Do you need a scope for hunting, competitive shooting, or maybe home-defense?

Competitive shooting; How far out is the first target? Or last? What is the maximum range of all targets, On average?
Home defense; If the owner is protecting a large parcel of land, a rifle scope may be needed. How large is the parcel at the farthest distance? Most home defense applications do not require a scope
Hunting is always an ideal reason for having a quality optic. What are you hunting? Are you in a tree stand looking down at a 50-yard whitetail? Or is the hunting, big game at long distance?

You need to figure out your purpose in buying a rifle scope, which will help you save a lot of time. Then you can proceed to the next step.

Tips on Purchasing A Rifle Scope

How much magnification do you need?

One of the considerable aspects of the existing rifle scope market, there are all sorts of arrangements and zoom degrees for any type of application.

What should your magnification level be for the distance you are shooting?

Numbers to the left of the X in a rifle scope represents how much bigger the target shows up than contrasted to the nude eye. A 4X classification indicates the target will certainly be 4 times bigger in the image of the scope.

Those numbers are just standards, but they can obtain you started shopping.

The following tips will help choose a magnification range:

1. If you have a carbine, seek a range in the 3X to 9X array. This magnifying is strong enough for a lot of recreational hunters.

Some manufactures have scopes starting a 1X going to 9X. A 1X setup indicates there is no magnifying whatsoever; it is a direct view. Any type of extent set up below 10X appropriates for off-hand searching and also brief range targeting.

2. 12X to 20X magnifications are for open spaces and shots longer than 600 backyards. As a rule of thumb, select a scope with above a 10X array if your shooting setting is prone or bench targeting.

Do not pay for even more magnifying than you need. Capturing specialists agree; any type of establishing more than 20X for whitetail as well as comparable animals is a waste.

Acquiring a rifle scope with too much magnifying normally leads to a badly missed shot. Shots that fizzle usually means inhumane searching.

Most shooters need less magnification, not more!

Fixed or Variable Scope

Typically, most variable rifle scopes price more than a dealt with extent. The primary reason for the boosted expense is a variable range is a lot more complicated with more effective innovation– the greater the magnifying array, the better the price.

Locate the ideal range for your needs, with as little magnification as possible. Take the money you save on zoom as well as variable or set prices, as well as spend it on much better construction.

The question you need to ask on your own; Just how commonly will you shoot at your greatest chosen zoom setting?

A fixed 4X scope is normal on most hunting rifles. This arrangement is cheap (oops, Cheaper), simple and effective.
Take into consideration a repaired high-powered range for long-range searching and competitive shooting scenarios.

For cost-effectiveness, go with a fixed scope, choose a variable scope if you have long-range applications.

What basic construction features should I look for?

Rifle scopes from builder to a builder share much of the same technologies and construction elements. A few OEM vendors carry out much of the construction from top tier scope companies.

The real nuts and bolts technologies are handled in house by their research and development divisions.

Scope tubes are going to be either argon or nitrogen purged for keeping the insides free of moisture. Most scopes tubes are suitable for mid-range hunting and competitive shooting environments.

If you hunt in extremes like Alaskan Big Game hunts, check the manufactures website for the best configurations.

If you live in extreme weather, another feature to check for is the finish. Make sure it is hard-anodized and has a solid matte or scratch resistant surface.

Give the scope a once over and see how the overall fit and finish meshes with your setup.

Rifle Scope Construction

Main Tube

A majority of rifle scope tubes built today measure 34mm, 30mm, or 1 inch in diameter. The larger the tube, the more adjustment range a shooter has. Larger tube sizes also increase durability.

For cost-effectiveness, go with a fixed scope, opt for a variable scope if you have long-range applications.

Cost is also a factor; larger tubes require costlier bases and rings. If the shooter hunts worldwide, a 1-inch scope tube is an ideal, durable size. If the shooter is an every weekend hunter, try a 30mm tube, which overall, the costs are much less.

