Beretta 686 vs 692 : Internals

Published on May 9, 2020
Duration: 5:59

This video details the internal differences between the Beretta 686 and 690 shotguns, focusing on the action's front and rear. While the core trigger and sear mechanisms are similar, the 690 features a more modern, refined engineering approach, including a different forend iron design, a slimmer ejector profile, and a more robust quad-locking system at the rear. The safety catch mechanism also differs significantly, with the 690 employing a more secure rocker-based blocker.

Quick Summary

The Beretta 690 shotgun features a more modern and refined internal design compared to the 686. Key differences include a wider alloy forend iron, a slimmer ejector profile, Torx screws for easier maintenance, a stronger quad locking system, and a more secure direct mechanical block in its safety catch mechanism.

Frequently Asked Questions

What are the main internal similarities between the Beretta 686 and 690 shotguns?

Both the Beretta 686 and 690 shotguns share very similar core internal mechanisms. This includes the inertia rocker, the trigger system, the sear system, and the mainsprings. While there are minor geometric differences that prevent parts interchangeability, the fundamental operation of these key components remains largely the same.

How does the forend iron differ between the Beretta 686 and 690?

The Beretta 686 features a single-piece steel forend iron with kickers. In contrast, the Beretta 690 has an alloy forend iron that is significantly wider and shaped differently. The 690's design incorporates a swung forend mechanism to provide tension.

What is the key difference in the safety catch mechanism between the Beretta 686 and 690?

The Beretta 690's safety catch offers a more secure, direct mechanical block that slides over the trigger when engaged. The 686's safety catch lacks this direct block; instead, it uses a rocker within a pin to engage the blocker, which is considered a slightly less robust system.

Does the Beretta 690 have a stronger locking system than the 686?

Yes, the Beretta 690 features a quad locking system, utilizing four lugs for a more robust lock-up from the top lever down into the spindle. The 686, while still effective, employs a twin lug lock in comparison, making the 690's system generally considered stronger.
