Bushnell TRS 25 Red Dot Sight

Red dot sights (also referred to as red dot optics) have been around for quite some time. Though it was thought that the first red dot optic became available in 1975 by a Swedish optic company, the truth is, they were used on occasion throughout the second world war.

However, it is true that they grew in demand and hit the markets the hardest throughout the ’70s. Now, they are being used as much as ever over a wide variety of occasions.

Before we begin talking about the Bushnell TRS 25 Red Dot Sight, let’s talk a little about how these optics work, and how they differ from regular scopes.

How does a Red Dot Sight Work?

As the name would imply, there’s a red dot centered in the reticle where crosshairs would intersect on scopes. Red dot magnification is 1x, and don’t have built-in magnification multipliers as regular scopes do, which makes a sight and a scope two completely different animals.

Within the sight, there’s a spherical mirror. This mirror captures and reflects the light from a small, battery-operated LED. The light shines as a dot on the angled glass and produces a small dot centered on the reticle. Different brands and styles have various sizes of the dot.

Due to how the glass is angled and how the light is coming in from the far end of the sight, you can see the red dot from the eyepiece, but not from the opposite end. In other words, S.W.A.T.’s position won’t be compromised due to a red light illuminating what would otherwise be a shroud of darkness. The same is true as it would relate to hunters and game.

Minute of Angle (MOA)

Sights gage the size of the red dot on the ocular lens by Minute of Angle, or MOA. In other words, the smaller the MOA, the smaller the dot will be, the more challenging it will be to see it, but the more accurate it’ll be. A sight with 1 MOA will be the equivalent of a one-inch diameter around the center of your target at 100 yards. The larger the MOA number, the larger the dot and the less accurate the sight will be at range. The suggested for mid to long-range is 2 MOA. Recommended for close quarters is typically 4-5.

Why Use a Red Dot Sight?

Being a favorite among people new to shooting, red dot sights (which are sometimes green) make target location quick and is easy on the eyes. These are two reasons why such sights are used on weaponry meant for close quarter combat, or mid-range targeting.

A Red Dot sight is meant to be used at a close to moderate range and doesn’t zoom in on a target. It will improve your aim, but won’t enlarge the mark in a way that would make precision to be more significant as a scope would. So, keep this in mind when deciding whether or not you’d rather have a red dot sight or a scope.Pistol Scope

The red dot comes in a variety of different shapes and sizes. Not having to be concerned with size due to lack of scope-like innards, models are available to fit on a wide range of weaponry- handguns as well as rifles. Over the years, as technology has allowed us to make many things smaller, some styles of small Red Dots sprung into existence, making it easier to fashion these to smaller weapons.

Now, let’s have a look at a sight manufactured by Bushnell.

Bushnell TRS 25 Red Dot Sight – From Handguns to Shotguns

Buy it on Amazon.

Unlimited Eye Relief
This unit has an unlimited eye relief, meaning that you can have your arms extended (such as you would with a handgun), and still see the sight without a problem. The red-lit dot can be adjusted via its eleven lighting settings to accommodate any lighting conditions.

3 MOA Dot
The TRS 25’s dot is 3 MOA, which is in that sweet spot between mid to long-range and close range. A decent general size.

Weaver Rail System
To ensure that these sights fit on any rail system, they decided to make the TRS 25’s using the Weaver compatible rail system. This was a wise Airsoft paint ball gamesdecision since Picatinny rail accessories won’t fit a Weaver rail, but Weaver railed accessories will fit both Weaver and Picatinny rail systems.

Tough Exterior
The outer shell of the sight is waterproof even to the point of submersion. The O Ring system installed keeps all of the internal workings safe from any moisture that may attempt to creep in.

The casing is also shock resistant, which means that all of the bouncing, bumps, bangs, or recoil, won’t affect the sight. It’s built to withstand rigorous conditions and harsh handling that would come with being out in the field, in the woods, or on the chase.

Fog Proof
This sight will not fog up due to the Nitrogen purged & filled fog proofing, that has been incorporated within the case. Just as the sight was built to be waterproof, the same standard keeps the nitrogen inside the shell, enabling the nitrogen to keep the lens fog-free for unhampered use in moist conditions.

Conclusion

There are a few things that you’ll have to hash out before you decide to pick up any red dot sight. The first thing to figure out should be whether or not you want a sight, rather than a scope. Hopefully, this page helped you out with that.

Next, what is your intention behind wanting to use the sight- close range or mid-far range? This should determine the size dot you’d need. However, if you’re looking for the most versatile, with the ability to sight in a target decently in all spectrums, the 3 MOA of the TRS 25 will be the best sight for you.
