This guide details how to assess parallax error in red dot sights, a critical factor for accuracy. The video highlights the Trijicon SRS's significant parallax issues compared to competitors like the Aimpoint T2 and Eotech EXPS3. It emphasizes that even expensive optics can have flaws, underscoring the importance of empirical testing.

Quick Summary

The Trijicon SRS (Sealed Reflex Sight) is a discontinued red dot sight known for its severe parallax error, making the point of aim shift considerably with head movement. It is also notably heavy at 13.8 oz with its QD mount and suffers from internal reflections and poor night vision compatibility, despite having a solar cell backup.

Frequently Asked Questions

What are the main drawbacks of the Trijicon SRS red dot sight?

The Trijicon SRS suffers from severe parallax error, significant weight (13.8 oz with QD mount), internal reflections, and poor performance with night vision and magnifiers. It was also quickly discontinued after its release.

How does the Trijicon SRS compare to the Trijicon MRO in terms of parallax?

The Trijicon SRS exhibits much worse parallax error than the Trijicon MRO. Head position shifts can cause the SRS's point of aim to move several feet at 100 yards, a much more pronounced issue than seen with the MRO.

What is the battery life and power source for the Trijicon SRS?

The Trijicon SRS uses a single AA battery (lithium or alkaline) with a claimed life of 3 years at setting 7 of 10. It also features a top-mounted solar cell, but requires the battery to be installed and functional for operation.

Why was the Trijicon SRS discontinued?

The Trijicon SRS was discontinued likely due to its significant performance flaws, particularly its severe parallax error and heavy weight, which made it less competitive compared to other optics available at the time, including Trijicon's own MRO.
