A fire-control device for a small arm includes an inertial sensor unit for six degrees of freedom, a distance sensor for determining a distance to a target sighted via a sight, and a computation device for determining a target orientation of the small arm from the distance so as to be able to hit the target, the computation device being set up to detect a change in position of the small arm by way of the inertial sensor unit and to correct the target orientation using data from the inertial sensor unit.

A safety apparatus for a grenade launcher assembly which provides a dual-way ammunition feed, recognizes the direction automatically without the importance of which direction the user opens the handle in order to prevent the direction selector or movement from reversing and which does not permit opening to the other unselected side for the filling-off phase.

A barrel breech lock and mechanism for a projectile launcher chat uses a launcher body, a lower rail extending forward and under the launcher's barrel breech and a pivotally mounted latch plate. Extending downward extending from the latch plate is a front handgrip. Disposed between the lower rail and the latch plate and directly above the front handgrip is a locking mechanism that selectively blocks rotation of the proximal end of the latch plate. In two embodiments, the locking mechanism is a biased lateral push button or a biased sliding button. When the lock mechanism is activated, the proximal end of the latch plate may be rotated downward by a twisting force applied via the from handgrip. Disposed between the proximal end of the latch plate and the barrel breech is a second lock mechanism that includes a pin. The end of the pin engages a stop surface formed on the barrel breech when axially aligned in the breech void area. The first lock mechanism can be easily activated with the hand holding the from handgrip. Because the first and second lock mechanisms must be sequentially activated in order to open the barrel breech, the operation of the projective launcher is safer.

A grenade launcher, including: a barrel for launching a projectile at a real target and a sight coupled to the barrel, the sight including: a display that displays an aiming indicator and is configured to display a representative target representing the real target: a sensor configured to track motion of the barrel and accordingly the representative target is moved on the display; and wherein when the display of the representative target coincides with the aiming indicator, the launcher is aimed to launch the projectile to hit the real target.
