MRPOWER's "wild stab" is right on. Only with extremely inadequate pitch will the pattern have a small chance of lowering with the use of a positive, tapered spacer (thick end at the top.)

Given a number of assumptions, lowering the height of the eye relative to the height of the rib is what lowers the pattern's point of impact.

Using a tapered spacer to make the recoil pad or butt make more even contact (top to bottom) with the shoulder is the purpose of tapered spacers.

Thanks for the replies.

I was looking for an easy way out before I either lowered the comb myself or pay someone hard earned money to do it.

I'm just trying to get it to shoot flatter.

Rather than lowering the comb, you could raise the rib. This can be done with what is known as an "add-on" rib. These ribs area available in either delrin (a space-age plastic) or aluminum.
The delrin ribs are available for less than $100.

Both types attach to the existing rib by means of an entirely satisfactory two-sided tape and come in a number of heights. Trial and error using balsa strips will determine the height you need.

Add-on ribs have been used by trap shooters for years.

Bob white, Please tell me again why you think you need to lower the comb. I am really surprised that someone needs to lower a comb; most need to raise it. What are you shooting, and how is it set up? My gun is set up so I am a quarter inch above the rib, and it is great. I do not raise my head to see targets and when I am shooting the way I know I should, I center the targets in the pattern. I find it hard to imagine that you really need to lower a comb. Tell me what you are shooting and how you have the gun set up, please. Floyd in Vienna

Are the add-on rib extensions suitable for a field gun?

Can you list a couple of suppliers? I was sent to trapshooters.com to find them, but all I found was pages of links. I looked until I had a headache. I Googled until I was worn out, too, and only found one supplier (in Australia!).

Thanks for any help,

I purchased one of the Yildiz MX clay guns. From th factory it comes with a Monte Carlo stock, and it is pretty high. It is completely stock, haven't done a thing to it.

Patterned and it was roughly 70/30. I want it to be 55/45 or as flat as I can get it. Hence the questions on lowering the POI.

I like the suggestion above about raising the rib height. I made a rib today that raises the front bead about 1/4 of inch. I'm gonna try to run out to the range tomorrow and give it a try.

I believe it was Moneymaker who sells aluminum add-on ribs but I don't remember who sells delrin ribs. I'll put a thread on ts.com and let you know in a day or so.

I forgot to answer the question if add-on ribs would work on field guns. Than answer is yes, providing the gun already has a rib. Add-on ribs are not designed to attached to plain barrels.
