Buyer’s guide

Bushnell TRS-25 First Impression

The Bushnell TRS-25 is a red dot sight that is often compared to the more popular Aimpoint Micro. It is a very popular option for those looking for a quality red dot sight without breaking the bank. The TRS-25 has been around for quite awhile and has proven to be a reliable option.

Bushnell TRS-25 First Impression

One of the first things you will notice about the TRS-25 is its size. It is very small and compact which makes it great for mounting on pistols or AR15s. It is also very light weight which makes it easy to carry around. The body of the scope is made out of aluminum which gives it a solid feel. [4]

Bushnell TRS-25 Features

The Bushnell TRS-25 is a budget red dot sight that has been on the market for a while now. It is popular among shooters due to its low price and decent performance.

Red Dot Reticle

The TRS-25 features a red dot sight with a three MOA reticle.

To see the red dot, you will need to look through the scope with both eyes open.

The red dot is visible in all lighting conditions, making it ideal for low light situations.

Reticle Options

The Bushnell TRS-25 red dot sight has a three MOA black dot reticle with 11 different brightness settings. This makes it one of the most versatile sights on the market, as it can be used in a variety of lighting conditions.

11 Brightness Setting overview

The TRS-25 has 11 brightness settings. This allows you to set the scope’s reticle to match the environment and your preferences. The lower the setting, the dimmer the reticle will be. The higher the setting, the brighter it will be.

You can adjust the scope’s brightness by turning the knob at the top of the scope.

The adjustment range is from 0 (dim) to 11 (bright).

Here is a quick overview of some of these settings:

0 = Dim

Setting 0 is the lowest brightness setting and is best used in very low light conditions or when you don’t want the reticle to be visible.

It’s also a good idea to use this setting when you’re first setting up the scope as it’s easier to see the crosshairs against a darker background.

Once you’ve got the scope mounted and sighted in, you can experiment with different brightness settings to see what works best for you.

5 = Medium

Setting five is a good all-purpose setting. It’s bright enough to see in most lighting conditions but not so bright that it will wash out the target.

This is a good setting to start with and then adjust up or down as needed.

8 = High

The reticle will be very visible at this setting, making it easy to acquire your target. However, it can be harder to see faint targets against a bright background.

11 = Bright

The highest brightness setting, eleven, is best used in very bright conditions or when you need the reticle to be highly visible.

11 = Bright

Keep in mind that at this setting, the battery will drain more quickly so it’s not ideal for extended use. But it can be helpful when you’re trying to take a shot in direct sunlight. [2]

Dot Adjustment

The TRS-25 comes with a red dot sight that is adjustable for both windage and elevation. To adjust the dot, simply use the included Allen wrench to turn the screws on the top and side of the sight. For windage adjustment, turn the screw on the top of the sight. For elevation adjustment, turn the screw on the side of the sight.

Keep in mind that each click of the adjustment screws will move the dot by approximately one MOA (minute of angle). One MOA is equal to about one inch at 100 yards, so make small adjustments until you get the dot where you want it.

Power Source

The Bushnell TRS-25 is a red dot sight that uses a CR2032 battery. This type of battery is very common and can be found at most stores that sell batteries. The Bushnell TRS-25 has a stated battery life of up to 250 hours, which is pretty good for a red dot sight.

However, many users have reported that the scope only lasts for about 100 hours before needing to be replaced. This isn’t terrible, but it’s something to keep in mind if you’re planning on using the scope extensively.

One way to help extend the battery life is to use the scope’s “auto-off” feature. This will turn off the scope after a period of inactivity, which can help conserve battery power.

Another way to save on batteries is to buy a rechargeable CR2032 battery. These can be found online or at some stores that sell electronic accessories. Rechargeable batteries can be used over and over again, so you don’t have to keep buying new ones all the time.

If you plan on using the Bushnell TRS-25 extensively, it might be worth investing in a rechargeable battery.
Otherwise, you’ll probably be fine just using regular CR2032 batteries.

Manual for Bushnell TRS-25

If you want to get the most out of your Bushnell TRS-25, it is important to consult the manual. This will help you understand how the scope works and what features are available. The manual also includes maintenance information and troubleshooting tips.

