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

High quality and functional. No issues when in use. Long battery life, sweet shake awake feature and easy to use.

Wonderful, well built site. Solar back up power that works great. Easy to install and holds solid. Clear glass with easy to see reticle. Holds its zero well even after a lot of shooting.

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.

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.

This item was perfect. Just what I wanted. Makes my m4 complete. Easy to install, multi reticle, looks good.

Holosun is a fantastic optic, Yes it is made in China and they are making a very durable and top of the line product. Excellent sight picture ,very clear and durable optic, I shoot a lot and I believe this is my eighth one I have purchased for the collection of rifles I have, I own EOTECH and many others, there is nothing more durable than EOTECH but this comes pretty close when you look at it has solar so you really never worry about it working, shake awake, fog and water proof, night vision capabilities, reliable to zero every time, don’t worry about the battery and don’t forget to buy a cheap cover to go with it, you really can’t go wrong with any of the Holosun line

Great unboxing experience and easy to install. Went to a friend’s outdoor range and put over 500 rounds chambered in 556 ammo and optic never moved out of place. The functionality and placement of the buttons feels nice and tactile. Time will tell with battery life but I’ve owned other optics from Holosun and it’s never been an issue. It is lightweight and doesn’t add much weight when mounted on an AR-15. Shoutout to the staff at Holosun for engineering a superb red dot. Build quality is phenomenal and value for money, 100% worth it in my honest opinion. It is zeroed from factory and can easily hit a small steel target from 100 yards. I love that about Holosun. No complaints about this optic so far!

Bought this sight in 2019 for $275. It is still working great. I have had some issues over the years with picking the optic up and it not being on. Im not sure if it was to do with the settings or what but I would think it was on auto off standby mode but I had to adjust it a few times before I could trust that it would just be on instead of being off because it was in one of the modes that the sight has that affects battery comsumption. So be aware of that if your using this for duty. It has clear glass and dot. It feels durable and has lasted well with being knocked around during normal use. Easy to install, just double check the mode settings before you set and forget. Love the look of it as not many other optics have this exact footprint. It has a look of its own like an eotech

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。

I bought this for my 45/70. I was a bit worried about the recoil but after some research I found out that this red dot can handle a lot of recoil. The sight is very clear, reticle is nice and crisp. I would buy again.

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。
