Red Dot for AR15: Buying Guide
Red Dot for AR15: How do You Mount It on the Firearm?
It doesn’t matter if you’ve never mounted and zeroed in sight in your life. Because it’s not such a difficult task and you can easily do it by yourself. But before that happens, you must know two essential components. And they are the sight’s locking mechanism and rail.
Every AR15 is equipped with a tactical rail or a Picatinny. This acts as the anchor point that is used to attach various accessories. What it consists of is repeating ridges as well as slots. And it’s on these features that the locking system of accessories attaches itself to for a secure connection.
You don’t have to worry if your accessory is designed for Weaver rail instead of Picatinny rail. Because it will fit your AR15 nevertheless.
Picatinny vs Weaver Rail
The location for mounting a red dot holds great importance. You must choose a point that isn’t too forward or backward. This gives you an excellent aim. Despite knowing this, many shooters still tend to place the sight near the rear. You can do this with magnified optics because it comes with eye relief. But not with red dots as they have wide eye relief.
So you can place it a little further too, and you will still be able to focus. Putting a red dot near the rear of your AR15 will restrict the peripheral vision and field of view.
On the other hand, some shooters position the sight way too ahead than it should be. Such a placement does work in certain situations. But I would suggest otherwise as it might cause your sight to lose the zero faster.
This happens due to perpetual shifting when you’re shooting. And with such a position, you also tend to spot the sight slightly later once you raise your gun.
So the most preferred location for mounting the best red dot for AR15 is the top receiver’s forward portion. Once you’ve selected the correct spot, you can mount your sight. Some devices have an inbuilt rail system while some models are equipped with separate rails.
If you have the former, then position the rail correctly and use the screws to tighten it. And if you have the latter, then you need to first mount the rail on your weapon. Then comes the fitting of the sight. To ensure that you have a secure fit, tighten all the screws that the rail came with. But please don’t over-tighten them. That might cause damage to the sight.
Red Dot for AR15: What are Its Benefits?
The most significant advantage of using the best red dot for AR15 is related to performance and price. The thing about red dots is that they deliver maximum performance at the minimum price. What you should also understand is that an AR15 sight is comparatively safer than its holographic counterpart.
When using a sight equipped with holographic technology, your eyes are exposed to a high risk. If the lens of a holographic sight cracks, significant permanent eye damage can happen, because of the laser direct to the eye.
AR15 sights are constructed of aluminum alloy or just aluminum. And that’s great, but do you know why? Because these two materials are weight-optimized. But the primary benefit of using a red dot will always remain the same. The device is solely designed to help shooters acquire targets faster.
Red Dot for AR15: What Features to Take into Consideration?
Optics
When a sight is constructed with high-quality components and has a strong, solid construction, what does that mean? That the device is reliable and backed by a reliable manufacturer, right? And when this has been established, you don’t need to worry about the optics.
As far as optics are concerned, there is only one rule. The more you pay for an AR15 sight, the better the optics will be. Because an optic is the only expensive feature to build on a sight.
Now don’t go spending big bucks on buying the costliest AR15 sight. Instead, focus on what kind of performance the optic has to offer. And this depends on the different reasons why you want to use an optic in the first place.
Another feature that you must take into account in regards with optics is their ruggedness. Shooting involves major and minor impacts and recoil, right? At such times, the optic must do its best not to lose the zero point. And to achieve this, optics should provide maximum ruggedness and durability.
And the last characteristic of optics that you need to know is their capacity to acquire the target quickly. This is essential for defensive and tactical purposes or when you’re hunting at close range.
Design of the Sight
The thing about an AR15 is that it was intended to be a lightweight and compact rifle. So it won’t make any sense of you choose a sight with a large and heavy design. The red dot for AR15 is one that is as lightweight and compact as your rifle.
How to Zero Your AR-15 Red Dot Sight?
The final verdict
A red dot is a highly valuable device that is commonly used on rifles, pistols, and shotguns. It helps the shooter in achieving more accuracy and faster target acquisition. But when it comes to AR15, remember that it already is an accurate weapon.
So purchasing the best red dot for AR15 helps in quickly acquiring and firing upon your desired target. Keeping this mind, you should opt for the Ohuhu Red and Green Reflex Sight.
The Ohuhu Red and Green Reflex Sight have a tubeless design. And this model is equipped with a wide enough lens aperture. Such a reflex lens structure offers a large viewing field. What these features do is make the sight suitable for shooting moving targets.
The best part about the Ohuhu Red and Green Reflex Sight; it has an integrated mount. This is perfect for regular bases. So there’s no need for the shooter to re-zero when he or she is remounting the sight. And the last valuable thing that I would like to add is that the device is exceptionally shockproof and waterproof.
