The Holosun 403R is a red dot sight that is designed for rifles and other long-range shooting applications. It features a 3 MOA red dot reticle with an illuminated central aiming point, perfect for quick target acquisition and fast follow-up shots. The 403R also features 12 brightness settings for optimal visibility in a variety of light conditions. The unit is powered by a single CR2032 battery and has a battery life of up to 50,000 hours. The sight is waterproof and shockproof, making it ideal for use in adverse weather conditions. The Holosun 403R is an excellent choice for anyone looking for an affordable and reliable red dot sight for their rifle. The 403R’s competitive price point usually draws first-time red-dot buyers to make their purchase; what makes them stay is the realisation that despite the price, there is no compromise in quality! Such is why in recent years, Holosun has transformed itself into a leading manufacturer of firearm optics.

Given that the 403R is often paired atop a shotgun or rifle, Holosun has worked to ensure their sight is adequately equipped to handle temperature changes, dirt, rain and knocks that the firearm may endure. The capable and proven 403R is up to whatever is asked of it. This Red-Dot comes packaged with two mounting configurations, the lower 1/3 co-witness (ideal for AR-type rifles) and a low mount base for most other applications.

If you’re looking for a long-lasting red-dot sight, the Holosun 403R is your answer. This model has a battery life of up to 50,000 hours, or about seven years, with continual use. Even better, the 403R automatically shuts off after a set period of time when it is not in use, so you can expect your battery life to be much longer than seven years.
