Holosun Turret Cap, 1x Product description

Holosun Turret Cap (Original Factory Part)

The Holosun Turret Cap is a genuine OEM replacement part made by Holosun to ensure a perfect fit and reliable performance for your optic. This is the exact same turret cap included with new Holosun red dot sights — not an aftermarket or third-party component. Designed to protect your windage or elevation adjustment turret, it helps maintain your optic’s zero while shielding internal mechanisms from dust, moisture, and impact.

This original part is essential for shooters who need a factory-correct replacement or a spare in their range kit. Built from durable materials and engineered for a secure, snug fit, it’s ready for real-world conditions.

Key Features

Authentic Holosun-manufactured turret cap — not a replica or third-party version
Compatible with both windage and elevation turrets
Raised tab on cap allows for turret rotation without additional tools
POI movement direction is marked inside the cap for easy adjustment
Ribbed edges provide better grip, even with gloves
Durable and weather-resistant for tactical and outdoor use
Available in black only — matches factory optic finish
