EOTech 553 Holographic Sight (SU-231/PEQ) Review (HD)

Published on February 2, 2014
Duration: 6:28

This review of the EOTech 553 holographic sight, also known as the SU-231/PEQ, highlights its selection for the SO2 program by the US military. The optic features a 65 MOA ring with a 1 MOA dot reticle, parallax-free operation, and is powered by two CR123 batteries. While generally reliable on 5.56/.223 platforms, potential battery issues under heavy recoil (like on a 7.62 SCAR Heavy) were noted, leading to design changes in newer models. The 553 includes integrated ARMS levers for 1913 rail mounting and offers 1 MOA adjustment increments.

Quick Summary

The EOTech 553 holographic sight (SU-231/PEQ) was a key optic for the US military's SO2 program, featuring a 65 MOA ring with a 1 MOA dot and parallax-free operation. While reliable on 5.56/.223 platforms, heavy recoil can cause battery issues due to in-line battery orientation, a design addressed in newer models.

Frequently Asked Questions

What is the EOTech 553 holographic sight known for in military applications?

The EOTech 553, also designated SU-231/PEQ, gained prominence as the optic of choice for the US military's SO2 program, leading to its widespread deployment with special operations forces.

What are the key features of the EOTech 553 reticle and its performance?

The EOTech 553 features a 65 MOA ring surrounding a 1 MOA dot. It is designed to be parallax-free, ensuring the aiming point remains consistent regardless of the shooter's head position.

What potential issues have been noted with the EOTech 553, especially concerning recoil?

Under heavy recoil, such as from a 7.62 caliber weapon like the SCAR Heavy, battery failures have been reported due to the batteries' in-line orientation. Newer EOTech models address this by orienting batteries perpendicularly.

How does the EOTech 553 mount to a firearm, and what are its adjustment capabilities?

The 553 integrates ARMS levers for quick attachment to any 1913 Picatinny rail. It offers windage and elevation adjustments in 0.5 MOA increments and claims a 1 MOA return to zero.
