If you’re looking for a sight that expertly combines affordability and performance, the Feyachi RDS-25 Red Dot Sight is an outstanding choice. There are 11 different brightness settings for you to cycle through, and it comes with two different mounting options, so you won’t have any problem getting a perfect fit for your Ruger.
Even better, it has a long-lasting battery life, with it typically lasting anywhere from 150 to 220 hours, depending on your brightness settings. But while there are tons of things to love about this sight, it’s not perfect.
First, we wish the highest brightness setting was a bit brighter. Second, this sight doesn’t come with any sort of warranty. But when you consider the price and performance, there is still a ton to love.
When you’re looking for the best red dot sights for your Ruger Mark IV for the money, you can’t overlook the Feyachi Reflex Red Sight. It’s an extremely affordable option that allows you to cycle through four different reticle styles and two different reticle colors, giving you a grand total of eight different options to choose from.
It’s easy to mount on your Ruger Mark IV, and it’s even easier to sight in and use. However, it is a budget sight, which is why it only comes with five different brightness settings and doesn’t have a warranty. But for the price, you’re not going to beat it.
There’s no doubt that the Burris Fastfire III red dot sight is on the more expensive side. But it’s a top-notch sight that easily justifies the cost. For starters, it comes with a lifetime warranty, so you’ll never have to spend another cent on a sight.
You can also make all windage and elevation adjustments without any tools, allowing you to make quick adjustments in the field. Best of all, this sight comes with an automatic brightness sensor that optimizes performance and battery life without needing you to do a thing.
Finally, whether you’re looking for quick target acquisition or precision, Burris has an option for you. It has a Fastfire III with a 3 MOA red dot sight and a Fastfire III with an 8 MOA red dot sight. All you need to do is pick your favorite!
The AT3 Tactical ARO Micro Red Dot Sight is an excellent choice for your Ruger Mark IV. It comes with a lifetime warranty, so you’ll never have to worry about spending more money on a new sight.
Additionally, this sight has two different mounting options, which allow you to perfectly mount your sight to your Ruger. Even better, this sight has an extremely long-lasting battery life — it can last up to 50,000 hours on the lowest settings! But even on medium brightness, the batteries can last for 5,000 hours of use, so it’s not like you’ll be replacing them any time soon.
The downsides of this sight are the price and the limited brightness settings. There are only six settings to choose from, making it challenging to find the perfect brightness for your conditions.
The MA3TY Reflex Micro Red Dot Sight is an intriguing choice for your Ruger Mark IV. On the one hand, it has automatic brightness sensors. This is a huge perk that allows you to conserve your battery life and always have the optimal brightness on your reticle.
However, there are only five brightness levels that it can cycle through, and when you need to change the batteries, you have to remove the entire mount, which is extremely inconvenient. The 3 MOA red dot size is an excellent combination of precision and size, but the sight doesn’t come with a warranty.
All in all, there are plenty of things to love about this sight, but MA3TY could do better.
The E.T. Dragon Red Dot Sight is a decent sight for your Ruger Mark IV. The 2 MOA red dot reticle is excellent for precision shots, but its smaller size can slow down target acquisition a bit. Moreover, there are only four brightness settings to choose from, and it’s on the more expensive side for what you’re getting.
However, there are things to love about this sight. For starters, the maximum brightness setting is incredibly bright and easy to use even during daylight hours. The optics themselves are crisp and sharp. But in the end, there are better options at this price point.
Whether you’re new to red dot sights or just want to learn a little more, you’ve come to the right place. We developed this comprehensive guide for novices and experienced shooters alike to know what they need to look at when selecting a red dot sight for their Ruger Mark IV.
When you’re looking for a clear upgrade to your iron sights on your Ruger, look no further than a red dot sight. Red dot sights offer numerous upgrades over iron sights, and they don’t have any drawbacks.
For starters, these sights offer unlimited eye relief, which is a huge perk compared to traditional scopes. Red dot sights also provide faster target acquisition than iron sights and allow you to accurately shoot from non-conventional shooting positions.
This is a huge advantage if you’re shooting in tactical situations, where you won’t always have the luxury of having perfect form when taking your shot.
Finally, unlike traditional scopes that limit your field of view, red dot sights don’t have any impact on your field of view. You can line up your shot with both eyes open and see the entire situation. So, if you’re ready to upgrade your iron sight, a red dot sight is an outstanding choice.
