In contrast, the C4 Sight System creates a perfectly concentric circle-within-circle sight picture that is drastically more intuitive than traditional iron sights, allows the shooter to see the target not cover it, enables faster sight acquisition, reduces the effect of parallax, and gives the ability to consistently shoot accurately out to 600 yards and beyond.

How to Zero Flip Up Sights? 🤔
📢 Zeroing Flip Up Sights is a crucial step in ensuring accuracy when using them. 👣 Here are the general steps for zeroing:
1️⃣ Choose a shooting distance:
- ➜ Determine the distance you will be shooting and set up the target at that range.
2️⃣ Set up your firearm:
- ➜ Ensure that the firearm is properly mounted in a stable shooting rest or position. This will help eliminate human error and allow you to accurately adjust your sights.
3️⃣ Adjust windage:
- ➜ Using the windage adjustment on the sight, adjust the point of impact left or right until it lines up with your point of aim.
4️⃣ Adjust elevation:
- ➜ Using the elevation adjustment on the sight, adjust the point of impact up or down until it lines up with your point of aim.
5️⃣ Check your zero:
- ➜ Take a few shots to confirm that the point of impact is lining up with the point of aim. If necessary, make additional adjustments until you achieve the desired zero.
⚠️ It’s important to note that zeroing will require some trial and error, and it may take a few adjustments to achieve the desired result. 💠 It’s also a good idea to periodically check your zero, as it can be affected by changes in ammunition, weather conditions, or other factors.

The MBUS Gen2s is a reliable and reasonably priced option that has never failed me in maintaining zero. The only drawback I’ve encountered is that the ambi front sight latches may obstruct certain offset light mounts. However, more expensive metal BUS alternatives like the MBUS Pros do not pose this issue.
Can Flip Up Sights be used with any firearm?
🔔 Flip Up Sights are designed to be used with firearms that have a Picatinny or Weaver rail system. 🔵 Most modern rifles and carbines have this type of rail system, but it’s important to check the specifications of your firearm before purchasing Flip Up Sights.
In my experience, I’ve utilized various backup iron sights such as the Magpul Gen2, Magpul Pros, generic Diamondhead 45-degree offsets, and UTG Pros. From my observation, all of them have functioned similarly.
The determining factor should be how frequently you intend to use your firearm and if you require a robust, well-tested option. In this case, it might be worth investing in more expensive options. However, if you only need a backup sight for “just in case,” you can save money and put it towards a high-quality optic.
Personally, I’ve been satisfied with all the options I’ve used. However, I ultimately chose the UTG Pros because of their slim profile and compatibility with my intended use.
I have experience using both the YHM and Midwest Industries gas block flipped up front sights, and both have demonstrated exceptional durability, retaining their zero even under significant stress. In previous years, I have also utilized both an mbus and a UTG flip-up sight. While I appreciate both options, I personally favor the UTG as it is made of metal, and changing the aperture size is more effortless. Additionally, the UTG sight can lay down flush regardless of the aperture size chosen, a feature that the mbus does not possess.
Hey, so I built my first AR, and it didn’t come with any sights or anything. I got a cheap $60 red dot, but it was constantly running out of juice. So, I’m thinking of going with iron sights for now because they can’t be that expensive, can they? Any recommendations for good iron sights for my AR?
I’d say go for the Midwest Industries steel flip-up iron sights. They’re top-notch in terms of quality, they’re compact, and they won’t break the bank.
MBUS Pros is a solid choice. Alternatively, if you’re not running a red dot, fixed sights might be a better option. For instance, you could opt for a DD fixed front sight and a detachable carry handle rear sight. Another brand to consider is Scalarworks, which produces high-quality fixed sights.
I’ve tried out the Magpul mbus pro sights and they’re pretty sweet as flip-up sights. But personally, I’m a big fan of the Scalarworks fixed front sight paired with the Magpul pro rear sight. It’s a killer combo!
If you’re willing to spend a pretty penny, Knights Armament has some seriously awesome sights. They’re definitely on the pricey side, but they’re worth it if you’re looking for top-tier quality.
I gotta say, the Magpul pro flip-up sights are pretty awesome. I’ve got a set on my AR10 right now as I save up for an ACOG. I’ve taken it out to 200 yards and haven’t had any problems whatsoever.
I grabbed a set of Magpul pro sights for my S&W M&P 15-22 Magpul edition, which I use as a training gun. Gotta say, I’m a fan. They’re easy to see and adjust, and they didn’t cost me an arm and a leg like my Knight’s Armament SR-15 sights.
I’ve got a Bushnell TR-25 mounted up too, and they co-witness perfectly. I’m using a riser to get the Bushnell in the right spot, so the Magpul sights sit in the bottom 1/3 of my sight picture. But it works great.
The coolest thing about the Magpul sights is that I can flip them down when I’m using the red dot, and pop them right back up if I need to go back to irons.
So I just finished building my first AR, and I’ve got a Vortex Strike Fire 2 and a Vortex 3x magnifier on it. The thing is, my magnifier sits pretty far back, so I don’t have room for a rear backup sight.
I’m thinking about just putting a flip-up front sight on it and calling it good. I figure I could at least be somewhat accurate at 20 yards or so. But I’m not sure, and I was wondering if anyone has any experience with a setup like this, or if they have any recommendations for what I should do.
Congratulations on finishing your first AR build!😉 As for your question, having just a flip-up front sight can work fine for short-range shooting, but it’s not ideal for more precision shooting at longer distances.
1️⃣ If you’re comfortable with the idea of not having a rear backup sight, you could try using your magnifier in conjunction with your red dot sight to increase your accuracy at longer ranges. However, keep in mind that this will require a lot of practice and adjustment to get used to.
2️⃣ Another option could be to look for a different magnifier that doesn’t sit as far back, allowing you to have a rear backup sight as well.
3️⃣ You could also consider using a different type of backup sight, such as a 45-degree offset sight that can sit alongside your magnifier.
📢 Ultimately, the best solution will depend on your personal preferences and shooting style, so it may take some experimentation to find the setup that works best for you.
