The sight assemblies, the trigger and trigger guard, and the safety are shown in Figures through The handguard assembly houses the rifle barrel Figure The quadrant sight assembly, which attaches to the left side of the rifle's carrying handle, enables the grenadier to adjust for elevation and windage Figure This assembly consists of the sight, mounting screw, sight latch, rear sight aperture, sight aperture arm, front sight post, and sight post arm Figure The clamp and the bracket assembly hold the quadrant sight on the rifle's carrying handle.
The mounting screw inserts through the right side of the clamp and into the bracket assembly. The sight arm mounts both the sight aperture arm which holds the rear sight aperture and the sight post arm which holds the front sight post. This procedure allows the sight to pivot on the range quadrant to the desired range setting.
Applying rearward pressure on the sight latch releases the quadrant sight arm so it can move along the range quadrant. Centering the number in the rear sight aperture selects the desired range. Releasing the sight latch locks the sight in position. The front sight post mounts on the sight post arm by means of a pivot bracket. To prevent damage to the sights, keep the bracket closed when the sights are not in use.
Use the sight post as follows to make minor adjustments in elevation when zeroing the launcher:. To move the impact of the projectile 2.

Two mounting screws permanently attach the sight base to the rifle handguard. When the sight is down or not in use, the base protects it from damage. The grenadier uses the sight mount, which is attached to the sight base, to raise or lower the sight.
Though the range is not marked on the sight in meters, the sight is graduated in meter increments from 50 to meters, which are marked with a "1" at meters and a "2" at meters. The screw attaches the sight to its mount. When the screw is loosened, the sight can be moved up or down to make minor adjustments in elevation during the zeroing procedure. The rim of a mm cartridge case is useful for turning the screw. Raising the sight increases the range; lowering the sight decreases the range.
The elevation scale consists of five lines spaced equally on the sight. The index line is to the left of the sight. Moving the sight one increment moves the impact of the projectile 10 meters in elevation at a range of meters. The knob on the left end of the windage screw is used to make minor deflection adjustments during the zeroing procedure. The scale has a zero line in its center and two lines spaced equally on each side of the zero line.
At a range of meters, turning the knob on the windage scale one increment to the left moves the impact of the projectile 1. The trigger guard protects the trigger A, Figure Depressing the rear portion of the trigger guard rotates it down and away from the magazine well of the rifle, which allows the weapon to be fired while the firer is wearing gloves or mittens B, Figure The safety is inside the trigger guard, just in front of the trigger.
