Duration: 2:00

This video details extensive testing of a Gen 6 Glock 17, focusing on optic zero retention under demanding conditions. The presenter conducted 3,000+ rounds over three days, incorporating one-handed reloads and deliberate optic manipulation. The results indicate superior zero stability compared to MOS systems, even after a dropped firearm incident.

Quick Summary

The Gen 6 Glock 17's optic mounting solution demonstrated superior zero retention after over 3,000 rounds of testing, including demanding one-handed reloads and a firearm drop. This performance significantly surpasses that of the Glock MOS system.

Frequently Asked Questions

How many rounds were fired during the Gen 6 Glock 17 optic test?

The presenter fired over 3,000 rounds during the testing period for the Gen 6 Glock 17. This high volume was spread across three days to ensure thorough evaluation of the firearm and its optic's zero retention.

What specific drills were performed to test optic zero retention on the Glock 17 Gen 6?

The testing included extensive one-handed shooting, deliberate slide lock reloads where the slide was charged off the presenter's belt, and both right-handed and left-handed manipulations to simulate real-world stress.

Did the optic on the Gen 6 Glock 17 maintain zero after the firearm was dropped?

Yes, during a left-handed reload, the firearm was accidentally dropped. Despite the impact, subsequent zero checks confirmed that the optic had maintained its zero without any shift or loss.

How does the tested optic mounting solution compare to the Glock MOS system?

The presenter concluded that the optic mounting solution used on the Gen 6 Glock 17 is far superior to the standard Glock MOS system, citing its exceptional zero retention and reliability under demanding conditions.
