The Zastava M70 A, an early Yugoslavian AK variant, features a unique factory bolt hold-open mechanism requiring a specially modified receiver and magazines. This system allows the bolt to lock back on an empty chamber, facilitating faster reloads compared to standard AKs. While innovative, the complexity likely led to its discontinuation in favor of simpler designs.

Quick Summary

The Zastava M70 A features a rare factory internal bolt hold open mechanism. This system requires a modified receiver and magazines, allowing the bolt to lock back on the last round fired. The bolt remains open even after magazine removal, facilitating faster reloads, though the complexity likely led to its discontinuation.

Frequently Asked Questions

What is unique about the Zastava M70 A's bolt catch?

The Zastava M70 A features a factory-installed internal bolt hold open mechanism. This system requires a specially modified receiver and magazines to lock the bolt to the rear on the last round fired, a feature not commonly found on standard AK-pattern rifles.

How does the Zastava M70 A's bolt hold open mechanism work?

The mechanism uses a screw on the receiver and a modified magazine follower. When the last round is fired, the follower pushes up on the bolt catch, locking the bolt back. This hold open state persists even after the magazine is removed.

Why was the Zastava M70 A's bolt hold open feature likely discontinued?

The complexity of implementing the internal bolt hold open system, requiring specific receiver modifications and specially designed magazines, likely made it less cost-effective for mass production compared to simpler AK designs.
