A modular weapon system of a preloaded recoilless gun including a barrel provided with a shell, a propellant charge and a countermass. The weapon system is configured in two parts including a first part of the barrel and a second part of the barrel. The first part of the barrel includes the shell and the second part of the barrel includes the propellant charge and countermass. A releasable locking device interconnects the second part of the barrel with the first part of the barrel.

Weapon system

An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container that can be opened at both ends. The invention aims to bring about a symmetrical opening with favorable recoil in a better way than in previous constructions. This is achieved by the countermass including elements that can bind and retain the liquid symmetrically in a desired geometry over the cross section of the barrel and the cross section of any following expansion part.

Arrangement for weapon

An arrangement for a weapon including a countermass for reducing the pressure around the weapon. The countermass is enclosed in a countermass container with an openable cover provided with break indications. The arrangement brings about a symmetrical opening operation with favorable recoil in a better way than in previous constructions. This is achieved by the introduction of a guiding folding support arranged adjacent to the openable cover on the inside of the cover relative to the countermass container.

The invention relates to a holder device configured for fastening to a substantially cylindrical body, such as a gun barrel, for the support of equipment such as a sight. The holder device comprises at least two holder elements, one holder element being configured for secure fixing to the cylindrical body and the other one being arranged such that it is movably coupled to the first-named holder element. According to the invention, the holder elements are arranged such that they are rotatable in relation to each other about a common axis between a first position, the transport position, and a second position, the activated position, and one of the holder elements is axially displaceable along the common axis from a position of equilibrium defined by a spring arrangement. The holder device reduces the transmission of axial recoil motions between the holder elements.
