Holosun HS515CM Micro Solar Red Dot Sight 2 MOA Dot 65 MOA Circle QD Mount ARD Black HS515CM UPC 605930624700

Product Description

The Holosun® HS515CM Micro Solar Red Dot Sight (SKU: HS515CM / UPC: 605930624700) is a hard-use, combat-ready micro optic engineered specifically for duty rifles, defensive carbines, and rapid-handling pistol-caliber platforms. Integrating Holosun’s advanced Multi-Reticle System (MRS), the HS515CM gives operators instant access to a crisp 2 MOA precision red dot, an expansive 65 MOA CQB ring, or a combined circle-dot reticle without shifting point of impact. Outfitted with high-efficiency 650nm Red Super LED architecture, the HS515CM delivers up to 50,000 hours of continuous operation from a single CR2032 lithium battery, reinforced by Solar Failsafe™ ambient light power backup for mission critical dependability.

Forged for severe operational abuse, the optical housing is CNC-machined from billet 7075-T6 aircraft-grade aluminum and treated with an abrasion-resistant MIL-A-8625 Type III Class 2 hardcoat anodized black finish. The enclosed 20mm optical tube is completely purged with dry nitrogen and submersion-sealed to IPX8 / IP68 standards, capable of surviving continuous immersion up to 30 meters for 30 minutes and withstanding 1,000 G of recoil impulse. Integrated protective side and top shrouds shield the 0.5 MOA coin-adjustable windage and elevation turrets against blunt field impacts, while high-grade multi-coated optical lenses maintain edge-to-edge optical clarity, unlimited eye relief, and parallax-free sighting under extreme weather conditions.

Every operational variable is covered out of the box: the HS515CM includes a quick-release (QD) lower 1/3 co-witness Picatinny rail mount, tool-less side battery tray for rapid cell replacement without optic removal, and an integrated Anti-Reflection Device (ARD / Kill Flash) that eliminates forward objective flash. Transparent rotating flip-up lens covers permit instantaneous emergency sighting even when closed, while motion-activated Shake Awake™ technology ensures the reticle instantly springs to life the millisecond the weapon is drawn or staged. With an Aimpoint® Micro compatible base footprint, operators can run the factory QD mount or integrate seamlessly with premier aftermarket high-rise and cantilever mounting systems.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Direct fit for MIL-STD-1913 Picatinny rails on AR-15, AR-10, MCX, MPX, SCAR, and railed carbines using the pre-installed quick-release lower 1/3 co-witness mount (1.63" optic height). Incorporates the industry-standard Aimpoint® Micro (T-1/T-2) 4-hole mounting pattern on the optic underside, compatible with Scalarworks, Unity Tactical, and Reptilia mounts. CRITICAL: HS515CM optical housing base adds ~0.060" to 0.080" of deck height compared to a standard Aimpoint T-2; an aftermarket "Absolute Co-Witness" mount will yield a lower 1/3 sight picture, and an aftermarket "Lower 1/3" mount will sit higher. If swapping mounts, apply non-permanent medium threadlocker (Vibra-Tite VC-3 or Loctite 242) to the four T10 Torx screws and torque to 12-15 in-lbs maximum. Do not exceed 15 in-lbs.

1. Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty in a safe direction.
2. Inspect the flat-top Picatinny rail cross-slots for carbon buildup or debris; place the HS515CM QD mount onto the desired rail slot, pushing the optic body firmly forward toward the muzzle to seat the cross-bolt against the forward recoil lug.
3. Close the quick-release cam lever; if the lever is loose or excessively stiff, open the lever and adjust the tension nut on the opposite side using the included multi-tool until the lever locks shut with firm, positive thumb pressure.
4. Install the included CR2032 lithium battery into the lateral battery tray (+ side facing down); slide the tray into the housing and snug the two T10 tray retention screws to 3-4 in-lbs (do not overtighten).
5. Power on the optic, toggle between the 2 MOA dot and 65 MOA circle-dot using the (-) button, verify Shake Awake™ auto-sleep functionality, and zero the optic at your chosen distance (50/200 yards recommended for 5.56 NATO) utilizing the 0.5 MOA click adjustments.

Key Features

• Red Multi-Reticle System (MRS): Select freely between a fine 2 MOA dot for precision engagement, a 65 MOA open ring for CQB speed, or a combined circle-dot reticle with zero shift in point of aim.
• Solar Failsafe™ Dual-Power Technology: Operates indefinitely using natural or artificial ambient lighting, automatically adjusting reticle intensity in Auto Mode while serving as an emergency failsafe during battery depletion.
• Shake Awake™ Motion Activation: Shuts down the LED during static storage to conserve battery life and reactivates instantaneously upon the slightest movement to the exact prior brightness setting.
• 7075-T6 Billet Aluminum Construction: Aircraft-grade aluminum housing with reinforced turret shrouds delivers 1,000 G shock resistance and severe duty survivability.
• IPX8 / IP68 Submersion Waterproofing: Fully sealed and nitrogen-purged monoblock chassis engineered for harsh maritime and wet-weather environments down to 30 meters.
• Quick-Release Lower 1/3 Co-Witness Mount: Fast, tool-free installation to standard 1913 Picatinny rails with adjustable clamp tension and optimal sight plane alignment for back-up iron sights.
• Complete Combat Accessories Included: Factory equipped with a honeycomb Anti-Reflection Device (ARD / Kill Flash), transparent rotating flip-up lens covers, and a tool-less lateral battery tray.
