Rifle scopes enable you to exactly align a rifle at different targets by lining up your eye with the target over a range. They do this through magnifying the target using a series of lenses inside the scope. The scope’s alignment can be adapted to take into account different environmental factors like wind and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the target. A lot of modern-day rifle optics have around 11 parts which are found inside and on the exterior of the scope. These optic pieces include the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other parts. Learn about the eleven parts of glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The type of focal plane an optic has decides where the reticle or crosshair is located in relation to the optic’s magnifying adjustments. It literally indicates the reticle is behind or before the magnifying lens of the optic. Picking out the most reliable type of rifle scope is based upon what style of shooting you plan on undertaking.
About First Focal Plane Optics
First focal plane scopes (FFP) include the reticle before the magnifying lens. This triggers the reticle to increase in size based upon the extent of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who recognize their aim point “hold over” as well as “lead” correlations for their firearms
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick.
- Long distance kinds of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots happen within shorter distances and ranges
- Shooters who choose a clearer optic picture with less space taken up by the enlarged FFP reticle
Magnification for Rifle Glass
The amount of scope zoom you require depends on the kind of shooting you desire to do. Virtually every type of rifle scope provides some level of magnification. The volume of zoom a scope supplies is established by the diameter, thickness, and curves of the lens glass inside of the rifle scope. The magnification of the optic is the “power” of the glass. This means what the shooter is observing through the scope is amplified times the power aspect of what can normally be seen by human eyes.
Fixed Single Power Lens Optic Details
A single power rifle optic and scope uses a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change since it is a fixed power scope.
Info About Adjustable Power Lens Optics
Variable power rifle scopes can be adjusted between magnification power levels. It will note the zoom degree in a configuration such as 2-10×32. These numbers mean the zoom of the scope could be adjusted between 2x and 10x power. This always incorporates the powers in-between 2 and 10. The power modification is achieved by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some advised scope power levels and the ranges where they could be successfully used. Bear in mind that higher power glass will not be as effective as lower powered optics and scopes since excessive magnification can be a bad thing. The same idea relates to extended distances where the shooter needs increased power to see where to properly aim the rifle.
Rifle Glass Lens Finishing
All modern-day rifle optic and scope lenses are coated. There are different types and qualities of finishes. When thinking about high end rifle scope units, Lens finishing can be a crucial component of a rifle. The lenses are one of the most key pieces of the glass because they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses shields the lens surface and also helps with anti glare from refracted natural light and color perception.
HD Versus ED Lens Coatings
Some scope makers also use “HD” or high-definition lens finishes which use different methods, chemicals, polarizations, and aspects to draw out a wide range of colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Optics
Various optic lenses can likewise have various finishes used to them. All lenses typically have at least some type of treatment or finishing used to them before being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less useful 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 also make it a point to define if their optic lenses are coated or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Anti-water Lens Coatings
Water on a scope lens does not improve keeping a clear sight picture through a scope at all. Lots of top of the line and premium optic producers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the surface of the Steiner scope lens so the water particles can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Options for Installing Glass on Long Guns
Installing approaches for scopes come in a couple of options. There are the basic scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different kinds of mounts also generally are made in quick release versions which use throw levers which enable rifle operators to quickly mount and remove the glass.
Hex Key Rifle Glass Ring Mounting Solutions
Standard, 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 made from 7075 T6 billet aluminum which are created for long distance accuracy shooting. This type of scope install is great for rifles which need a resilient, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Glass Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and attach it to a different rifle. Numerous scopes can even be swapped out if they all use a similar style mount. These types of mounts are convenient for rifle platforms which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Info on Glass Tube Sealing and Gas Purging
Moisture inside your rifle glass can wreck a day of shooting and your expensive optic by resulting in fogging and developing residue within the scope tube. Many optics protect against moisture from getting in the scope tube with a system of sealing O-rings which are water resistant. Usually, these water resistant scopes can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness avoidance for conventional use rifles, unless you plan on taking your rifle boating and are worried about the optic still working if it goes overboard and you can still recover the rifle.
Gas Purged Rifle Optic Tubes
Another component of avoiding the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the scope is less affected by condition changes and pressure variations from the outside environment which could possibly permit water vapor to permeate 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.
