A Stutzen is a rifle where the fore-end extends to the muzzle. This is primarily achieved through a longer fore-end; on the other hand, Stutzen traditionally also often have shorter muzzles than "half-stocked" rifles.
With rifles that have short barrels, and thus many Stutzen, there is a risk that the propellant charge of the cartridges does not burn completely before the projectile leaves the barrel. If this is the case, the projectiles do not reach the velocity for which they were designed. Additionally, the muzzle blast, muzzle flash, and recoil may be stronger under certain circumstances.
The greatest advantage of a Stutzen lies in its beauty; furthermore, the rifle can be rested all the way to the muzzle. Due to the recoil, it is not possible to rest the barrel directly on half-stocked weapons and thus take a precise shot. A significant disadvantage of a Stutzen is that a suppressor cannot be screwed on.
A Stutzen is to be distinguished from a mountain Stutzen.
