Holosun HE407K X2 Green Dot Reflex Sight 6 MOA w/ Shake Awake - HE407K-GR X2

The Holosun 407K X2 Green Dot is a micro compact pistol green dot sight that features a 6 MOA dot and a modified RMSc a.k.a. K-Series Footprint. It is intended to be used on sub compact and micro compact pistols with the properly cut slide. The 407K X2 will fit directly on slides that have a K Series footprint, but will require an adapter plate for pistols with an RMSc footprint. The 407K X2 is one of the best value micro red dot pistol sights on the market. It features a slim sleek profile, a strong 7075 T6 aluminum housing, side removable battery, shake awake, 2 nightvision modes, 50,000 hours of battery life, a bright emitter easily visible in bright sunlight, manual brightness controls, and IP67 waterproof rating. This tough and reliable pistol red dot sight from Holosun is one of their lowest priced micro pistol red dot sights. The 6 MOA dot is great for short to mid range. It&';s a nice size dot to pick up on the screen and to get on target quickly. This optic has a green reticle. Green has a few benefits: Green reticles are less straining for the eye to see. Green reticles can help with astigmatism. If you have astigmatism you will see a blurry dot, we have been told by a few customers that Green dots help with their astigmatism, making the dot look more crisp than the red version. Green will not washout on backdrops like green grass, foliage, or green colors. In theory Green dots can have a longer battery life because Green is brighter, so for example a green dot on brightness setting 6 may be the same brightness as a red dot on setting 7 - which would save battery life.

Holosun 407K X2 Green Reticle Freedom Gorilla Staff Review The 407K-GR is an awesome site designed for concealed carry. The concept behind the 6 MOA Dot 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 407K-GR is a micro compact reflex site made for sub compact pistols. It competes with the RMRcc. It has an open emitter, aluminum housing, comes in red or green dot versions, and weights 1 oz. The 407K-GR has many of Holosun&';s features such as shake awake and long battery life. 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 407c does. It also doesn&';t have the multi-reticle system like the 507k. The battery will last 50,000 hours on setting 6 with the dot only reticle. 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 size of the 407K-GR 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 407K-GR 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 407K-GR 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 407K 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.
