The EOTech Holographic Hybrid Sight package includes the EXPS3-4 red dot sight, as well at the G33.STs EOTech 3x magnifier. This combination of optics gives you a very modular and capable pack that can be adapted to work in a variety of situations.
Red Dot Sight
The heart of the EOTech HHS I Package is the EXPS 3-4 red dot sight. This optic offers a large viewing window, which facilitates both eyes open shooting. This optic utilizes, the EOTech -4 BDC reticle. This reticle features a 60 MOA quick target acquisition ring, along with four (4) 1 MOA red dot aiming points. The four (4) 1-MOA aiming points act as a bullet drop compensator, by giving you aiming references for multiple distances. The reticle is calibrated for a .223/5.56x45mm chambered rifle with a 14.5” barrel shooting a M855 62-grain load having a muzzle velocity of 2680 feet per second. When utilized with that rifle and load, the first aiming dot can be zeroed for 50 & 200 yards. The second aiming dot will correspond to a 400 yard aiming point. The third dot will correspond to a 500 yard aiming point. The fourth dot will correspond to a 600 yard aiming point.
Red Dot Mounting Base
The EXPOS3-4 comes with an integrated mounting base. The based is designed to be mounted on a standard MIL-STD 1913 Picatinny rail section. The integrated mounted based was designed to allow for quick and each attachment and detachment. The the mounting base is operated by a quick detach lever that allows for easy removal. The QD lever and mounting base can be adjusted to slightly different sized rails, as well as locked into a secure position to ensure that the unit holds zero.
The EOTech Holographic red dot sight is powered by a single lithium 123 battery. This battery allows the EXPS3-4 to operate for 600 continuous hours at nominal setting 12 while in a room temperature environment.
The EOTech red dot sight has 30 different brightness settings. This includes 20 daylight settings, as well as 10 addition night vision settings that are compatible with Gen I through Gen III+ night vision systems. This large variety of brightness settings allows you to choose the appropriate setting based on your shooting scenario.

This next generation model is more compact and lighter than previous models, making It much more convenient and comfortable to utilize. This new generation model also includes a greatly improved mounting base. The base is designed to attach to a 1” Weaver rail, as well as a MIL-STD 1913 Picatinny rail section. The mount allows for easy and rapid transitioning between 1x and 3x magnification views.
