Holosun 1x Micro Red Dot Sight - HS507K-X2

The Holosun 507K X2 is a micro pistol red dot sight from Holosun with an M.R.S. (multi reticle system) and a modified RMSc footprint a.k.a. K Series footprint. The MRS reticle gives you a 32 MOA outer ring, and a 2 MOA center dot. The larger outer ring makes "finding the dot" a bit easier, and the 2 MOA dot makes precision shots easier to achieve. This micro pistol optic is designed to fit smaller handguns such as micro compact and subcompact pistols. It will fit on a K series slide directly (like on the Sig P365) but will require an adapter plate to fit on RMSc slides (like the Glock 43X MOS). The MRS reticle is also configurable, allowing you to use just the 32 MOA circle, or just the 2 MOA dot if you please. This durable red dot sight is one of the most popular red dot sights Holosun produces. It features a 7075 T6 Aluminum housing, sleek low profile design, side removable battery, shake awake, manual brightness mode, IP67 waterproof rating, 2 nightvision modes, and long battery life ranging from 20,000 to 50,000 hours depending on the reticle and brightness level. Holosun 507K X2 Reticle Freedom Gorilla Staff Review The 507K is an awesome site designed for concealed carry. Multi reticle system is a really cool feature that lets you use them both together or toggle through just a 32 MOA circle only or a 2 MOA dot only. The concept behind the 32 MOA circle is so you can easily find it better when drawing the gun. It even has rear dovetails to act as rear irons sights. The Holosun 507k is a micro compact reflex site made for sub compact pistols. It is the premium top of the line micro reflex sight holosun makes. It is a step above the 407k. It competes with the RMRcc, etc, etc. It has an open emitter, aluminum housing, comes in red or green dot versions, and weights 1 oz. The 507K has many of holosun&&';;s features such as shake awake, multi reticle system, long battery life, glass, etc. It has 2 nightvision modes and 10 daylight modes. The only thing this site doesn&&';;t have is solar charging, and auto brightness settings, which the 507c does. The battery will last 50,000 hours on setting 6 with the dot only reticle. With the circle dot plus dot it will last 10k-25k hours depending on brightness settings. Should be around 20k hours on setting 6. It accepts a CR1632 battery which is conveniently located in a side tray which means you don&&';;t have to remove the sight and risk losing zero when changing the battery. The MRS system is holosuns multi reticle system. It lets you choose from 3 dots, a 32 MOA + 2 MOA dot, 2 MOA dot only, or 32 MOA dot. Some of the benefits of the 32 MOA dot + 2 MOA dot are that it&&';;s easier to pick up upon drawing The size of the 507k is just under 1 inch wide, 1 inch tall, and 1.6 inches in length, the actual size is 1.6x0.98x0.95. The window size is 0.58x0.77 inches. The 507k is made out of aircraft grade 7075 T6 aluminum and is very durable, waterproof IP67 is certified tested to be 100% protected against solid objects like dust and sand and has been tested to work for at least 30 minutes under 6 inches to 3.3ft of water, and can withstand drop tests. The 507k comes with a manual, cleaning cloth, two set of screws with blue loctite already applied, and an adjustment tool for the turrets so you can change the elevation and windage as needed. Each adjustment click has a value of approximately 1 MOA or 1 inch at 100 yards (1/2" at 50y; 1/4" at 25y). When zeroing at 25 yard, if your impacts are 2 inches low and 1 inch right, you will need to adjust Elevation 8 clicks UP(counterclockwise) and 4 clicks LEFT (clockwise). The maximum adjustment range is 30MOA. You can get the 507k in both red or green dot versions. The green dot version is a little bit more expensive. If you are unsure of choosing red or green, green is a little bit brighter and easier for the eye to pick up. To learn more of the science see our guide on choosing red vs green dot here.
