EoTech 552 Holosight - Black XR308, 2 AA Batteries Included

The EoTech 552 Holosight is a proven combat optic that bridges the gap between daylight shooting and night vision work. Built around a holographic aiming system, the 552 delivers fast target acquisition in broad daylight and remains fully compatible with night vision devices when you're running Gen I through Gen III+ tubes. Whether you're setting up a patrol rifle, evaluating your home-defense carbine, or planning a hunting setup that might involve low-light conditions, this is the kind of red-dot equivalent that works equally well for both conventional and NV-aided shooting.

What makes the 552 stand out is its flexibility. Twenty brightness settings handle daylight glare without breaking a sweat, while ten additional settings are optimized for night vision compatibility—meaning you won't wash out your tubes or sacrifice performance when you flip on the NV. The sight is waterproof to 33 feet, runs on two standard AA batteries (lithium or alkaline, your choice), and returns to zero within 1 MOA when you remount it. That kind of repeatability matters when you're building a carbine you actually rely on.

The 552 mounts on any Weaver or MIL-STD-1913 rail, so integration into your existing platform is straightforward. At 10.9 ounces and compact dimensions (5.4 x 2 x 2.25 inches), it won't bloat your sight picture or throw off your gun's balance. The AA battery format is genuine convenience—you're not hunting down proprietary cells in the field, and alkaline ones will run 600 continuous hours on a set; lithium bumps that to 1000 hours if you're willing to spend a bit more per pair.

This is a sight for shooters who want daylight speed and night vision flexibility without compromise. It's been adopted by military and law enforcement for good reason: it works, it's durable, and it doesn't overcomplicate your workflow.

Frequently Asked Questions

Is the EoTech 552 night vision compatible?

Yes. The 552 is designed to work with night vision devices and includes ten brightness settings optimized for Gen I through Gen III+ night vision tubes. This makes it a smart choice if you're planning to integrate NV into your rifle setup.

What kind of batteries does it use, and how long do they last?

The 552 runs on two standard AA batteries. You can use alkaline, lithium, or rechargeable AA cells. With lithium batteries, you'll get approximately 1000 continuous hours of runtime at nominal brightness; alkaline batteries provide about 600 continuous hours. The inclusion of two AA batteries with your purchase means you're ready to mount and zero immediately.

Will the 552 fit my rifle's rail system?

The 552 mounts on any Weaver or MIL-STD-1913 rail, which covers the vast majority of modern rifles and tactical carbines. If your rifle has that standard rail configuration, you're good to go.

What happens to my zero if I remove and remount the sight?

The 552 will return to zero within 1 MOA when you remount it. While not absolutely perfect, this kind of repeatability is solid for practical carbine work and means you won't be chasing a completely new zero if you swap the sight between uppers or take it off for maintenance.