Without question, the scope should be argon or nitrogen purged to eliminate internal fogging. Make sure the tube is shock and waterproof.

Objective lens on modern rifle scopes come in a variety of sizes, from 20mm to 72mm. If you are hunting in low-light conditions, it may be wise to purchase a larger lens.

The idea here; a larger opening allows more light through the tube, also improving resolution.

It is essential to check the distance between the scope’s bell housing and your rifle barrel. 50mm lens or larger housings require mounting higher on the rifle.

The concern; scope to eye alignment and the positioning of a cheek weld. A comfortable firing position is vital to consistent accuracy. AR-style rifles can be problematic.

If your hunting takes you deep into the woods, a larger objective lens can be heavier and bulkier to carry.

As a rule of thumb, an objective lens in the 40mm to 44mm size is adequate for most hunting applications. Do not opt for a larger lens at the sacrifice of quality glass.


Modern rifle scopes contain a variety of lenses, each coated to protect it from the environment. The quality of the glass is related to the amount of money a shooter wants to spend on their scope.

Even the cheapest scopes have good optics.

The objective lens is the lens farthest from the shooter. Its essential purpose is to transmit all captured light to the magnification assembly.

The target image is sent through a magnification lens back to the ocular assembly. Some scope builders use multiple magnification lens for a clearer image.

Scope builders take great care with this lens. The objective lens surface has the best overall coating properties.

Brightness is a direct reflection of glass quality, not just its size. Impurities in the glass and how the builder processes the product affects the clarity of the final image that reaches the shooter’s eye.

Always search out quality rifle scope glass that improves target image light transmission and prevents glare.

The erector assembly houses two lenses that flip the image to its correct orientation. This assembly may also house a magnification lens in a variable power scope. A magnification lens has vital but straightforward functions.

As magnification is lowered, the lens is pushed back towards the ocular assembly. As magnification increases, the reverse is true. Once the image is flipped properly and magnified correctly, it is sent back through to the ocular lens and its assembly.

The ocular lens is vital to the shooter. The ocular lens takes the target image, magnifies, and focuses it for presentation to the shooter. A vital point to consider; the diameter of the ocular lens determines eye relief.

If you are firing light rounds in a long barrel with no recoil, eye relief can be 3.5 inches and shorter. If the shooter is expecting heavy recoil from magnum shells, the more eye relief, the better.

The average eye relief for most scopes is between 3.6 and 4 inches.

Brief Refresher Eye Relief

Eye relief is defined as the distance between the ocular lens and the shooter’s eye. As stated above, the average is somewhere around 4 inches depending on the rifle, cartridge, and shooter’s comfort level. Eye relief is set up when the scope is mounted, and all hunting conditions should be accounted for.

Another term that needs to be mentioned is the sight picture. When a shooter looks at the ocular lens with the proper eye relief, there should be a clear edge to edge image. Without proper alignment, all the shooter sees is a bright dot or a fuzzy image. Again, this is a fundamental consequence of proper setup when mounting the scope.

Another fundamental feature to look for in rifle scopes is the types of coating for its glass. If you are a competitive shooter firing from the prone position or off a bench rest, heavy coatings may not be needed.

Hunters who hike long distances or shoot from tree stands will find a need for the best protection money can buy. Quality and types of coatings determine the clarity of the image.

Focal Plane

Two options exist when choosing where the reticle (cross-hair) is positioned, First Focal Plane or Second Focal Plane:

Inside a scope, different assemblies carry out essential functions. One of the most critical is the erector assembly. This vital part houses the reticle and is attached to the turrets.

When you change the settings by way of the turret, you are moving the erector assembly. A second focal plane scope is the most common configuration. SFP scopes have the reticle positioned behind the magnification lens.

With a reticle in the second focal plane position, the target image increases and decreases with each change in margination. The reticle stays the same size; therefore, subtensions are continually changing.

