Hiram Green Red Dot Sight 1x20mm Micro Rifle Scope 4 MOA Reflex Sight with Illuminated Reticle and 7 Brightness Levels, 20mm Picatinny Rail Riser Scope Mount, Waterproof Fogproof Tactical Accessory

Works great on my 22LR rifle. For the price, it is a good deal. It has both red and green dots, which are very easy to see. Easily mounted to any rail. A good red dot for the price!

UPDATED FROM BELOW: Having tested this on my carbine now, here’s what I would add to what I wrote previously. Click adjustments are positive, and in the bright sunlight I could make out super tiny arrows designating which way to turn for wind age and elevation adjustments. Held zero perfectly. Brightest settings were OK in sunlight, especially green. Still consider it 5 stars for the money. PREVIOUS REVIEW:This has to be a limited review as I have not fired the Beretta CX4 9mm carbine with sight attached yet. I will follow up after a couple hundred rounds if there are any performance issues. Here’s what I can say: the sight is close to advertised, with a few things slightly different than pictured. The top buttons are not designated with red or green. The sight is labeled PINTY on the left side. There are no arrows or letters designating which direction to rotate turrets for right/left, up/down. Other than that, it seems to be built well and operation of buttons are positive and solid. Dot clarity seems excellent on red, if not overly bright. Green provides plenty of brightness but flares out a little more. All in all - especially considering the price - if this sight holds up to recoil as expected, it is a great value and meets the purposes for which it is intended. BTW, it is replacing the classic Bushnell TR25 that shorted out. I also own a Sig Romeo 5 and an Eotech. I would not compare the Hiram sight to either of those fine sights, but I think it is worth the money.

First, let me start by saying that I have NOT yet field tested this sight. I just received it today with Prime 2 day shipping coming through despite the pandemic. Anyway, so far so good! Better than expected feel of quality. Positive button response for adjusting the dot brightness. Dot is crisp and clearly round. Red could be a little brighter in my opinion, but for $32 and the green being plenty bright, it's not a deal breaker. Mine happened to come with an extra pic-to-pic riser (bonus?). I have it mounted without either riser to a Marlin 795 with the help of a UTG dovetail-to-pic/weaver snap in adapter, and it's nice and secure. Nice positive clicks on windage/elevation adjustments. Overall really happy with it so far. Can't wait to get out and shoot with it! 4 stars only because, as I said, I haven't shot either it yet so I can't give it 5 without knowing if it holds zero.

This is a very good low budget reflex sight. I was pleasantly surprised that the sight stayed zeroed. I had no problems of fogging. The dot may appear slightly distorted but did not effect target acquisition. The picatinny riser mount is also a plus, because it allows line-of-sight to mechanical sights without removal.

This RDS is a great budget sight that has the T1 type mounting allowing it to be used on the Midwest Industries' Keltec Optic Mount T1/T2 (which is a great Optic Mount that twists to allow it to fold incredibly). I was searching for a budget mount and many did not have any reviews stating as such. This sight has both red and green dots which is a plus. It is well built and small enough to be used with the Keltec. I also have the Sig Romeo5 and it is a tough choice between the two. So far, this sight is the winner with having both red/green dots. It has auto shut off and memory setting, just like Romeo. Durability between the two will take time with use to see, but as of now, this Hiram sight is the winner at 1/3 the cost of the Romeo5.

I've searched everywhere for a cheap rex dot for airsoft that has a true t1 footprint so I can use my riser mounts ( unity fast, hydra) . I finally found one. This is super fair priced, and it's 100% t1/t2/romeo 5 footprint. Feels sturdy. Great for airsoft

