The TKB-059 is an example of a bullpup firearm.

Bullpup is a firearm configuration in which the action (or mechanism) and magazine are located behind the trigger. This increases the barrel length relative to the overall weapon length, permitting shorter weapons for the same barrel length, saving weight and increasing maneuverability. It alternatively allows for longer barrels on weapons of the same length, improving trajectory and effective range.

The concept was first used in bolt-action rifles such as the Thorneycroft carbine of 1901, and is known to have been applied to semi-automatic firearms in 1918 (6.5 mm French Faucon-Meunier semi-automatic rifle developed by Lt. Col. Armand-Frédéric Faucon), then in 1936 a bullpup pistol was patented by the Frenchman Henri Delacre. A 7.62 mm caliber experimental assault rifle was developed by Korovin in the Soviet Union in 1945. The United Kingdom had been considering the idea of a bullpup service rifle since 1944. Two designs, the EM-1 and the EM-2 were developed by the British as a replacement for separate pistol, submachine gun and rifle. The choice of bullpup design was a necessity to keep the accuracy up while keeping overall length down. The EM-2 was adopted by the UK in 1951 as the world's first (limited) service bullpup rifle but was promptly displaced by the adoption of the 7.62 x 51 mm NATO cartridge.
