Austrian optics manufacturer Kahles has released a new red dot sight called Helia RD. This is a non-magnified micro reflex sight with a 28mm width which makes it suitable to mount on handgun slides. Let’s take a brief look at the specs of this new sight.
Kahles Helia RD sight has a 2 MOA dot. The adjustments of the dot are described by the manufacturer as 15mm (.59″) at a 50-meter distance per click. The adjustment range is 4 meters and 2.5 meters at a 100-meter distance for elevation and windage respectively. The illumination level of the dot is also adjustable and has 4 brightness settings. The actual window of the sight has 26x22mm dimensions (1.02″x.866″). The overall weight is 42 grams (1.5 oz). Other dimensions (in millimeters) of this sight can be seen below.
The company also advertises an intelligent shut-off system called Automaticlight. Here is how it is described on their website:
The HELIA RD is equipped with a motion sensor. After being motionless for 3 minutes, the red dot turns off and enters “Standby” mode. In the “Standby” mode, the smallest movement is sufficient to re-activate the red dot in fractions of a second with the last selected brightness level. After 4 hours of inactivity, the red dot switches off completely.
The Kahles Helia RD sight also features an anti-reflective coating on the lens. The sight is powered by a single CR 2032 battery. According to the company, the battery is “easy to change”. The Helia RD sight comes with a Picatinny rail mount but it also has some sort of a direct mounting system – probably something similar to one of the most popular micro red dot sights. This sight also comes with a rubber cover that features a built-in spare battery storage compartment.
I couldn’t find any official information concerning the pricing and availability in the US market. If you Google the name of this sight, the results will show it listed on the website of B&H Photo & Electronics Corporation which is apparently a dealer of Kahles. The price on their website is $399 and they expect it to be available in 2-4 weeks.
