Holosun HS407COMP‑RD6 Compact Competition Red Dot Sight with Shake Awake™, 1× Reflex, CR16340
The Holosun HS407COMP‑RD6 open reflex red dot sight is a compact, lightweight reflex optic measuring 45×33×32 mm and weighing 48 g, designed for sport‑shooting, competition‑style pistol platforms, and airsoft setups using an RMR‑compatible rail footprint. The sight features a 1× non‑magnified optical system with unlimited eye relief, aspheric multi‑coated glass, and a 28×22 mm large‑aperture window that delivers a wide field of view and fast target acquisition. The central aiming point is a crisp 6 MOA red‑dot reticle delivered by an LED, providing excellent visibility against bright or contrast‑rich backgrounds without requiring you to close one eye during fast‑paced scenarios.
A key feature of the HS407COMP‑RD6 is side‑access battery replacement using a CR16340 3 V lithium cell. The battery tray can be removed and replaced without detaching the optic from the rail, so shooters do not need to re‑zero or remount the sight after each battery change, a major advantage for competition‑oriented, high‑frequency shooters and professional‑style users. The sight offers 12 brightness levels: 8 daylight modes plus 4 night‑vision‑compatible (NVD) settings, giving users full control over the red‑dot intensity in sunlight, overcast, or low‑light conditions. The Shake Awake™ motion‑sensing feature places the dot into low‑power sleep mode when the device is idle and wakes it instantly with small movement, significantly extending battery life and keeping the optic ready‑to‑go between drills or training sessions.

Frequently asked questions
What is the Holosun HS407COMP‑RD6 open reflex red dot sight used for?
The Holosun HS407COMP‑RD6 open reflex red dot sight is designed for fast, both‑eyes‑open aiming on pistol‑style platforms, rail‑top adapters, and airsoft setups with an RMR‑compatible rail footprint. The 6 MOA red‑dot, 12‑brightness‑level LED system, and Shake Awake™ technology make it a practical choice for sport‑shooting drills, competition‑style training, and airsoft scenarios where speed, reliability, and long battery life are more important than optical magnification.
How long does the Holosun HS407COMP‑RD6 battery last?
The Holosun HS407COMP‑RD6 runs on a single CR16340 3 V lithium battery and is designed for “tens of thousands of hours” of typical LED operation at moderate brightness levels, especially when combined with Shake Awake™ power‑saving logic. In everyday use this can translate to several years of operation with very few battery changes, even for frequent sport‑shooting sessions or regular field‑use. The side‑battery‑tray design means you can swap the cell without taking the optic off the rail, so the system stays ready‑to‑go with minimal downtime.
How does the Shake Awake™ system work on the HS407COMP‑RD6?
The Shake Awake™ system on the Holosun HS407COMP‑RD6 uses motion‑sensing logic to detect when the optic is idle. When the device is not moving, it switches the 6 MOA red‑dot into low‑power sleep mode, greatly extending the battery life. As soon as you pick up the platform or make a small movement, Shake Awake instantly wakes the dot to the last‑used brightness level, ensuring the sight is immediately ready for fast‑paced shooting without manual re‑activation.
Is the Holosun HS407COMP‑RD6 suitable for airsoft and sport‑shooting platforms?
Yes, the Holosun HS407COMP‑RD6 open reflex red dot sight is well suited to airsoft and sport‑shooting applications thanks to its compact 45×33×32 mm, lightweight 48 g design, large 28×22 mm window, and 1× parallax‑free view. The 6 MOA red‑dot, 12‑brightness‑level system, and RMR‑compatible mount make it easy to integrate onto airsoft replicas and pistol‑style sport‑platforms. Its robust 7075‑T6 aluminum, IP67 rating, and 5000G impact resistance also ensure the optic can handle the types of vibration and impact associated with active‑play airsoft fields and high‑round‑count range use.
What warranty does Holosun offer for the HS407COMP‑RD6 in the EU?
