Bipod
The bipod carries the barrel clamp, shock absorbers, damper rings, traversing, elevating, and cross leveling gears, and the bipod legs with spikes and cross struts.
The buffer springs are made of stainless steel, the damper rings of rubber. All gears are made of stainless steel and protected against water and dust.
Barrel and Breech Cap
The barrel is made of high-strength ESR special steel. It is forged, heat-treated, and machined to close tolerances. The forged breech plug is screwed into the barrel. A specially developed sealing ring guarantees gas-tightness. The firing mechanism can be switched from fixed to triggered firing. A safety lever is provided on the breech to avoid inadvertent firing. The breech ball fits into a socket in the center of the base plate, where it is fixed by a bayonet nut.

INA
Base Plate
Designed for the highest stability on all kinds of terrain and ground, it is made of welded steel and has six ribs and vents to ensure the desired result.
Sighting System
The A06 Mortar Sight is mechanical aiming device a was developed for indirect aiming of mortar in azimuth and elevation with precise elevation and azimuth adjustment by worm gear. The optic has a magnification of 2.6x and a field of view of 9 °; a crosshair reticle and its dovetail mounting is according to NATO standard. The complete telescope, with 2.6x magnification, can be tilted +/- 25 ° and rolled axially 90 °, ensuring convenient operation, particularly with different types of mortars. For night operations, the A06 is equipped with an LED electrical illumination system powered by two standard batteries 1.5 V (type AA), providing illumination of the scales, bubbles, and reticle.s the operator can adjust the mortar elevation according to range estimations or range measurements without additional ballistic calculations in the field. All viles and bubbles illuminated by LED´s enable the user to operate 24 hours, powered by two AA batteries directly on the sight.
