510C Multi-Reticle 2 MOA Dot & 65 MOA Circle Open Reflex Sight - Solar FailSafe Shake-Awake, 12 Settings - Red/Green Reticle

Absolutely love this. It's my standard now for all my long guns. Very well made, durable, and the tech is awesome (auto sleep, solar failsafe, shake-awake). It just works without you having to think about it. Battery life is essentially a non-issue; I've had mine mounted and running for months without issue. The multi-reticle system works well, I run the circle-dot for fast target acquisition at close range and can switch to the 2 MOA dot when I need precision. Glass clarity and size is excellent, no distortion, and the 65 MOA circle is bright and crisp even in full sun. Mounting is solid, holds zero through hard use with no drift.

Quality dot here. Smaller and much less expensive than similar dots in this category. AND it has shake awake. Installation is a breeze with the lever. All in all - this is an awesome dot sight and I would even venture to say I like it better than the EOTECH EXP - but what do I know; it’s personal preference.

I have been using EOtech and wanted to try an alternative. This holosun is a good product. I have it mounted to an arms and it performed well. Was able to Zero it quickly. I’m happy with the purchase and would buy again. When comparing it to my EOtech: * the sights are clearer * has a little more features, * it’s slightly smaller * looks not as heavy duty (but I’m not trying to drop or bang it around).

I’ve been using the HOLOSUN HS510C-FDE-R Red Multi Reticle for several weeks now, and it has exceeded all expectations. Right out of the box, the build quality is impressive—rugged, well-machined, and the FDE finish looks fantastic on my rifle. Multi-Reticle System: The ability to switch between a 2 MOA dot, 65 MOA circle, or both is incredibly useful. It gives me flexibility for both close-quarters and precision shooting. Solar + Battery Power: The solar failsafe is a brilliant feature. Quick Detach Mount: The QD mount is solid and makes it easy to move between platforms without losing zero. Wide Field of View: The glass is crystal clear, and the sight picture is wide and unobstructed. Target acquisition is fast and intuitive. This optic is perfect for anyone looking for high performance without the premium price tag of other brands. It’s held zero through hundreds of rounds and rough handling. I’d absolutely buy it again.

Best green dot sight I own. Shake awake feature with auto on and off are the features I was looking for. I love the different reticle options and the green is highly visible. Holds zero incredibly well at 25 yds on my 9mm Pcc. Battery life is great with the solar fail safe just makes this an absolute must have for any firearm that allows for a picatinny mount. I would absolutely recommend this product.

High quality, built tough, worth the money

I've had an RMR and a few Vorted red dots. The RMR had the dimming issue I resolved with an antiflicker plate and I loved it. The Vortex dots aren't sexy but they just work. I could punch a penny at 25 yards with both. This new Holosun however beats them all. The features, construction, and options put it above the competition at almost half the price. Perfect cowitness with the BUIS that came with my B&T GHM9. Took a considerable amount of left to right adjustment, but the up down was dead on. The shake to wake feature gives it true "Go Gun" status. No fiddling with buttons to turn it on. In a bad situation you don't want to have to try to turn one on when you really need it. Pulling it out of your bag will bring it to life and you're ready to rock. Autodimming is also a great feature my RMR and Vortex dots didn't have. Once enabled you will see a noticeable and immediate difference going from dark/dim to brighter areas. Works excellent outside. The feature is disabled by holding the + button for 3 seconds. This would be ideal if you're in a shaded environment and your target is outside in a brightly illuminated area. In the higher brightness settings you can still see the reticle when you point it towards the sun. You won't lose your dot in bright areas. The reticle options are also very hand. 2moa dot will help you plink pretty far down range and the larger 65moa reticle will give you fast acquisition at closer range. They defiently both have their place. And neither the RMR or Vortex dots offered multiple options. The battery life is supposed to be incredible. I haven't had it long to know, but all testing has shown you'll have years between battery changes. Keep in mind it does come with a spare battery tray so you if your grip has storage you can keep the included torx tool and spare battery with you when it becomes an issue. The solar feature is reassuring. Worst case scenario youre in the field or fight and the battery dies. If you are outside in the sun, or have enough ambient light the dot will still work. If SHTF and batteries are no longer available, you'll still be able to use it. The value, man.. It is just a no brainer. Half the price of an MRO or RMR. More features. More rugged design. The Alamaba Arsenal torture test includes, pouring water on it, throwing it 20ft into the air and letting it hit the ground, freezing it in ice, beating on it, and SHOOTING it with a shotgun, and it still held zero. The quick release mount also saves you an extra $150 if you were running other dots and allows for a perfect BUIS cowitness. Mine fit a little loose when I first installed it. I used the included tool and tightened the mount one turn and it clamped down with the force of an Amazonians thighs during Snoo Snoo. Absolutely solid now and still easy to release with the convenient latch keeper. The picture is incredible. The thinner profile sides and large viewing window give a natural feel and you're not chasing the dot around. No toilet paper tube EFFECT or black glob in the corner like with the Vortex Sparc AR. With boys eyes open you hardly notice the frame. You just see everything as well as a dot in your FOV. I will probably buy another one for my next Scorpion build. Can't imagine anyone coming out with a better optic for the money.

Holosun is great and costs less than some competitors. You can't go wrong with their extended battery life and solar power. I have this on a shotgun. I didn't even need to make any adjustments; it fired straight and true right out of the box. My last optic was a true holo-sight; and it required a lot of adjusting. I should have purchased a Holosun back then.

10/10 would recommend - YouTube has some great durability videos on this red dot. You’d be surprised at how big of a beating this thing will withstand !

主にインドアメインで使ってますので野外での使用感は分かりません。動画の通りローライト戦でもレティクルが明る過ぎず暗過ぎずくっきりと見えます。レプリカも見かけないし、インドアでは510c自体殆ど見ないので、他人と被りたくない個性を出したい方にお勧めします。自分はつぼみアームズ様から購入しましたが、以前別の光学機器でアフターサービスが完璧だったのと購入後にお手紙を頂くなどアフターフォローもして頂けるので、購入はつぼみアームズ様をお勧めします。

M4 mwsに取り付けてます。オープンサイトで視野を確保しやすく、透明度が高く、とてもいい製品だと思います。 レプリカを何度も買い直すより少し値が張ってもこっちを買った方がいいです。

Eotech製品よりも装着時のバランスが良い。 今回はFD色にしたがコヨーテタン寄りの色味で悪くはない。 中型一眼レフにオススメ。

Optic has work perfectly!
