What You Need to Know About Scopes
Rifle scopes enable you to exactly aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom by making use of a series of lenses within the scope. The scope’s alignment can be adjusted to account for separate natural factors like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the intended point of impact. Most modern rifle scopes have about 11 parts which are arranged within and on the exterior of the scope body. These parts include the rifle scope’s body, lenses, adjustment turrets, focus rings, and other elements. See all eleven parts of a scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has decides where the reticle or crosshair is located in regard to the scopes zoom. It actually means the reticle is located behind or before the magnifying lens of the scope. Deciding on the most beneficial form of rifle optic depends upon what type of hunting or shooting you intend on doing.
First Focal Plane Optic Info
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This causes the reticle to increase in size based upon the level of magnification being used. The result is that the reticle measurements are the same at the magnified range as they are at the non amplified range. For example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where calculations are minor
- Experienced shooters who have an idea for their target “hold over” and also “lead” relationships for their rifles
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane scopes (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots occur within much shorter distances and ranges
- Shooters who like a clearer optic sight picture with less room taken up by the enlarged FFP reticle
About Glass Magnification
The amount of magnification a scope supplies is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Single Power Lens Rifle Optics
A single power rifle optic or scope comes with a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change because it is a fixed power optic.
About Adjustable Power Lens Glass
Variable power rifle scopes use enhanced power. The power modification is performed by the power ring part of the scope near the back of the scope by the eye bell.
Power Levels and Range
Here are some recommended scope power levels and the distances where they can be successfully used. Bear in mind that high power scopes and optics will not be as efficient as lower powered scopes due to the fact that excessive magnification can be a bad thing. The very same idea applies to extended ranges where the shooter needs to have increased power to see where to best aim the rifle.
Lens Coating for Rifle Optics
All modern rifle optic lenses are covered in special coatings. There are various types and qualities of lens coverings. Lens finishing can be an essential aspect of a rifle’s setup when contemplating high-end rifle optics and scope systems. The lenses are among the most key pieces of the scope given that they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses safeguards the lens surface area and helps with anti glare from refracted sunshine and color visibility.
ED Versus HD Rifle Optics
Some scope manufacturers likewise use “HD” or high-definition lens coverings which use different methods, elements, polarizations, and chemicals to draw out a wide range of colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Scopes
Different optic lenses can also have various coverings applied to them. All lenses normally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while reducing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope developer and how much you spent paying for it. Both the make and cost are indications of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This means the lens has had multiple treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a manufacturer is taking several steps to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This also does not always imply the multi-coated lens will perform much better than a single layered lens. Being “much better” is dependent on the manufacturer’s lens treatment techniques and the quality of components used in constructing the rifle glass.
Anti-water Covering for Rifle Glass
Water on a lens does not help with preserving a clear sight picture through a scope at all. Many top of the line and military grade scope makers will coat their lenses with a hydrophobic or hydrophilic finishing which is water repellent.
Options for Installing Optics on Long Guns
Mounting approaches for scopes can be found in a few options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually come in quick release versions which use throw levers which enable rifle shooters to quickly install and remove the glass.
Hex Key Glass Ring Mounts
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design 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 distance precision shooting. This type of scope install is great for rifles which require a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and attach it to a different rifle. Multiple scopes can even be switched out if they all use a compatible design mount. These types of mounts are convenient for long guns which are carried a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used in between several rifles or are situationally focused.
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle scope can wreck a day of shooting and your costly optic by triggering fogging and making residue within the scope’s tube. Many scopes protect against wetness from entering the optical tube with a system of sealing O-rings which are waterproof. Generally, these water-resistant optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture content prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on a boat and are worried about the optic still performing if it falls overboard and you can still find the rifle.
Info Around Rifle Scope Tube Gas Purging
Another element of preventing the buildup of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is currently taken up by the gas, the optic is less impacted by temp alterations and pressure variations from the external environment which could potentially enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
