Bushnell Optics TRS-25 Hirise 1x25mm Red Dot Riflescope with Riser Block, Matte Black
Blazing Target Acquisition. Peak Accuracy.
There’s nothing like a red dot for fast target acquisition and accuracy in dim conditions, and no one makes red dots like Bushnell. The TRS-25 1×25 red dot is engineered with Amber-Bright optics to help you quickly distinguish between a brown tree and a brown critter. Thanks to the scope’s multicoated optics, hunters will have no problem seeing their target in low-light conditions. Other features include a 100-percent waterproof/fogproof/shockproof construction, a dry-nitrogen-filled housing, and a CR2032 battery.
About the Sight:
This sight can be easily used with both eyes open (eye relief is unlimited), increasing the shooter’s awareness of the surrounding environment and providing faster target acquisition. There is no need for centering, due to the parallax free design in which the dot follows the movement of the user’s eye while remaining fixed on the target. The TRS-25 delivers full size performance in a sight with reduced size and low power consumption.
Mounting the Sight:
The TRS-25 sight mounts easily on any Weaver style or Picatinny rail. An Allen style cross screw is used to secure the sight to the rail, and the clamping system provides adequate strength to keep it securely mounted. Once resistance is felt when tightening the screw it should be rotated no more than additional turn (over-tightening the screw may strip the threads).
About Red Dot Lens Positioning:
All red dot sights have an objective lens at the front of the unit that is spherical in shape. However, unlike a conventional riflescope, the objective lens in a red dot sight is positioned off axis and appears to be tilted when looking at the sight. This angle of the front lens allows the light generated by the battery powered LED light source inside the unit to be reflected back into the sight. The reflected light becomes the “dot” or aiming reference that the user sees when a red dot sight is switched on. This engineered “bending” of light is what makes today’s red-dot sights so popular and easy to use. Adhesive is used on the inside of the sight to secure the LED to the inside of the tube. By design, the led package intrudes slightly on the field of view.
About the Red Dot Reticle:
The TRS-25 utilizes a crisp, sharp red dot reticle. A control knob is used to adjust the red dot setting. A certain amount of resistance is designed into the control knob to ensure that the sight is not inadvertently turned on. The red dot may appear blurry if the dot intensity is set too high for the ambient light conditions. This is most likely to occur indoors with artificial, fluorescent lighting. The illumination control knob should only be set at the highest settings for use in bright ambient light conditions; for example, outdoors on a sunny day. An illumination setting that is too high for ambient light conditions typically results in a dot that appears distorted and non-concentric. For best results, increase the red dot setting until the scope gives the user an aiming reference that is perceptible but not glaring.
Installing the Sight with Hi-Rise Block
The AR731306 versions of the TRS-25 are supplied with a “Hi-Rise” mounting block that can be used to position the sight at the correct height for optimum performance on an AR-15 style rifle with a flat top receiver.
In order to use the riser block, first install the sight onto the hi-rise block. Ensure that the sight is correctly positioned and that the shaft fits into a groove on the block. To make sure that the shaft is firmly tightened, screw the shaft clockwise until a light resistance can be encountered. After that, screw another 1/4 to 1/2 turn. WARNING! Do not over tighten.
Once the sight is installed on the Hi-Rise block, the entire assembly can be mounted on the weapon. First, loosen the mounting screw so that the clamp will fit over the tapered side of the firearm’s Picatinny or Weaver rail. Ensure that the tapered clamp on the riser is oriented with the chamfered (beveled) end of the clamp at the top. Ensure that the riser’s cross screw with nut is tightened to clamp it firmly to the weapon’s rail. Turn the large nut on the riser block to turn with a coin, screwdriver or ” wrench. WARNING! Do not over tighten.

Rifle Glass Details
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnifying the target using a set of lenses inside the scope. The scope’s positioning can be adapted for the consideration of varied ecological elements like wind speed and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based upon the sight picture you are seeing using the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes and optics have about 11 parts which are located internally and externally on the scope. These parts include the rifle scope’s body, lenses, elevation dials, objective focus rings, and other elements. Learn about the eleven parts of rifle scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the best type of rifle optic is based on what type of shooting you plan on doing.
