The tool driving rod (6) drives a tool (7) and a firing block (5) to move.

Said first sliding breech-block (19) is interchanged for a second sliding breech-block (21) when firing caseless ammunition.

The tool driving rod (6) drives a tool (7) and a firing block (5) to move.

A stopped shot will only do damage to the first block.

The cartridge holder (1) is pivotally provided with a safety block (8) for preventing firing for the second time.

Next, the shooter pushes the slide forward, which pushes the block and firing pin into the firing position against the cartridge.

GIOVE-B Launch Campaign (3)Mating of Block E on Soyuz Packet

Aim for the best shots in this nice and polished physics block shooting game.

At the Téting, the slots in the firing chamber of Block 3 are beginning to be seriously damaged.

The breech assembly (10) further includes a crank means, which includes a guide means (26) for rotating the tilting block assembly (14) from the PGC firing orientation to the PGC loading/removal orientation.

▲ Increased speed of fully-charged shots by roughly 50% without changing shot distance.

A weapons training range provides a simulated weapons use scenario including return fire.

The TIR structures may be a TIR prism having its hypotenuse as a TIR surface.

The striker-trigger mechanism consists of a striker mechanism, a trigger mechanism and a fire-selecting mechanism integrated via a rear block (30).

The combination-type amplifier with multiple power sources according to the present invention includes a linear amplifying unit, a first sensing unit, a second sensing unit, a comparing unit, a gate driving unit, a switch unit, and a filter unit.
