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

It has been through about 370 rounds (About 250 were bird load) in 2 days. This HE510C-GR is great overall sight. Easy to use, easy to quick mount/QD (If it ever fails). It has an Eotech style reticle which is very crisp and clear; I'm settled with the 65MOA circle only for now since it's mostly for bird and 00 bucks. Most of my other sights are green(ACOG and RMR) because I can pick up that green reticle super quick and easy. No, it doesn't lose contrast when aiming at trees, I was able to hit two skeets this afternoon when they fly into the green leaves, and the range is also surrounded by trees. The fact it is solar and battery powered are great features for my use, and the auto on/off and brightness make this sight very smart. The auto brightness only goes from your setting to the max brightness is so thoughtful (which means I can change the minimum brightness anytime). And push both buttons can turn it off if I have absolutely no need to use the sight and push anyone to awake it to the previous setting is just convenient and will help extend the super long battery life. Shotguns in general are pretty rough on the sights, I had this sighted yesterday and it held zero just fine. The titanium hood has already protected the Al body from a few light scratches. The mount is pretty solid and I did try to QD it a few times for the training and it returned to zero no problem. This sight let me use the middle position for the M4's butt stock which is nice(as the picture is shown), the full length of pull is kind long for me, the middle position gives me less felt weight and shorter overall length (which makes the aim faster and less strenuously). It just let skeet shooting more fun and relaxing, and I can teach someone totally new to shotgun super quick on how to shoot it. I mean, shoulder the gun, both eyes open, put the circle on your target, pull the trigger (safely, of course), what can be more straight forward? Especially when you have a Benelli M4 with this sight? My friend(new to guns) started hitting flying clay within 5mins from I handed him the shotgun while teaching him how to use it.

Solid mount, vivid green optics, and great warranty.

This is an awesome sight. I like it better than my Eotech. I got the HE510C-GR because I wasn’t in the mood to spend another $600+ for a sight, but I really like my Eotech. I saw this and liked the fact that it comes in green so why not. I’ll probably sell my Eotech and use this instead and still have a big chunk of change leftover. The solar panels work great. I pulled it out of the box and turned it on and thought it already had a battery in it, it didn’t. The option to use dot, circle or circle/dot is nice. Adjustment is easy and so is mounting. After I zeroed it on my 300 AAC AR, I removed it using the quick lockdown lever, re-installed it and didn’t lose my zero. Also has a titanium housing around the front of the sight to protect it. And like all Holosuns, it has shake awake. The viewing window is also larger than the Eotech. My friends with Eotechs fired my AR with this sight and now they wanna get it for their other ARs as well. If Amazon had more stars on their review, I’d use them all for this sight.

I loved it so much I bought second one. Well worth the coin.

Awesome optic!

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.

works great on my smith and wesson fpc 10 mm. all 3 dot are clear and easy to see. brightness settings make it easy to see in any light condition.

Battery tray is stuck in the slot it seems. Used the pry tool after removing the 2 screws and bent the tab out..... Sight has a awful lens glare when at full bright in the dark. Reducing the brightness of course helps solve this issue. On a positive note: build quality is on point, the battery tray gasket is superb for me to not be able to pull it out; no water intrusion worries at all. Sight stability/movement after shooting is on point.

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。

何度ゼロイン調整しても、スコープほどの精度が出ない。ドットサイトにそこまで求めるのは酷かな？
