    I tried shouldering a high rib trap gun (Browning Citori CXT) last weekend, and it really seemed to fit me well. I have always struggled with keeping my face down on the stock sufficiently to actually be looking along the rib to the front bead. I tend to keep my head up slightly, which makes me "look down onto" the rib somewhat. The high rib and high comb on the CXT seems to compensate for my lousy form.

    Question: What difference does the high rib make in where the gun patterns? Does it create any alignment problems versus a regular rib? Are there any distinct advantages to one, so that it should be worthy of serious consideration?

    The rib is higher in the back to make the gun shoot high.

    Imho.....the high rib on some trapguns are to simply dissipate heat waves that can distort your view of the target on a hot day.

    The ADJUSTABLE rib can be adjusted to change the point of impact.

    Not all high ribs are adjustable.

    Just for fun, try mounting the gun higher on your shoulder. That can keep your head a bit more upright and natural position which might keep you from raising your head.

    This pad can be adjusted to make most all shotgun shoot high and it locks in the position of the gun each time.
    Trap guns are designed to shoot about 9" high. This compensates for the rising clay target. https://morganrecoilpad.com The comb is higher, help keep the face on the stock. (Wood to Wood) :D

    Adjustable for skeet.

    Gun down ? Switch to the flat pad.

    20180809_080708.jpg My trap gun has a high comb. Now its adjustable.

    Pad spacer will reduce recoil. May have to cut stock, if current gun doesnt have a 1" thick pad from the factory.

    The high rib, as my friend Farmer has said, is mainly to dissipate heat waves. I made a high rib barrel for my late brother's 870TC as I could not get down enough on the stock to see the sight picture I wanted. (sights are for alignment, you forget them when you call for the bird as you are focusing on where the bird should appear.). A rib, no matter how high, if parallel to the original rib or barrel should not impact poi. An adjustable rib can be used to change poi. Raise the rear or lower the front and you raise poi. Raise the front or lower the rear and the poi lowers. The most common reason for a high rib is to allow a more upright stance with less canting of your head. Combined with an adjustable comb and adjustable buttplate you can fit the gun to you. (I don't commonly worry about fit as I've been shooting the same 870TB since 1975 and believe my body has fit itself to the gun after 43 years and a couple hundred thousand shots fired).

    While they do dissapate heat better, the reason is to put a higher percentage of the shot load above the point of aim. This is usually expressed as a percentage, i. e., 60/40 or 70/30. A field rib is 50/50, which is why you have to 'cover the bird', fire and follow through (on straight aways and slight angles; obviously you have to lead more on higher angles.) With a 70/30 barrel, you put the bead on the target's bottom, and fire. (again, with more lead on harder angles) In Trap, the bird is rising, and you should shoot it while it still is rising. (Unless you are shooting an Aniie Oakley, and you are shooter #4 or 5...) Generally a fixed high rib of 70/30 is fine for Trap, Sporting Clays shooters usually prefer 60/40, or even 50/50, as do Skeet shooters. Adjustable ribs can go from 50/50 to as high as 90/10. (The main use for that would be a shooter that is on the 27 yard line.)

    A Morgan pad as 243winxb suggests will do this, without the resulting increase in recoil impulse.

    Or adding an adjustable comb...

    Well, it can mess with your live game shooting, but fairly easy to learn the difference in shooting two or even three different rib types. The advantage for Trap, as Colt Python Elite pointed out, is that you don't have to cover the bird with your barrel, as with a field rib; it usually improves most shooter's scores.

    Sorry to sound naive, but what guns have "adjustable ribs"? And, just how do you adjust them?

    Any gun can have one:

    http://adjustarib.com/

    Usually higher priced names like Perazzi, Caesar Guerini and Kreighoff have them on their Trap guns.

    They are usually adjusted by setting some set screws on the rib, back and front, sometimes middle, too. You shoot at a pattern board to determine where the center of the shot pattern is hitting, and adjust the rib up or down until it is hitting where you want it to.

    As you can see from the demo pics, the types are just to match the factory rib; they are all shown mounted on an 11-87 barrel, they are all a standard width.
