AC13

AC13, also known as AC-13, is a type of ammunition used in firearms. It is a 13mm (0.512 in) diameter cartridge designed for use in submachine guns and other small arms. The AC13 was developed in the late 1960s by the Austrian company Steyr Mannlicher, and it was intended to replace the older 9x19mm Parabellum cartridge in submachine guns.

The AC13 cartridge is known for its high velocity and flat trajectory, which makes it suitable for close-quarters combat. It is also relatively easy to produce and maintain, which has contributed to its popularity among military and law enforcement agencies. The AC13 has been used in various firearms, including the Steyr AUG submachine gun and the Heckler & Koch MP5 submachine gun.

Despite its advantages, the AC13 has also faced criticism due to its relatively low stopping power compared to other cartridges of similar size. This has led to debates about its effectiveness in real-world scenarios. Additionally, the AC13 has been subject to export restrictions due to its potential use in military conflicts.

In summary, AC13 is a 13mm cartridge designed for submachine guns, known for its high velocity and flat trajectory. It has been used in various firearms and has been subject to debates about its effectiveness and export restrictions.
