The Monte Carlo comb came to rifles via shotgun stocks. It
rises well above the ordinary comb line of the stock at the
butt and tapers downward toward the point of the comb. This
raised portion of the stock lifts the face of the shooter and his
or her line of sight well above the standard elevation provided
by the classic style. However, the same amount of drop is
maintained at the buttstock. A shooter with a long neck who
often has trouble getting his or her face down far enough on
the comb of the regular stock benefits from the Monte Carlo

The tendency of a firearm when fired to move backwards, and a little upwards as a reaction to the force of the projectile moving down the barrel.
As Newton says, to every action there is always an equal and opposite reaction. The mass of the firearm provides some inertia to counteract the momentum of recoil.
What remains is absorbed by at the shoulder or the hand. The heavier the gun, the less the recoil. The more powerful the cartridge, the more the recoil.

with one eye open and moving the head to alternately see the sight and then at the target, or using one
eye to partially see the sight and target at the same time.
The point of a projectile.
