After extensive testing of various optical sights, US Special Operations Command has standardized on the HWS as its 1 X weapon optic for close quarter, urban combat zones. To meet the stringent requirements set and demanded by our elite fighting forces, L-3 EOTech has developed the SU-231/PEQ (Model 553), modeled after the ever popular, battle proven HWS design. The SU-231/PEQ (Model 553) incorporates many additional features required within the SOPMOD Block 2 program.
* Dual quick-release throw levers for instant attachment
* Powered by two 123 Lithium batteries, allowing cross application with other electronic gear
* 7mm (1/4") raised base to provide an operator a consistent cheek weld with all other standardized optics
* 66 (2ATM) feet water submersibility
* Battery cap tether to avoid loss in the field

Night Vision Compatibility
The Model 550 series of sights, which includes the Model 553, Model 552, and Model 551, are fully compatible with all generation levels of night vision intensifier tubes. A special night vision (NV) setting allows the operator to immediately drop the brightness intensity of the holographic reticle to eliminate any "halo" affect while viewing through an image intensifier tube. The Model 550 series can be positioned in tandem behind night vision image intensifiers without any "bloom" of the target area. Now operators can combine the proven night vision technological advantage with a superior, close quarters weapon optic to achieve greatly enhanced weapon aiming - in complete darkness.
Unlike active IR laser pointer systems, the HWS is a passive system and emits no muzzle side signature. While in the NV mode, the HWS is undetectable against enemy night vision surveillance systems, providing operators with a stealth means for effective nighttime weapon aiming.
The Model 550 series' unique switches allow the operator to instantly drop the holographic reticle's brightness to the NV mode of operation. The operator has the ability to toggle back and forth between the NV mode and the normal day/night operation within fractions of a second. The Model 550 series has 10 distinct night vision settings to provide maximum flexibility to the operator. Typically, 3 to 4 brightness settings are not enough to support a host of constantly changing conditions including manufacturing variances in the sensitivities of the image intensifier tubes, varying ambient light environments, and varying light gathering sensitivities of the human eye across users. The Model 550 series still maintains the 20 normal brightness settings for normal day/night operations
The typical configuration is with both the monocular night vision system and the HWS mounted in tandem on the weapon's receiver. Operators can also witness the holographic reticle with head/helmet mounted monocular night vision image intensifier systems, even on a partial cheekweld on the weapon's stock. This allows the operators added flexibility and greater versatility when deploying with night vision systems in the ever changing battlefield environments.
No Revealing Signature
The HWS is a passive weapon optic and does not emit any muzzle side, position revealing light signature. The projected reticle pattern is visible only to the operator. Even Gen III night vision equipment cannot detect muzzle side signature of the operator's position.
The result - the operator remains absolutely undetectable in any operating environment
No Reticle Wash-Out
The HWS's 30 brightness settings (10 settings in NV mode Model 55) ensure the holographic reticle can be instantly viewed in ALL types of lighting environments, cluttered backgrounds and target colors. The HWS delivers an impressive 50,000,000:1 bright to low reticle contrast ratio to ensure the reticle is always clearly viewable.
Reticles can be easily seen against white targets in full sunlight - even in desert or tundra environments. With the HWS, there are no reticle "wash out" conditions as seen in red dot sighting systems. Operators can then adjust to work in moonlit or super low light environments against dark colored targets without "overwhelming" the target scene. For extreme low light conditions, engaging the HWS's night vision mode allows the reticle pattern to be viewed in tandem with the most advanced night vision systems on the market today. The 30 brightness settings provide the operator the flexibility to adjust for optimal conditions in today's ever changing battlefield environments.
