How To Set Up 4x Trijicon ACOG For Better Eye Relief (HD)

Published on July 8, 2017
Duration: 5:21

This video addresses the common challenge of short eye relief on 4x Trijicon ACOGs, typically around 1.5 inches. The presenter demonstrates a practical solution by reversing the mounting order of the optic and backup iron sights (BUIS). By mounting the ACOG further back, even over the charging handle, and placing the BUIS in front, shooters can achieve a more comfortable eye relief and better shooting ergonomics, despite a slightly reduced sight radius for the backup irons.

Quick Summary

Improve your Trijicon ACOG eye relief by reversing the mount order. Mount the ACOG further back on the rail, even over the charging handle, and place backup iron sights in front. This setup significantly enhances shooting ergonomics and comfort, despite a slightly reduced sight radius for the BUIS.

Frequently Asked Questions

What is the main problem with Trijicon ACOG scopes regarding eye relief?

The main issue with 4x Trijicon ACOG models like the TA31 is their very short eye relief, typically around 1.5 inches. This makes it difficult for many shooters to achieve a comfortable and consistent sight picture, especially when using different shooting positions or rifle stocks.

How can I improve eye relief on my Trijicon ACOG?

A common and effective method is to reverse the mounting order. Mount the ACOG further back on the rifle's Picatinny rail, potentially extending over the charging handle. Then, mount your backup iron sights (BUIS) in front of the ACOG.

Does moving the backup iron sights forward affect accuracy?

Yes, moving the BUIS forward shortens the sight radius. However, for backup purposes, the presenter argues that an 11-inch sight radius is still sufficient to accurately hit targets at 100 yards, making the trade-off worthwhile for improved primary optic ergonomics.

What are the benefits of adjusting ACOG mounting for better eye relief?

Adjusting the ACOG's position for better eye relief allows for a more comfortable head position and the ability to run the rifle stock further out. This results in improved shooting ergonomics and a more consistent full field of view, enhancing overall shooting performance.