When you’re selecting a red dot sight, this is one of the most important questions that you need to answer, and it all comes down to how far away your target is going to be and how precise you need to be.
That’s because while a larger MOA red dot sight is easier to see and line up, if you’re looking for a precise shot on a smaller target, a larger MOA size can blot out the entire target.
But if you’re using your Ruger for home defense or other short-range applications, a larger MOA size can be extremely beneficial. We recommend an 8 MOA red dot size for close range and home defense applications, while for precision shots, we recommend a 2 MOA red dot size.
It’s up to you to decide what you want to use your Ruger for and get a red dot sight that matches your needs. If you’re unsure what you need or plan to use your Ruger in multiple different settings, a 3 MOA red dot size is an excellent combination of both target acquisition speed and precision.
It doesn’t matter what sight you end up getting. If you don’t take the time to sight it in at the range, you’re never going to hit your target. The good news is that sighting in your sight can be easy if you take your time and know what you’re doing.
If you’ve sighted in a rifle before, the process to sight in a pistol isn’t any different; you just need to sight it in at a closer distance. We recommend sighting in your pistol at 25 yards for a few reasons. First and foremost, it’s a good distance that is extremely useful in a wide array of applications.
Second, it’s extremely easy to make and track MOA adjustments at this distance. MOA adjustments equate to a 1-inch adjustment at 100 yards, so when you’re making adjustments at 25 yards, you’re going to notice more of a change. But by sticking with 25 yards, you know that each adjustment will go four times as far as it would at 100 yards.
So, instead of each MOA equating to 1 inch, each MOA equates to 4 inches. By sticking with 25 yards, it’s easy to make the necessary adjustments.
When you’re finding a sight for your Ruger Mark IV, you need to ensure that you can mount it. The good news is that Ruger has an optional Picatinny rail mounting system, and if you have it, you can mount any of the red dot sights on the list.
If you don’t have that mounting rail, you have two options. You can either purchase that mounting rail or find an aftermarket option to mount your new optics. Without a mounting system, you will not be able to mount any aftermarket optics to your Ruger Mark IV.
Just keep in mind that the Picatinny rails, weaver rails, and dovetail rails are the most common, which means you’ll have more options when it comes to aftermarket optics.
Unlike traditional scopes that struggle in low-light situations but excel on extremely bright days, red dot sights excel in low-light conditions but struggle when there’s too much light. That’s where brightness settings come in.
By adding more brightness settings, you can crank up the power when you need to see your red dot on bright days, but you can power it down in dim conditions to save your battery life. But using the right amount of power is about more than just saving battery usage.
If you’re using too much power and your red dot reticle is far too bright for the conditions, it will actually look blurry. This can make it challenging to make your shot, which is why having it set up for the correct setting is critical.
It’s also why having a sight that auto-adjusts for you is a huge perk. This way, if you’re lining up a shot inside where it’s dark but need to head outside where it’s bright, you won’t have to change the settings to make your shot.
At the very least, you want a sight with plenty of brightness settings to allow you to get a clear and bright reticle.
When you’re looking at purchasing a new red dot sight, take a look at the warranty. While the products that offer a lifetime warranty undoubtedly cost more, you won’t have to worry about replacing them down the road.
So, do you want to spend more now or later? Because while you can save money on sights that don’t offer a lifetime warranty, chances are that you’ll be replacing them down the road, which will end up costing you more in the long run.
If you can afford a product with a lifetime warranty now, consider investing in a high-quality optic.
When you’re picking out a red dot sight, the last thing that you want is to never have it working because you constantly need to replace the batteries. While using the appropriate brightness settings for the situation is a great way to extend your battery life, it’s even better when you have a sight that doesn’t use a ton of power.
That’s where an option like the AT3 Tactical ARO Micro Red Dot sight excels. With a 50,000-hour battery life, you won’t have to worry about spending a ton of money on batteries or have to deal with the frustration of a sight that won’t turn on when you need it to.
Finding the perfect red dot sight for your Ruger Mark IV doesn’t need to be a complicated process. No matter what you’re looking for, you can’t go wrong with the Feyachi RDSD-25 red dot sight while you’re still figuring things out. It’s a top-notch sight available for a great price, and you won’t be disappointed.
However, if you’re looking to save a little more money, the Feyachi Reflex Red Sight is an extremely affordable option that you can get without breaking the bank.
But if you’re not sold on either of those, check the reviews again — we’re confident that the perfect red dot sight for your Ruger Mark IV is there.
