NEW Bul Optics MS-3 Red Dot Sight
Bul Optics, a division of Israeli Bul Armory, has added the third sight to their line of handgun red dot sights. The new RDS is called MS-3. We’ve previously reported about the launch of this sub-brand and their MS-1 and MS-2 sights. Let’s see what features are packed in this new red dot and what are the differences compared to the other two products in the Bul Optics catalog.
Bul Armory @ TFB:
Probably the main difference from the MS-1 and MS-2 is that the new MS-3 sight has a side battery tray which will allow replacing the battery without having to uninstall the sight from the gun. The MS-3 is powered by a CR2032 battery and has an advertised battery life of 20000 hours on the “weakest visible dot” out of eight dot brightness settings. The dot size is 4 MOA. The windage and elevation are adjustable.
The housing of Bul Optics MS-3 red dot sight is made of 6061-T6 aluminum. The mounting footprint is compatible with Trijicon RMR. This sight is IPX6 waterproof and is rated to operate in -4°F to +131°F (-20°C to +55°C) environmental temperature conditions. The MS-3 sight weighs 1.8oz (51g) and has the following dimensions: length – 1.78″ (45.2mm), width – 1.25″ (31.8mm), height – 1.1″ (28.2mm). The window size is .73″ x 1.12″ (18.7mm x 28.5mm).
The MSRP of this new red dot sight is not specified by the manufacturer. What price range do you think would make this sight competitive in the modern saturated market of handgun reflex sights? What features do you think are must-haves on a red dot sight that this one lacks? Sound off in the comments section.

If it's "20000 hours on the 'weakest visible dot'," I wonder what the battery life is when you ramp it up to Florida-Sun-visible level. I'm assuming these are manufactured in China (look like Holosun designs--like what SIG and others do). So they should add motion-on/off to get the battery life up to something that will last 6 months when bright enough.
I didn't think I would appreciate it but motion activation is a really great thing. It's ready when you need it but saves battery life.
I stay away from auto bright and auto off features. Those light sensors are unreliable and often wasteful and some think you will never ever need to shoot in a dark setting.
