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