Part number 512.A65 confirmed. Here is the finished description:
The EOTech Model 512 Holographic Weapon Sight (512.A65) is a full-size, aluminum-bodied holographic sight that runs on two AA batteries and delivers a 65 MOA ring with a 1 MOA center dot reticle for fast close-quarters acquisition and precise mid-range shooting on rifles, carbines, and shotguns. Built for shooters who want a battle-proven holographic weapon sight for AR-platform carbines, home defense builds, or tactical competition, the 512.A65 brings heads-up display performance and unlimited eye relief to any standard Picatinny or Weaver-equipped firearm.

Special Features
- The holographic reticle pattern remains fully visible and point of aim stays accurate even if the lens is partially obstructed or cracked, a capability that standard red dot sights cannot match.
- The 65 MOA outer ring equates to approximately 68 inches at 100 yards, giving you a built-in reference point for estimating range, reading shotgun patterns, and leading moving targets without guesswork.
- The integral mount uses a tool-less knobbed bolt that locks directly to standard Weaver and Picatinny rails, so you mount and remove the sight without carrying extra hardware or wrenches.
- Anti-glare coatings on both the front solid glass and rear shatter-resistant laminate windows reduce lens flare and maintain a clean reticle picture in bright sunlight and harsh lighting environments.
- The AA battery format gives you a long-runtime optic powered by batteries available at any hardware store, gas station, or sporting goods retailer, which matters in the field where proprietary cells are hard to source.
- The programmable auto shut-off protects battery life between uses and can be set to 4 or 8 hours depending on your operational preference.
Practical Benefits
- The 65 MOA ring lets you find the reticle and get on target almost instantly in close-quarters situations without hunting for a small dot, while the 1 MOA center aiming point gives you the precision needed at 100 yards and beyond.
- The unlimited eye relief and heads-up display keep both eyes open and your full situational awareness intact, which makes the 512.A65 a natural fit for home defense carbines, three-gun competition, and fast-moving field scenarios.
- The shatter-resistant rear window and rugged aluminum hood hold up to hard handling, rough transport, and extended field carry without babying the optic.
- The 512.A65 is magnifier compatible, and because the holographic reticle does not scale up with magnification power, adding a 3x or 5x magnifier behind this sight gives you a clean, precise dot at distance without reticle bloom.
- Your 512.A65 gives you a holographic platform that runs on batteries you can find anywhere and mounts to any standard rail without tools, removing two of the most common friction points in fielding a dedicated optic.
The EOTech Model 512 Holographic Weapon Sight (512.A65) with its 65 MOA ring and 1 MOA dot reticle is a proven platform for carbine shooters, home defense builders, and competition shooters who demand fast acquisition, durable construction, and a field-ready battery solution.