Setup and Operation

Installing the battery

The first thing you need to do is unscrew the battery cap, which is located on the left side of the scope. Next, insert the CR2032 battery into the compartment and make sure that the positive end is facing up. Once the battery is in place, screw the cap back on tightly.

To turn on your Bushnell TRS-25 scope, simply press and hold down the power button for about two seconds. You will see a red dot appear in the center of the lens; this is your aiming point. To adjust for windage and elevation, use the screws located on either side of the scope.

If at any time you need to turn off your scope, just press and hold down the power button for about two seconds. The red dot will disappear, indicating that the scope is now off.

Mounting Your TRS-25

Now that the scope is powered, you need to mount it onto your gun. If you’re using a Picatinny or Weaver rail, this is easy enough to do. Just loosen the screws on the side of the scope, slide it onto the rail, and then tighten the screws back down. The scope should be securely mounted so that it doesn’t move around when you’re shooting.

If your gun doesn’t have a Picatinny or Weaver rail, you’ll need to use rings to mount the scope. There are many different sizes of rings available, so make sure you get the right ones for your particular gun and scope. Once you have the rings, just follow the instructions that came with them to install them onto your gun.

Zeroing Your TRS-25

If you’re a first time user of the TRS-25, or any red dot scope for that matter, you may be wondering how on earth you’re supposed to zero it. Zeroing simply means adjusting the windage and elevation dials on your scope so that the red dot is lined up with where your bullet will impact at a given distance.

There are a few different ways that people like to zero their scopes, but we think the following method is the simplest and most effective way to do it. First, find a comfortable shooting position and set up a target at about 25 yards away. Next, turn on your red dot sight and take aim at the center of the target.

Zeroing Your TRS-25

Now, fire a few shots and see where they land in relation to the red dot. If your shots are hitting low and to the left of the dot, you’ll need to adjust the windage and elevation dials accordingly. For each click that you make on either of these dials, the red dot will move about an inch at 100 yards.

Keep making adjustments until your shots are consistently hitting where you want them to, then move your target out to 50 or 100 yards and repeat the process until you’re confident that your scope is properly zeroed.

Operation Under Extreme Conditions

During your Bushnell TRS-25 operation, you may encounter different types of extreme conditions. For example, if you are in a cold area, the temperature can drop to -50 degrees Fahrenheit. If this happens, do not worry. The scope will still work properly. Just make sure to keep it clean and dry at all times.

In addition, you may also come across dusty or sandy environments. Again, don’t worry too much about it. The scope is designed to function in these types of conditions as well. Just be sure to keep it clean when you’re done using it.

Lastly, you may find yourself in a situation where there is high humidity. This is not an issue either.

The Bushnell TRS-25 is designed to work properly in humid conditions.
Just be sure to store it in a dry place when you’re not using it.

By following these simple tips, you can be sure that your Bushnell TRS-25 will function properly no matter what type of extreme condition you encounter.

Care & Maintenance

To keep your scope in optimal condition, it is important to practice proper maintenance. This means regularly cleaning the lens and making sure that there are no smudges or fingerprints.

It is also important to keep the body of the scope clean and free of dirt and debris.
In addition, it is a good idea to check the screws and bolts on the scope to make sure they are tight and not loose. If you follow these simple tips, your Bushnell TRS-25 will provide you with years of trouble-free service.

One of the most important things you can do to keep your scope in good working condition is to regularly clean the lens. A dirty lens will reduce the quality of your image and make it more difficult to see your target.

To clean the lens, you will need a soft, clean cloth and some lens cleaning solution. Simply apply a few drops of solution to the cloth and then gently wipe the lens in a circular motion. Once you have finished cleaning the lens, be sure to remove any excess solution with a clean, dry cloth.

Care & Maintenance

Another important tip for maintaining your Bushnell TRS-25 is to keep the body of the scope clean. Dirt and debris can build up on the body of the scope and eventually find their way into the lens, which will reduce the quality of your image.

