TKB-517

The TKB-517 assault rifle was designed by Gherman A. Korobov. This rifle was similar externally to the AK-47 but based on the delayed blowback mechanism invented by Pál Király. It turned out to be more reliable and accurate, and easier to produce and maintain. Like the AK series, it was also manufactured with folding stocks, long heavier barrels with bipods forming light support weapons and even a belt-fed variant. Its rejection was because of a greater proficiency with the AK-47 among the Russian military.

Overview
The TKB-517 is externally similar to the AK-47 and field-strips similarly, but instead it uses Lever-Delayed Blowback for its operation, slightly reducing recoil and making it more controllable. The receiver is made from pressed steel with laminated wood stock, grip and handguards.
