Holosun Technologies have always been known for manufacturing red dot sights for primary arms, until recently when they decided to go into the manufacturing of optics.

They used the design of the HS403A to make the HOLOSUN HS403G Paralow and both devices look very similar with the main difference being that the location of the battery housing has been changed to the right side of the optic which has enhanced battery replacement.

The mount now has full T1 compatibility and any T1/H1 can be used for this sight. They have also updated the turret adjustment mechanism and it is now just 3mm higher than the HS403A which has resulted in easier adjustment with gloved hands.

Its 2MOA red dot has 12 brightness settings, of which its brightest settings can be easily seen even in the most sun-filled days.

It has a very strong battery life of 50,000 hours which could amount to 5 years of usage and coupled with its 8-hour automatic shut off, you need not worry about it when you drop it in your safe without shutting it off. It has automatic turn on too and it turns itself on at the slightest tap.

The control of the push button feels good but has a soft rubber texture which seems to attract dust. The turrets have great clicks and the optic doesn’t seem to fail in maintaining zero. Although the aim point has a two-prong key and losing the caps could cause a problem.

This device is really a top product and we totally recommend it. It is also a good value for money and we’re sure nobody will regret the decision to purchase it.

What Is A Parallax-Free Red Dot Sight?

What is a red dot light first of all? A red dot sight is a non-magnifying reflex sight for firearms that provides an aim point for the shooter in the form of a red dot.

Parallax-free red dot sights are quite complicated to explain, but to put it simply, when a shooter is aiming at something, the red dot makes an adjustment for angular parallax without the shooter moving his rifle at all.

A parallax-free red dot makes it easier to aim at greater ranges and still be able to hit the target without too much effort. Put on a red dot and look through it, adjust your head afterward without moving your rifle.

You will see the dot moving around in the optic and that’s because of physics and math. Although the dot has moved, your rifle hasn’t moved, and that means the point of impact remains the same, and that’s because the red dot has made a correction for angular parallax.

Why You Need a Parallax-Free Red Dot Sight

Razor Red Dot

Parallax is the main reason red dots can be essential to shotgun users. Parallax is the shift in the position of a stationary target when using a scope to keep it on lock, then you suddenly move your head a little and this results in the object appearing to be indifferent position.

The speedometer in your car is a practical example of this. It is easy to see the precise speed at which you are traveling if you are looking at the speedometer from the driver’s seat.

Now, still traveling at the same speed, ask someone sitting in the passenger’s seat right beside you to look at the speedometer from his angle, and you will see the person will see another thing entirely to what you saw. The contrast in viewpoint is a result of parallax. For shotgun users, this is exactly why the use of parallax-free red dot is very crucial.

When using a parallax-free red dot, it eliminates the possibility of shooting off target as a result of parallax, as it provides an aim point for the user in the form of a red dot.

You may have minor parallax issues when aiming from a longer distance like 75 yards or more but you can also fix this by getting high-end red dots, as they have features that deal with this issue.

Features to Consider Prior to Purchase

Razor Red Dot

When you decide to purchase the red dot sight, there are some important factors you should put into consideration when buying, such as your needs, the size of the reticle, battery life, and warranty. It’s important to consider these factors before making your final decision so you wouldn’t regret anything in the end.

Your Needs

Before you purchase any product, you should, first of all, ensure that it would suit your needs. This is very important as there are lots of times that people would make a decision to buy something, maybe because it’s a trend or something like that, then they would later realize that they didn’t need it in the first place.

Another factor relating to this is the issue of budget. You shouldn’t opt for the costliest product just because you believe expensive things often have the best qualities.

This notion might be wrong sometimes and there are actually some expensive products that wouldn’t really be a value for money after all. However, a cheaper product may not have the features that you want, so you should make witty decisions.

Battery Life

One of the first and important things you put into consideration when purchasing a device should, of course, be its source of power. It’s very necessary to choose a device with strong battery life as you wouldn’t want your device to be down at the time you need it most.


Only a manufacturer that has total trust in their products offers a warranty, as manufacturers that have produced inferior products intentionally would never dare to do this, as it would result in a huge loss for them in the long run.

So, ensure you check the condition of the warranty and make finding out about the brand’s care for a customer just in case you have one or two issues with the product.

Final Thoughts

Humans are visual creatures. Seeing something with our own two eyes gives it credibility. Especially when dealing with something unknown or even unknowable, laying eyes on it gives us some sort of comfort. Of course, there are many options to select from, and different makes and models.

But with the products listed above, we are very sure that you will consider well the best choice to make, thereby without further delay, simply go for the device that is suitable for your needs perfectly. We’d love to hear which device you ended up going to within the comments section below.
