Frequently Asked Questions

How did the Zastava M90 perform after being exposed to extreme winter conditions for 24 hours?

Did snow and ice affect the Zastava M90's functionality during the test?

Yes, snow and ice did get into the rifle's action, particularly around the bolt hold-open. However, this ingress did not prevent the rifle from functioning. The selector switch was also initially affected by ice but remained operable.

What was the condition of the Zastava M90's internal components after the winter test?

Internal components, including the bolt, bolt carrier, and trunnion, were in excellent condition. There was no visible deformation or excessive wear, indicating robust construction and durability even after prolonged exposure to harsh elements.

Are there any suggested improvements for the Zastava M90 based on this winter test?

The reviewer suggested that Zastava could consider offering an option to close the gap on the bolt hold-open mechanism. This would further prevent elements like snow and ice from entering the action, although it did not cause a failure in this specific test.
