Duration: 13:23

This guide details the installation and testing of the Agency Arms 417 compensator on a custom Glock 19 build, as demonstrated by a firearms instructor. It covers securing the compensator, selecting appropriate recoil springs, and the importance of optics for compensating bullet drop. The guide emphasizes testing for cycling reliability with standard ammunition and notes the specific generation compatibility challenges.

Quick Summary

The Agency Arms 417 compensator offers unique features like integrated front sight mounting but suffers from generation-specific compatibility. It requires a workaround for cross-generation use and, when properly tuned with an 18lb recoil spring, ensures reliable cycling with standard ammunition. A red dot sight is recommended to compensate for the bullet drop induced by the compensator.

Frequently Asked Questions

What are the key features of the Agency Arms 417 compensator?

The Agency Arms 417 compensator features a unique design allowing direct mounting of a front sight, aiding in shot tracking. It's available in single and dual-port configurations and secures via 45-degree set screws.

How does the Agency Arms 417 compensator affect pistol reliability?

When properly installed with an appropriate recoil spring (around 18 lbs for Glock 19/17), the 417 compensator demonstrated reliable cycling with standard range ammunition and locked open on the last round during testing.

What is the main drawback of the Agency Arms 417 compensator?

The primary criticism is its lack of modularity. The compensator is proprietary to either Gen 3 or Gen 4 Glock models, requiring a specific workaround with a reducing ring for cross-generation use.

Why is a red dot sight recommended with a compensator?

Compensators can cause a noticeable bullet drop (1-2 inches) at target distances. A red dot sight allows for quick and easy elevation adjustments to compensate for this shift in the point of impact.
