore the face is free to roll over or away from the comb when the gun is swung to the left or right. With the head down, both points (A) and (B) are snugly against the comb keeping the face in a fixed position relative to the gun, no matter which way the aim is swung.

Head lifting, in the majority of cases, is caused by a 'self preservation' reflex to stop the comb of the stock hitting the shooter in the face.

Most shooters are not aware that they lift their head to some degree, on virtually every shot. This variable position of the face on the stock and the subsequent variation of the eye to the rib of the gun leads to more missed targets than any other cause.

When the gun is mounted correctly and the cheek located snugly onto the front half of the comb, a face, eye and rib location is created which can be repeated consistently each time the gun is mounted and fired. This will stop the shot not only going high, but also to the side of the target by eliminating the face rolling over or away from the comb.

The only way to stop the reflex of head lifting is to smooth out the facial recoil experienced by the shooter. The face can then be consistently placed on the same place on the comb, giving the same rib/eye relationship shot after shot, without fear of any discomfort from the recoiling gun.

The design of the unit, using the latest technology in materials allows the shooter to experience smoothness in facial recoil surpassing anything previously experienced.

By keeping the face in contact with the comb before and after firing a far greater degree of accuracy can be achieved. The ability to do this is very advantageous for the serious competition shooter.

Eye / Rib Alignment

The serious competition shooter knows that in today's highly competitive sport, the need for consistent eye / rib alignment is critical in minimising the number of missed targets. Just a few lost targets means a position a long way down the leader board.

With the ISIS Facesaver Comb, it is possible to overcome head lifting and keep the face snugly on the comb, shot after shot.

To ensure consistent accuracy, a rifle shooter using open sights places the front bead in the aperture of the rear sight to align the barrel and then places the front bead onto the target. This alignment ensures that the bullet is fired where the front bead is pointing as seen by the shooters eye.

This alignment does not rely on the face being in contact with the stock in any particular place or position. Repeatedly hitting the target relies on the alignment of front and rear sights.

A shotgun shooter has to use his eye as the rear sight in order to consistently hit the target. The eye has to view the bead down the centre line of the rib. The bead or the centre line of the eye / rib alignment is then placed at the appropriate place in relation to a moving target and the trigger is pulled.

Whether we see the bead consciously or sub consciously or have no bead and rely on eye / rib alignment does not matter, the crucial factor is that the eye is looking down the centre of the rib at the target or at the relevant point in front to obtain a correctly placed shot. The only factor important to consistent eye positioning on a moving gun is where the face is located on the stock.

Any ideal location needs three points to give guaranteed repeatability. Unfortunately shooters only have two points available to ensure repeated eye alignment - the side of the jaw bone and the cavity below the cheek bone. Both are covered with varying thickness of skin and tissue. When placed onto a correctly shaped comb these two points create a very stable platform to give consistent eye / rib alignment on a stationary and moving gun.

The contact of the jaw bone is pretty consistent by just bringing the gun into the face to look down the barrel. The big variable is the final position of the cheek bone in relation to the top of the comb.

To ensure repeatedly accurate eye / rib alignment the contact point of the cheek bone needs to be consistently in the same place.

If the cheek bone is not in contact with the comb it will cause the shot to go high. This can be adjusted for by altering the height of the comb. The big problem however is that because the cheek bone is not in firm contact with the top of the comb the face is allowed to 'roll' over or away from the comb when the gun is moved onto a variety of targets. This results in the eye being 'off centre' to the rib and the shot is placed to the side of the target.

If you do not have both points of alignment, you cannot guarantee to be looking down the centre of the rib each time you take a shot.
