Stab Primer

A stab primer, also known as a starting primer or a percussion primer, is a small explosive device used to initiate the ignition of a larger explosive charge. It is typically used in firearms, artillery, and other military applications.

The stab primer consists of a small metal cup filled with a sensitive explosive compound, such as lead styphnate or mercury fulminate. When struck by a firing pin or a similar mechanism, the stab primer detonates, creating a small flame or spark that ignites the main propellant charge.

Stab primers are designed to be reliable and consistent in their ignition properties, ensuring that the main explosive charge is ignited consistently and efficiently. They are an essential component in the functioning of firearms and other explosive devices, providing the initial ignition necessary for the controlled release of energy.

It is important to handle stab primers with care, as they are highly sensitive and can be dangerous if mishandled or improperly stored. They should only be used by trained professionals in accordance with proper safety protocols and regulations.

Overall, stab primers play a crucial role in the safe and effective operation of firearms and other explosive devices, ensuring reliable ignition and controlled release of energy.