First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the amount of zoom being used. The result is that the reticle measurements are the same at the amplified range as they are at the non amplified range. One tick on a mil-dot reticle at one hundred yards with no “zoom” is still the same tick at 100 yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where calculations are minor
- Experienced shooters who have an idea for their target “hold over” and also “lead” correlations for their rifles
- Shooters who do not mind the reticle is enlarged and requires more visual eyesight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane glass (SFP) include the reticle behind the zoom lens. This induces the reticle to stay at the exact same size in relation to the amount of zoom being used. The effect is that the reticle measurements adapt based on the magnification used to shoot over lengthier distances given that the reticle markings present different increments which can vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These kinds of optics are beneficial for:
- Long distance types of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots occur within much shorter spaces and ranges
- Shooters who like a clearer optic picture with less room taken up by the bigger FFP reticle
Zoom for Rifle Glass
The level of scope magnification you need on your glass depends upon the sort of shooting you choose to do. Practically every style of rifle optic offers some level of zoom. The quantity of magnification a scope supplies is determined by the dimension, thickness, and curves of the lenses inside of the rifle scope. The magnification level of the optic is the “power” of the glass. This indicates what the shooter is looking at through the scope is amplified times the power element of what can typically be seen by human eyes.
Single Power Lens Glass
A single power rifle scope and optic comes with a magnification number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this type of scope can not change given that it is fixed.
Variable Power Lens Rifle Optics
Variable power rifle scopes can be modified between magnified levels. The power modification is handled by making use of the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Scope Power and Ranges
Here are some advised scope powers and the ranges where they could be successfully used. Bear in mind that higher magnification optics will not be as efficient as lower magnification level glass since excessive magnification can be a negative thing in certain situations. The same idea applies to longer distances where the shooter needs adequate power to see precisely where to best aim the rifle.
Details on Lens Finish
All modern rifle glass lenses are layered. Lens covering is an essential element of a shooting platform when considering high end rifle optics and scope systems.
HD Versus ED Lenses
Some glass companies also use “HD” or high-definition glass coverings that make the most of various procedures, chemical applications, polarizations, and aspects to enhance different color ranges and viewable target definition through lenses. This high-definition finishing is normally used with greater density lens glass which drops light’s opportunity to refract through the lens glass. Some scope suppliers use “HD” to describe “ED” signifying extra-low dispersion glass. ED deals with how colors are represented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration can be obvious around things with hard edges and shapes as light hits the object from particular angles.
About Single Coating Versus Multi-Coating
Different optic lenses can likewise have different finishings used to them. All lenses generally have at least some type of treatment or finishing applied to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has multiple treatments applied to the surfaces. If a lens receives numerous treatments, it can prove that a manufacturer is taking several actions to combat various natural factors like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finish. This also doesn’t necessarily indicate the multi-coated lens will perform much better than a single covered lens. Being “better” hinges on the maker’s lens treatment solutions and the quality of products used in constructing the rifle glass.
Hydrophobic Lens Finishes
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Options for Installing Glass on Firearms
Mounting approaches for scopes are available in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use throw levers which allow rifle shooters to rapidly mount and dismount the glass.
Rifle Scope Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long range accuracy shooting. This type of scope install is great for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, a number of scopes can also be switched out in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect firmly to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while retaining accuracy. These types of mounts are useful and beneficial for shooting platforms which are transferred a lot, to remove the scope glass from the rifle for protection, or for aiming systems which are adopted in between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your costly optic by bringing about fogging and creating residue inside of the scope tube. Many scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
What to Know About Optic Tube Gas Purging
Another element of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Since this area is already taken up by the gas, the scope is less influenced by temperature alterations and pressure distinctions from the external environment which could possibly permit water vapor to leak in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to seek out.
