In order to ensure that forces acting on a breech drive when unlocking the breech and pulling out a cartridge case are reduced or even eliminated, a breech of a weapon system is proposed which is formed at least by one breech carrier and one breech head and the breech carrier supports the breech head. The breech carrier and the breech head can be mechanically separated from one another. This separability is achieved in that a control case which has at least one control cam is inserted in the breech carrier. In addition, the breech head has a control bolt which engages in the control cam of the control case and can be guided in it. This measure ensures that the forces acting upon the recoil of the weapon cannot act on the breech drive.

A small lightweight weapon system for integration into an unmanned aerial vehicle comprises a weapon operating group which utilizes blowback operation to fire a full-powered centerfire rifle ammunition. An operating rod of the weapon operating group has an axis of translation offset from the longitudinal axis of the barrel thereby creating a moment couple on the system. A motor assembly controls the operation of the weapon operating group. Through a gear train, actuation of the motor assembly lifts a sear against a return torsion spring, which holds the operating group back when not firing. The gear train comprises a one way flywheel disconnect to increase the torque of the direct current motor and overcome the force of the torsion spring. Intelligent motor commutation and burst control are achieved through an encoder and software package.

A weapon system having a breechblock, wherein the breechblock can be mechanically connected to a drive of the weapon system. The weapon system comprises means which are designed in such a way that a mechanical separation occurs between the breechblock and the breechblock drive with the recoil of the recoiling masses of the weapon system. With the forward motion of the recoiling masses, the mechanical connection between the breechblock drive and the breechblock is re-formed.

A breechblock for a weapon system having a recoilable barrel and having a breechblock carrier and a rotatable breechblock head. The breechblock head is carried by the breechblock carrier. The breechblock carrier has a control cam that is divided into a number of, preferably at least four, cam sections. The actual weapon function and the unlocking of the breechblock or of the breechblock head are combined in this control cam. The breechblock head comprises a control pin, which engages in the control cam and can be guided therein. Attached to the breechblock carrier are two blocking slides, which keep the breechblock head in one of two different positions, in which positions the breechblock head can enter or leave the locking portion of the barrel, namely, a forward position in the course of the actual functioning of the weapon and a rear position during the advancement of the returning masses.

Firearm bolt assemblies and firearms including the same are described. In embodiments the firearm bolt assemblies are configured to localize compressive forces applied during a transition from an initial position to a firing position to a first cam system on one side of the firearm bolt assembly, and to localize compressive forces applied during a transition from the firing position to the initial position to a second cam system another side of the firearm bolt assembly. Localizing the forces in that manner enables the use of a first cam system that is relatively robust compared to the second cam system.
