Eotech
The EoTech 558 Holosight is a combat-proven red dot sight built for shooters who won't compromise on speed, durability, or versatility. Whether you're running a defensive rifle, tactical shotgun, or competition carbine, the 558 pairs a crisp 68 MOA ring with a precise 1 MOA dot, giving you a reticle that works at close quarters and reaches out to intermediate distances. The side-mounted controls make it seamless to pair with EoTech switch-to-side magnifiers, and the quick-detach Weaver mount locks on and off without tools—perfect for shooters who rotate optics or need rapid transitions.
Built for real-world conditions, the 558 is submersible to 33 feet and runs on two standard AA batteries (included), with enough runtime to keep you in the fight for months of continuous use on a single set. Twenty daylight brightness levels handle everything from dawn to high noon, and another 10 settings unlock full compatibility with Gen I–III night vision—a rare feature that lets you keep the same sight when you go thermal or NV-ready. If you want to dial up aiming speed even further, EoTech's optional Laser Battery Caps (LBC and LBC2) drop right in, adding visible laser capability without changing the footprint of your setup.
At 13.8 ounces and compact in profile (5.6 x 2.2 x 2.9 inches), the 558 won't clutter your receiver or slow your transitions. This is the holosight that drives the guns of professional operators, competitive shooters, and serious hunters because it stays reliable when it counts.
| Reticle Pattern | 68 MOA Ring, 1 MOA Dot |
| Mount Type | 1 Weaver or MIL-STD-1913 rail (quick-detach) |

| Night Vision Compatibility | Gen I–III night vision devices |
Yes. The 558 is fully compatible with Gen I–III night vision devices and includes 10 dedicated brightness settings to optimize performance when used with NV equipment. This makes it an excellent choice if you're building a night-capable rifle platform.
The 558 is compatible with EoTech's drop-in Laser Battery Caps (LBC and LBC2), which replace the standard battery compartment cap and add visible laser aiming without altering the sight's footprint or function.
The 558 comes with a quick-detach Weaver/MIL-STD-1913 rail mount that locks on without tools and allows instant removal—perfect for shooters who rotate optics or need to co-witness with other sights.
On lithium AA batteries at the nominal setting, you'll get approximately 1000 continuous hours of operation. Standard alkaline AAs provide about 600 hours. Two batteries are included with the sight. Both rechargeable and lithium alkaline types are supported.