If you are using a compensating trajectory reticle, for accurate holdover and ranging, a specific magnification setting should be used. The least expensive design is a scope in the second focal plane.

Competitive shooters and long-distance hunters prefer a scope with its reticle in the first focal plane position. With this setup, the reticle is placed in front of the magnification lens.

The target image is unchanged through each magnification setting. FFP scopes have very consistent ranging, holdover, and windage corrections.


These small pieces of etched glass are fascinating technologies within a rifle scope. Years ago, a scope’s reticle was nothing more than a crosshair etched on glass. Now, there are thousands of designs and materials for every type of shooting application.

Reticles take the guesswork out of ranging, hold-overs, and wind. Another critical option when choosing the right reticle is its illumination. Every hunter encounters low-light situations, not just dusk or dawn.

Cloud cover and inclement weather can cause low-light. An illuminated reticle is an answer. Most premier scope builders design and produce their range of reticles based on the scope.

Within the last several years, third-party vendors have produced high tech reticles for a variety of builders. Horus is the most well-known of these vendors.


Adjustment knobs on the top and sides of your scope are often overlooked for flashier options. However, remember these knobs correct your elevation and windage for accurate shots. Manufactures have greatly improved turret design and feel.

There are turret designs offered by a few third-party vendors; however, scope builders have vastly improved designs and have the best designs.

Higher-end scopes have precise adjustments based on MOA or a Mil-Dot reticle. Adjustments are usually ¼ MOA or ¼ MIL-Dot.

Cheaper scopes start their adjustments at ½ MOA and so on.

The tactile feel of a turret has improved as well. Knobs have better ridges and precise clicks, telling the shooter the exact change without having to look. Ridges are raised so shooters with gloves can make changes.

Another fascinating feature of advanced turret designs is the adjustments available hidden beneath turret knobs. Builders hide back to zero, and hard stops along with other controls.

Bases, Mounts, and Rings

When they first arrive, rifle scopes look great sitting in the box. However, after a few hours or minutes, it is time to put that scope on a rifle.

Hopefully, you ordered a base and rings came with that new scope. If not, here are some suggestions and ideas to help.

Bases and rings, without proper installation, can be the weakest link in an otherwise excellent shooting system.

Once a base or rings have been installed, the shooter should never have to worry about a loose-fitting. The following are the elements of a good shooting setup.

A fixed system is precisely that, once installed, the scope cannot be removed. If there is additional equipment that the shooter wants to install later, extensions are available.

Detachable systems are the most flexible, and shooters opt for detachable components because of their convenience. Another factor, if there are two or three rifles, the shooter can move the scope quickly.

Bases are offered in either a one-piece or two-piece design. A one-piece base resists the forces of recoil better; however, the position of the base may interfere with chamber loading and shell ejection.

Weaver and Picatinny rails accommodate cross-bolts on matching rings. Angled edges provide a way for clamping the rings.

Talley bases are similar, but they are machined to accept the entire foot.

Windage adjustable bases are for the rear only and have opposing screws for centering the rings. Proprietary bases are used on rifles from manufacturers, including Sako and Ruger.

Rings are designed to match specific base styles like Picatinny or Weaver. Rings are split horizontally or vertically, and the bottom half is what engages with the base. Rings come in 1 inch, 30mm, or 34mm sizes.

Choose a ring style with the lowest height possible while giving the shooter a comfortable firing position. Keep the scope as close to the barrel as possible; this assists with proper eye alignment and cheek weld.

Ring height is another consideration for the shooter. Rings come in low, medium, and high styles.

To select the correct ring height, calculate half of the cope’s widest point. (usually the objective bell housing) Select the ring height that is slightly more than half of your scope’s widest point.

Make sure the ring clears the barrel when it is mounted. Most shooters want to fit their scope with the least amount of clearance above the barrel.

This preference helps with the line of sight and gives better results when changing distances.
