Overview
The OTs-22 Buk (Beech) is a Russian compact submachine gun developed by designer Vladimir Zlobin at the Tula Arms Plant in the 1990s. Chambered in 9x19mm, including the high-pressure 7N21 armor-piercing loading, it is a blowback-operated, select-fire weapon built largely from stamped parts to reduce cost. Designed as a lightweight, concealable weapon offering close-quarters firepower, it shares ergonomics with the earlier PP-93. It remained a prototype and did not enter widespread service.

Notes
Sources commonly attribute the OTs-22 to 9x19mm rather than 9x18mm Makarov; it was developed for the high-pressure 9x19mm 7N21 round. Many specifications remain unpublished. Length cited as approximately 460 mm with stock extended and 250 mm folded.
Background
Named after the beech tree, the OTs-22 Buk was one of several compact Tula submachine guns developed in the chaotic 1990s arms-design boom, built around Russia's potent 7N21 9x19mm armor-piercing round to defeat body armor at close range.
