    This may seem like a stupid question, but as I come from Australia, all trap guns are O/U (you get two shots per clay). As you can imagine, with two shots, all competitions end in shoot offs that can last for hours and get very boring.

    What's the functional difference between the unsingle and the top single? Wouldn't you always want the single in the top, so you have a straighter line between the stock and cheek (you know what I mean)?

    The top single is basically in the position of the upper barrel of an O/U. The Unsingle is, therefore, in the position of the lower barrel of an O/U. Actually, the lower barrel or Unsingle is more in direct line with recoil to the shoulder and that's one of the alleged arguments in favor of it; less propensity to have muzzle rise since the recoil is more straight back. The other alleged benefit is that with the lower barrel position and openness of the rib at the standard height you enjoy an earlier view of the bird leaving the house in trap. I've owned and shot both styles and never could see enough difference to warrant preferring one over the other for me.....Bob Dodd

    An unsingle creates less barrel rise during recoil, which is a primary benefit of unsingles. They also allow a better view of rising targets (for some shooters.)

    The position of the lower barrel, the only one there is with an unsingle gun, is more in line with the heel of the recoil pad than is the barrel of a top-single gun. This is what accounts for the reduced barrel-rise.

    The same is true for the bottom barrel of an over-under. It is the reason most people shoot the lower barrel first in two-shot games.

    The distance between the cheek and the barrel is not a factor in either sighting a gun or the resulting recoil. It is the distance of the comb and the rib that is important in that the "drop at the comb" must match the distance of the cheekbone below the pupil of the eye. It allows the eye to look along or slightly down-onto the rib to achieve the preferred point of impact.

    Not everyone can use an unsingle. Some shooters have difficulty with their "off" eye and the view of targets when it sees them through the high rib.

    Unsingle costs more than a Top Single.

    The greater distance between the rib and the barrel reduces the effects of heat waves off the barrel.
