Eotech 512.A65MO Review

Eotech 512.A65MO Holographic Weapon SightThe Eotech 512.A65MO Holographic Weapon Sight (HWS) is configured with a 1 MoA dot in a 65 MOA ring reticle for fast shooting of moving game, predators and varmints. The 1 MOA dot enables precision out to the range at which the target can be identified. To extend this range by several hundred metres an Eotech G23.FTS 3x magnifier can be mounted behind the holographic sight. This flips to the side to enable use of the HWS at close quarters. Aimpoint magnifiers can also be used with the Eotech. This HWS is supplied with a Mossy Oak Obsession finish to coordinate with similarly camoflaged weapons and clothing.

The Eotech 512.A65MO HWS employs the latest solid-state electronic technology. No less than 20 brightness levels enable the Eotech 512.A65MO to adapt to any lighting conditions. The battery check indicator, up/down brightness scrolling and (programmable) auto shutdown are controlled by an on-board microprocessor. The electronics are protected by encapsulation in a shock absorbing resin compound.

The holographic patterns are visible in any light, center instinctively regardless of weapon hold, and remain visible while sweeping the area. Reticles are large and semi transparent to ensure the fastest possible shot without obscuring the target.

The HWS utilizes a fighter jet style ‘Heads-Up Display’ (HUD) that eliminates the obstructions and restricted angle of vision associated with other types of unitary power sight. This is a key advantage Eotech vs Aimpoint. The controls do not protrude from the Eotech 512.A65MO’s streamlined housing and nothing obstructs the view of the target area. You keep both eyes open whilst shooting, ensuring full situation awareness and rapid shooting.

Partial obstruction of the window will not prevent aiming. In the unlikely event that the window is shattered, the Eotech will remain fully functional! As long as you can see through any portion of the window, the entire aiming pattern will be visible on target and you can shoot accurately. This is just as well because Aimpoint vs Eotech the Aimpoint is easier to keep mud and snow out of with its sealing lens caps.  A set of Lens caps for the Eotech 512 are now available from GG&G, but, due to the Eotech’s configuration these don’t seal in quite the same way.

The Eotech 512.A65MO has been tested in the most extreme conditions and will perform consistently and reliably in any hunting environment. It is proof against water, fog, shock and extremes of temperature.

The HWS has been subjected to military drop tests and consistently remained operational and held its zero. Other tests utilized a recoil simulator to subject the sight to 3,500 Gs of acceleration in under 0.5 milliseconds (this approximates to mounting on a .454 Casull handgun) as well as chambers simulating various environmental conditions.

The HUD is made of 3/16″ thick, three layer, shatterproof laminate glass for extreme durability. For additional protection a rugged ‘roll bar’ hood covers the optical components of the sight.

The Eotech 512.A65MO does not project any radiation or give off any visible signature that could give away your position or spook game or wildfowl.
