<P> The grip area is held by the shooter's trigger hand during firing, and is the part of the butt that connects with the fore - end . The back part of the grip is called the tang . Many grips have roughened textures or even finger grooves engraved into the sides to increase the firmness of the shooter's hold . Some grips have a thumb rest (or thumb groove) carved near the tang to give a more ergonomic hold for the trigger finger . </P> <P> The grip varies widely in styles . A straight grip stock (A) proceeds smoothly from toe to the trigger, giving a nearly horizontal holding angle for the trigger hand, while a full pistol grip stock (E) contains a separate stand - out grip piece, providing a nearly vertical angle for the trigger hand for maximal ergonomics, and is commonly found on modern military rifles such as the ubiquitous AK - 47 and M16 families of assault rifles . In between the two extremes, the semi-grip stock (B) is perhaps the most common sporting rifle stock, with a steeper angle cut into the stock to provide a more diagonal angle for the trigger hand . Modern target - style stocks have generally moved towards a fuller, more vertical grip, though built into the stock rather than made as a separate piece . Anschütz grip stocks (C), for example, use a nearly vertical grip, and many thumbhole grip stocks (D) are similar to pistol grips in shape . </P> <P> The comb is another area of wide variation . Since the comb must support the shooter's cheek at a height that steadily aligns the aiming eye with the weapon's sights, higher sights such as telescopic sights require higher combs . </P> <P> The simplest form is a straight comb (A), which is the default form seen in all traditional rifles with iron sights . The Monte Carlo comb (B) is commonly found on stocks designed for use with scopes, and features an elevated comb to lift the cheek higher, while keeping the heel of the stock low . If the elevated comb is of a rounded dome shape, it is often called a hogback comb . A cheekpiece (C) is a raised section on the side of the stock, which provides a more comformed support for the shooter's cheek . There is some confusion between these terms, as the features are often combined, with the raised rollover cheekpiece (D) extending to the top of the stock to form essentially a high Monte Carlo comb . </P>
