When you’re looking for iron sights that expertly combine price and performance, the Magpul Industries MBUS Generation II Sight is what you want. It has a spring-loaded flip-up design, comes with a lifetime warranty, and has a durable construction.
Our only problem with this sight is that Magpul used a ton of plastic instead of steel. While the plastic is incredibly durable, there’s no doubt that it’s a bit bulky. In the end, that’s how the company keeps the price down, but it’s definitely a factor that you need to consider if you’re going to be using this sight often.
If you’re looking for the best iron sights for an AR-15 for the money, you want the TACTICON 45 Degree Offset Flip Up Iron Sights. They’re extremely affordable, have a convenient offset design, and come with a lifetime warranty.
Even better, these sights come with all the adjusting and mounting hardware that you’ll need. However, they’re discount for a reason, so it can be difficult to adjust these sights, and they have a bulkier design that can make it difficult to see through them.
For the price, you’re not going to beat them, but you can certainly do better if you’re willing to spend a little more.
If you’re not worried about how much your new iron sight will cost, the Troy Industries HK Style Front and Rear Battle Sight is an outstanding choice. While it’s more on the expensive side of things, it does come with a lifetime warranty, so it’s the last iron sight that you’ll need to purchase for your AR-15.
The sight folds down and is extremely easy to use, features a low profile, and has an all-metal construction. However, keep in mind that this sight does not come with the necessary adjustment tools, so before you take it to the range, ensure that you have everything that you need.
An outstanding iron sight option for your AR-15 is the Magpul MBUS Pro Steel Sight Set. It’s definitely more expensive, but it comes with a lifetime warranty and is extremely easy to use. Magpul made this sight entirely from steel, giving it a slim and low-profile design that is great to use.
Even better, you can make both windage and elevation adjustments without any tools, which is a huge perk. Keep in mind that you’ll need to purchase tools to adjust the front sight separately, and you won’t be able to properly sight this in at the range without it.
If you’re looking for a durable and long-lasting straight-up iron sight, you could do far worse than this.
The Magpul MBUS Pro Offset Front and Rear Flip-Up Sights have great quality. They also come with a lifetime warranty and have a low-profile steel construction.
Even better, you can make both windage and elevation adjustments without any tools. However, keep in mind that it doesn’t come with front sight adjustment tools. That said, if you’re looking for a long-lasting 45-degree offset iron sight from a reliable brand, this is an outstanding choice.
Iron sights don’t always get the same amount of love as the fancier red dots and scopes, but it’s still important that you get the right ones to get the job done. That’s why we created this comprehensive buyer’s guide to walk you through everything that you need to know before and after you make a purchase.
This way, when you get your new sight, you’ll know exactly what you need to do and be able to get out to the range!
First, we need to make you aware of what you need to check for as soon as you receive your new iron sights. There’s a popular scam out there where users will purchase a knockoff sight on eBay before ordering the real one through Amazon. They then return the knockoff sight to Amazon, and the warehouse doesn’t always notice the difference. Finally, the knockoff sight gets sold as the real thing, which means the next customer gets ripped off.
The good news is that if you know what you’re looking for and spot the fake, Amazon is great at taking it back and sending you the real thing. But save yourself the headache, and research the product that you’re ordering before you make a purchase. This way, when it arrives, you can tell if it’s the genuine article or not.
If you opted for a sight that utilizes a metal construction, one of the best ways to tell if it’s fake is to ensure that it’s actually a metal design. Most fakes don’t opt for the more expensive metal construction, and it’s a telltale sign that the sight is a knockoff.
When you’re picking out the perfect iron sights for your AR-15, one of the most important decisions that you need to make is whether you want offset iron sights or a straight-up design. Offset iron sights sit angled on your AR-15, which is critical if you’re using a standard scope on top.
Having both options allows you to hit distant targets with your traditional scope without sacrificing your short-range ability. Keep in mind that learning to shoot from an offset iron sight does take a little extra practice, but having both an offset iron sight and a traditional scope gives you the best of both worlds.
If you’re looking for a straight-up sight, you won’t be able to use a traditional scope, but since these options feature a flip-up design, you can still use a red dot sight or a holographic sight. Having an iron sight on a weapon with one of these sights gives you a backup option in case your batteries die when you need your AR-15 the most.
Just because it’s an iron sight doesn’t mean you don’t need to take it to the range to sight it in. If you don’t take the time to do so, you’re not going to hit a thing when you go to use it.
Keep in mind that you’ll need an adjustment tool to sight in the front sights, and out of the options on this list, only the TACTICON 45 Degree Offset Flip Up Iron Sight comes with one. That means if you opt for a different sight, you’ll need to purchase the adjustment tool separately if you don’t already have one.
While the tool itself is easy to use, not having it when you head to the range can be incredibly frustrating because you won’t be able to sight in your iron sights without it.
Sighting in an iron sight isn’t any different from sighting in a different kind of scope or sight.
Just because you primarily use your iron sights for close-range targets doesn’t mean you don’t need to worry about elevation and windage adjustments. While it’s not as important, it’s still going to affect your shot.
So, if you need precision, opt for an iron sight that allows you to make toolless windage and elevation adjustments. While it might not seem like a big deal now, you’ll be grateful when you need to make tweaks at the range or in the field.
While the options on this list aren’t the lowest-priced out there, they all come with a lifetime warranty. While every company is going to promise that its product will last a long time, those with a lifetime warranty guarantee that they’ll last forever.
If they don’t, the company promises to fix it or replace it for you, keeping you from having to purchase the same product twice. So, while you might be spending more on these sights up front, they all save you money in the long run, which is why they’re a much better deal.
If you are looking to save a little money, go with the TACTICON 45 Degree Offset Flip Up Iron Sight. It’s not much more than the cheaper options without a warranty, and it’s still the last iron sight that you’ll need to purchase for your AR-15.
While it can seem overwhelming when you’re picking out the perfect iron sights for your AR-15, you can’t go wrong with the Magpul Industries MBUS Generation II Sight. It’s our top choice for a reason, and it’s surprisingly affordable.
However, if you’re looking to save more money, the TACTICON 45 Degree Offset Flip Up Iron Sight is available for a phenomenal price.
But if you’re not in love with either of those options, read through the reviews again. We’re confident that the perfect set of iron sights for your AR-15 is there.