To clean the body of the scope, you can use a soft, clean cloth and some mild soap and water. Simply wipe down the body of the scope with the cloth until it is free of dirt and debris. Once you have finished cleaning the body of the scope, be sure to dry it off with a clean, dry cloth.

Finally, it is important to check the screws and bolts on the scope to make sure they are tight and not loose. Loose screws and bolts can cause the scope to become misaligned, which will reduce the quality of your image.

To tighten the screws and bolts on the scope, you will need a screwdriver. Simply tighten the screws and bolts until they are snug, but be careful not to over tighten them.

By following these simple tips, you can ensure that your Bushnell TRS-25 will provide you with years of trouble-free service.


Why do I need a riser for my red dot?

If you’re looking to mount a red dot sight on your AR-15, you’ll need a riser. Risers are necessary to ensure that your red dot is at the correct height for co-witnessing with your iron sights. Co-witnessing is when both your red dot and iron sights are visible in the same sight picture. This is important because if your red dot fails, you can still use your iron sights to get accurate shots off.

There are a few different heights of risers available, so it’s important to choose the one that will put your red dot at the correct height for co-witnessing. The most common heights are 0.250″ and 0.500″.

Does Bushnell TRS-25 need a riser?

The Bushnell TRS-25 comes with a Picatinny/Weaver rail mount but no riser. If you have a standard AR-15, M16 or M1913 Picatinny rail, the TRS-25 will fit without issue. If you have a non-standard rail or want to use the TRS-25 on an AK, you’ll need to get a separate riser. Most users report that the TRS-25 works well with risers made by other manufacturers such as UTG.

How does Bushnell TRS-25 compare to similar scopes?

The Bushnell TRS-25 is very similar in specs and performance to other popular red dot sights such as the Vortex Sparc II, the Sig Sauer Romeo-MSR, and the Holosun HS503GU. All four scopes have red dot sights with a 25mm objective lens, unlimited eye relief, and are parallax free. The main difference between the TRS-25 and its competitors is price; at around $100, the TRS-25 is one of the most affordable red dot sights on the market.

Is the Bushnell TRS-25 parallax free?

The Bushnell TRS-25 is not parallax free. This means that at certain distances, the crosshairs will appear to move relative to the target. This can be an issue when trying to shoot accurately at long range.

To fix this, you can either use a higher power scope, or adjust the focus knob on the Bushnell TRS-25 until the crosshairs are in focus.

What is the eye relief on the Bushnell TRS-25?

The eye relief on the Bushnell TRS-25 is about three inches. This means that you will need to position your eye about three inches away from the eyepiece in order to see the full field of view.

If you have a scope with a longer eye relief, you will be able to position your eye further away from the eyepiece and still see the full field of view. This can be useful if you wear glasses or want to mount the scope further away from your eye.

What battery does Bushnell TRS-25 take?

The scope uses a CR2032 battery, which is a common type of button cell battery. You can find these batteries at most stores that sell electronic devices or batteries.

What magnifier works with Bushnell TRS-25?

The TRS-25 will work with any number of magnifiers, but we recommend the Bushnell AR Optics Magnifier. It’s a great way to get more out of your scope without breaking the bank.

Is it ok to use it on airguns?

The TRS-25 is a versatile scope that can be used on both airguns and firearms. It is important to note, however, that the scope is not designed for high-powered airguns. If you are using an airgun with a muzzle velocity of over 1200 feet per second, it is recommended that you use a different scope.

Can I use it in low light conditions?

Yes, the TRS-25 has good light gathering capabilities and can be used in low light conditions. However, it should be noted that the scope does not have an illuminated reticle. This means that you may have difficulty seeing the crosshairs in very low light conditions.

Does the Bushnell TRS scope turn off automatically?

Yes, the Bushnell TRS scope turns off automatically after being idle for a period of time. You can adjust the length of time before the scope shuts off in the menu settings.

How long is the warranty on the Bushnell TRS scope?

The Bushnell TRS scope has a limited lifetime warranty. For more information, please visit the Bushnell website.

Is the Bushnell TRS waterproof?

Yes, the Bushnell TRS is waterproof and fogproof. It can withstand being submerged in up to three feet of water for up to 30 minutes.
