SIG SAUER SWISS ARMS SG552 - Manual (Page 16)

3.12. Rifle Grenades (Bullet trap type)
3.12.1. General
The rifle grenades are intended to be launched in flat trajec-
tory. Standard, live ammunition is used for launching,
whereby the weapon cycles automatically. (The bullet is
caught in the bullet trap integrated in the grenade)
3.12.2. Handling
Acting on orders, or his own initiative in situations of
danger, the trooper prepares his weaon for grenade
launching.
Loading procedure:
• Load model SG 552 LB rifle with standard,
hardball ammunition
• Place safety lever of model SG 552 LB on “S“.
• Mount rifle grenade: it must be possible to twist on the
grenade up to the stop without encountering significant
resistance.
3.12.3. Aiming
At a range of 75 m, aim over the upper edge of the rifle
grenade and the upper rim of the foresight tunnel. At lon-
ger ranges, cover the target with the body of the grenade.
Consequently, first obtain the height of the target by
approaching it from the side. Then move the rifle sideways,
without changing the inclination of the barrel, until the
target is covered.
Range 75 m: Point of aim = average point of impact
Launching positions: The grenade launching can be done
from the standing, kneeling and prone positions. The rifle
butt should be held as tightly as possible under the armpit
of the firing arm; the other hand grasps the handguard
firmly. The safety lever is on position “1”. Firing from the
shoulder is also possible. However, the trooper must take
cover before the grenade detonates upon impact.
