Duration: 16:50

This video provides an in-depth, 2500-round post-test analysis of the ODS 1775, focusing on reliability issues encountered, particularly with suppressed fire and specific magazine types. The presenter details findings on wear patterns, component integrity, and the impact of aftermarket parts like the ALG trigger, concluding with a headspace check.

Quick Summary

After 2500 rounds, the ODS 1775 experienced live round ejection issues primarily when suppressed, linked exclusively to Magpul AK-47 magazines. Testing with Beryl, Pro Mag, Tapco, and Bakelite magazines showed no such problems, suggesting magazine compatibility is key.

Frequently Asked Questions

What were the primary reliability issues encountered with the ODS 1775 after 2500 rounds?

The main issue was live rounds being ejected during the loading sequence, particularly when the firearm was suppressed. This was found to be exclusively linked to Magpul AK-47 magazines.

How did suppressor use affect the ODS 1775's reliability?

Suppressor use appeared to increase carrier speed, which, in conjunction with specific magazines, contributed to malfunctions like the ejection of live rounds. The gun ran without issues when unsuppressed.

Which magazines performed reliably with the ODS 1775 during testing?

While Magpul magazines caused ejection issues, Beryl, Pro Mag, Tapco, and Bakelite magazines all performed flawlessly throughout the testing period.

What were the findings regarding the ALG trigger components in the ODS 1775?

The ALG trigger parts are significantly harder than standard Combloc specifications. While they showed minimal wear, this extreme hardness is a concern for potential long-term damage to other components, like the bolt carrier.
