Raising cheek on a rifle

Hunter456

Dose raising the cheek piece on a rifle stock change POI.

No .All it should do is move your head and eye to be more in line with the scope.?

If you are not looking directly through the center of the scope you could have a differing poi due to parallax.
That is why its always best to adjust the comb and try shoot the rifle, in the same manner, every time, with your head in the same place etc..

As juice said it can but its more down to parallax than your cheek position.

If your parallax is off then any deviation from your "zeroing position" will result in a shift in POI as the crosshairs will "move" with your head/eye movement.

In a scope with a properly set parallax no matter your eye/head position the crosshairs will remain fixed.

The simple check for parallax is to set the rifle up in a locked/fixed position where it is almost clamped. Do NOT touch the rifle or as little as possible and look down the scope. It doesn't matter if your head is not in its natural shooting position, you're only checking for movement. Move your head slightly and if the crosshairs move with your movement then there is a parallax issue.

Parallax can be adjusted or eliminated by adjusting the eye relief and focus as necessary to the point where you have clear sight picture, target picture and no movement of the crosshairs. It can be easy or it can take a little time to get exactly right, but the difference will be immediately noticeable with more consistent groupings, no loss/shift of zero, and if the rifle and ammo are good a reduction (won't say elimination) of flyers.

To get back to your original point, a cheek riser can aid in this. Again as Juice said you need to be looking directly down the centre line of the scope. Have you ever looked through the scope and you get black or blurred picture on the edges? This shows poor eye position/relief. The best way to check this is to once again have the rifle clamped and adopt your shooting position. Now move your head, NOT your eye, until you get clear sight picture. Don't worry about parallax at this point. Now have someone else measure the amount you come up off the stock and the distance from the scopes ocular lens your eye is and that is where you need your head to be each time.

You can buy a packet of foam rubber pieces in any craft shop or Dealz etc.
Each is 2 or 3 mm thick, and with a bit of masking tape you can build up layer upon layer on the top of the stock until the height is right for you.

Something like a Karsten cheek riser is a better option, aesthetically, and comes in two versions. Drill the stock and attach or "stick on".

I should have said "as a temporary measure to find the best height"
