Frequently Asked Questions

What is the Jatimatic submachine gun?

The Jatimatic is a Finnish 9mm submachine gun designed by Jali Timari in the late 1970s and produced from 1983. It was intended as a compact PDW for specialized forces and features a distinctive angled bolt design for recoil control.

What makes the Jatimatic's bolt design unique?

The Jatimatic's most notable feature is its 'wonky' angled bolt, which travels at a 7-degree upward angle relative to the barrel. This design aims to counteract muzzle rise by shifting the center of gravity and using the bolt's recoil force to push the muzzle downward.

What materials were used in the Jatimatic's construction?

The Jatimatic features a stamped steel construction made from two welded halves. It also incorporates a glass-reinforced polymer lower receiver and trigger housing, which was a modern material choice for firearms in the early 1980s.

Did the Jatimatic see widespread military adoption?

No, despite its innovative design, the Jatimatic was rejected by the Finnish Defense Forces and never achieved widespread adoption. It gained a cult following through its appearances in popular culture, particularly in films.
