Abstract: The invention relates to a foldable grip for mounting on an elongate object, such as the barrel of a portable weapon. The grip comprises an elongate grip section and a hinge which connects the grip section to the elongate object. For effecting the movement between a folded-in position and a folded-out position, the hinge consists of an oblique pin to be affixed on the elongate object and of an oblique hole formed in the grip section and cooperating with the pin. During the movement of the grip section between the folded-in position and the folded-out position, the grip section turns through essentially 90 degrees around an axis in the longitudinal direction of the grip section.

Abstract: Training device for shooting with a weapon intended for use with live ammunition. The training device includes a sub-calibre barrel, which is attached inside a holder, which is capable of being locked in the barrel of the weapon. The sub-calibre barrel can be zeroed by means of four adjusting elements, of which two are spring-loaded and are in contact with the sub-calibre barrel whereas the other two are capable of radial displacement in relation to the sub-calibre barrel by individual operating rods running axially to the sub-calibre barrel.
