Holosun HS515CM Solar Red Dot Sight BK

Holosun HS515CM Micro Red Dot – Hard-Use Rifle Optic

Holosun’s HS515CM is a 20 mm enclosed red-dot engineered for carbines, PCCs, and duty rifles that see real abuse—not just range days. The sight pairs a fully sealed 7075-T6 aluminum tube with a titanium-reinforced hood, Solar Failsafe™ redundancy, and a tool-free side battery cap for field reliability.

Core Technologies

• Multi-Reticle System: choose a 2 MOA dot for precision or a 2 MOA dot inside a 65 MOA ring for speed—switch without re-zeroing.
• Solar Failsafe: the integrated panel powers the LED and auto-adjusts brightness when ambient light is available, keeping you in the fight even with a dead battery.
• Shake Awake: a motion sensor wakes the optic instantly and pushes battery life to 50 k hours on setting 6 with a single CR2032.
• IP68/IPX8 sealed: submersible and dust-tight, verified to 1 m+ for 30 min and shock-tested to 1 000 G.
• QD Lower 1/3 Mount: factory 1.63″ height ensures iron-sight clearance; one-hand removal lets you swap optics or clean the gun fast.

Technical Specifications Holosun HS515CM

Field Benefits

• Rapid sight picture—wide 20 mm aperture and lower-third mount keep the target and irons in the same plane.
• Works in any light—auto-brightness via Solar Failsafe plus two night-vision levels for NOD users.
• Zero confidence—0.5 MOA clicks let you dial in a 50/200 m combat zero without guesswork.
• Lens protection—clear rotating caps and a removable kill-flash reduce glare and keep glass intact in dense brush.

Real-World Scenarios

• Hunting driven boar at dusk—switch to the circle-dot for fast acquisition under tree cover.
• Dynamic carbine matches—Shake Awake wakes the dot as you transition from staging area to buzzer.
• Law-enforcement patrol rifle—Solar Failsafe guarantees a daylight-bright reticle even if the CR2032 is cold-soaked or depleted.

Installation & Zero

1. Clamp the QD base on any MIL-STD-1913 rail; verify full latch engagement.
2. Fire a 3-shot group at 25 m, adjust 0.5 MOA clicks until POI matches POA.
3. Reconfirm at mission distance (50 / 100 / 200 m) and lock turret caps.
