The TKB-517 (Russian: ТКБ-517) is an assault rifle designed by German Aleksandrovich Korobov. This rifle was externally similar to the AK-47, but based on the lever-delayed blowback mechanism invented by John Pedersen and refined by Pál Király. It turned out to be more reliable and accurate, and easier to produce and maintain.[1] Like the AK series, it was also manufactured with folding stocks, longer, 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.

Design and features

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.