UPDATE: I decided to return both red dots. I'm sure the company may reach out, but I do not wish to keep using them. The units were not defective, and both held zero well. However, I used my own brand new Duracell 2032 batteries, and not the included batteries as some have said they are DOA. Even on the 7th click, brightest setting, outside they can be seen against a target or even the sky, but they're not quite bright enough for my purposes. I don't like running them at their max setting just to see the dot. Otherwise, they're good, if you don't play on using them in hardcore bright settings. My two cents. Otherwise, everything I've covered was fine with my two. This red dot review will cover only the initial stuff, and some questions I myself had, that seem to need clarifying or the manufacturer has made some positive updates. I WILL be updating the review once I have gotten some range time on it, and let people know if any issues arise. I did pay for this unit today, and it showed up within 2 hours, so good on Amazon for that speedy delivery. I opted for this unit as I just need a red dot, fast, and I know and like these economical red dots. I'm not deploying next week, and if you're into expensive gear, you're not reading this. So, I run good, economical red dots on my ARs. I have several, from the TWOD that looks a lot like this one, to a Fieldsport RED DOT ONLY or two, to the CVLife stuff, and they all seem to have mostly positive attributes. The main questions I had as I was reading these reviews earlier today, was saved last brightness setting, and auto off after 1 hour. I was sad when some were saying it did not, even though the TWOD, which looks nearly identical, does have those features. My Hiram unit I got today, does have last brightness setting remembered, but for both colors. Leave it at setting 4 RED and then turn it on next time for GREEN, and it'll be 4 GREEN, etc. Also, it does shut off after 1 hour of inactivity, as I've tested that feature over 3 one hour test periods. I did give the unit several sharp taps with my palm, to see if mine was 'loose' as some negative reviews have said. No issues. I will also, per some negative reviews, do my due diligence... And remove the mount screws with a properly sized (Yes, properly sized because the hardware with less expensive units can be softer steel, and too large or small a screw driver will screw you, pun intended) philips head screw driver and apply a touch of loctite to any screws that could work themselves loose. Yes, it should be handled my the manufacturer, but price vs features is the name of this game. A little extra work on your part, will make these economical red dots run well. Of every lower cost red dot I've run, I don't have zero shifting issues, and stuff doesn't work itself free over many rounds. Don't throw it at a tile or concrete floor, either. Main mount that it came on, and is on in my picture, tightened right up on my Aero upper, and any mil-spec upper won't have issue. Some aftermarket rails, however, can present issues. American made rails, not as much, but even some of my range guns have imported rails. Gently, crank the mounting screw down, but don't go nuts and strip the screw right out. You should get it to mount tight on any picatinny rail that isn't terribly small out of spec, by just tightening half past snug. Fire a few rounds, check it, and check periodically and you'll be fine. Lens coating is silver like the pictures, and doesn't darken the view much at all, but it does a tiny bit. My dots both red and green seem clear enough, and I have confirmed through several red dots, including an Aimpoint PRO, that I have an minor astigmatism that even presents itself in something like that Aimpoint PRO. Dot isn't splotchy beyond use, and that's typically not the unit itself, but our eyes. Mine came as in my picture, with the high riser, and the lower mount, and then the 3rd surprise light weight mount. Don't know if that was a fluke, but I'll TAKE IT. It also came with a battery, lens cloth and tiny wrench not pictured. I threw a Duracell 2032 I know is brand new in, to confirm function. Another smaller question I had with ambiguity in some reviews, I was happy to see it says and takes 2032s and not some obscure 2016 type battery. As I've said, I've run a lot of bargain red dots. You make sure a couple small things are good, and add a bit of loctite if needed, know how to really zero a specific weapon system and you'll be alright. If it's a duty gun or some such, then yeah, get an Aimpoint. I don't always review each red dot I get, but since I had some questions, hopefully this will help clarify what you'll be getting as of this writing time frame.

The price point and actual specs of it. It's hella worth it. The build is pretty good and it's actual somewhat a T1 spec, so that fits most modern day risers and it holds 0 due to the actual cut in. Overall if you're looking for an affordable T1 replica. This is the thing to get and also

Never really thought about having astigmatism or noticed anything was really wrong until I bought this lol The optic itself is great, excellent build quality for the price and arrived a day early! I cannot use the green dot but the red is fine on the lower settings and my wife who has perfect vision says both the green and red dots are clear except on the brightest setting when they get a little bit funky but it's nothing really too bad. I mean anyone who buys an optic in this price range and complains about something as little as that are the same type of people that require us to have a hot warning on a coffee cup...

Very happy with description fit it to a T

Great product, exactly as advertised!

Works okay, hard to calibrate as it's so small. Will probably go with a longer scope next time for better accuracy.
