What You Need to Know About Scopes
Rifle scopes permit you to exactly align a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account separate environmental things like wind and elevation decreases to account for bullet drop.
The scope’s function is to help the shooter understand precisely where the bullet will land based on the sight picture you are viewing through the scope as you align the scope’s crosshair or reticle with the intended target. The majority of modern rifle optics have around 11 parts which are arranged within and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other parts. See all eleven parts of an optic.
About Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the optimal type of rifle scope is based around what type of shooting you plan on doing.
About First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the extent of magnification being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non magnified range. For example, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are minimal
- Experienced shooters who know their aim point “hold over” and “lead” equations for their firearms
- Shooters who do not mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Optic Info
Second focal plane scopes (SFP) come with the reticle behind 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 reticle measurement.
- Long distance types of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots occur within much shorter ranges and distances
- Shooters who select a clearer optic sight picture without area taken up by the enlarged FFP reticle
Rifle Glass Zoom
The level of scope magnification you require depends on the form of shooting you want to do. Virtually every type of rifle optic gives some amount of zoom. The level of magnification a scope delivers is established by the dimension, thickness, and curvatures of the lenses inside of the rifle optic. The magnification level of the optic is the “power” of the opic. This implies what the shooter is checking out through the scope is magnified times the power aspect of what can normally be seen by human eyes.
About Fixed Power Lens Rifle Scopes
A single power rifle optic uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change because it is set from the factory.
Info About Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification increments. It will list the zoom amount in a configuration such as 2-10×32. These numbers mean the zoom of the scope could be set between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power adjustment is achieved by employing the power ring part of the scope near the rear of the scope by the eye bell.
Scope Power and Ranges
Here are some advised scope power levels and the ranges where they could be effectively used. Consider that higher magnification glass will not be as effective as lower magnification level glass because too much zoom can be a bad thing. The exact same concept goes for extended distances where the shooter needs to have enough power to see where to properly aim the rifle at the target.
Details on Lens Covering
All modern-day rifle scope and optic lenses are layered. There are different types and qualities of glass lens coatings. When shopping for high end rifle scope systems, Lens finishing can be a critical element of a rifle. The lenses are one of the most critical pieces of the optic considering they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens exterior and also improves anti glare from excess natural light and color discernibility.
Details on Lens Coatings – HD Versus ED
Some optic producers additionally use “HD” or high-definition lense coverings that make the most of various processes, chemical applications, polarizations, and elements to extract numerous colors and viewable target visibility through the lens. This high-definition coating is normally used with more costly high density glass which reduces light’s capability to refract through the lens glass. Some scope manufacturers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED deals with how colors are represented on the chroma spectrum and the chromatic deviance or aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious over things with hard outlines as light hits the object from specific angles.
Scope Lens Single Finish Versus Multi-Coating
Different scope lenses can also have different coverings applied to them. All lenses normally have at least some kind of treatment or finish applied to them prior to being used in a rifle scope or optic assembly. This is since the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be optimally functional in lots of kinds of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single coated lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while reducing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends upon the scope developer and the amount you paid for it. Both are signs of the lens quality.
Some scope producers likewise make it a point to define if their optic lenses are coated or “multi” covered. This suggests the lens has had multiple treatments applied to them. If a lens gets multiple treatments, it can prove that a manufacturer is taking multiple actions to fight various environmental factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This also doesn’t necessarily mean the multi-coated lens is much better than a single layered lens. Being “better” is dependent on the producer’s lens treatment technology and the quality of materials used in developing the rifle glass.
Scope Lens Anti-water Covering
Water on an optical lens doesn’t help with preserving a clear sight picture through a scope in any way. Many top of the line or high-end scope producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface area of the Steiner scope lens so the water molecules can not bind to it or create surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Optic Mounting Choices
Mounting options for scopes come in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also normally are made in quick release versions which use toss levers which permit rifle shooters to rapidly mount and remove the scope.
Hex Key Optic Ring Mounts
Basic, clamp-on design mounting scope rings use hex head screws to fix to the flattop design Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use double detached rings to support the scope, and are made from 7075 T6 billet aluminum which are manufactured for far away precision shooting. This kind of scope mount is good for rifles which require a resilient, unfailing mount which will not shift no matter how much the scope is moved or jarring the rifle takes. These are the type of mounts you should have for a devoted scope setup on a far away scouting or interdiction firearm which will pretty much never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to keep the hex screws from wiggling out after they are mounted safely in place. An example of these mounting rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used in between numerous rifles or are situationally focused.
Sealing and Gas Purging for Rifle Scope Tubes
Moisture inside your rifle optic can spoil a day on the range and your costly optic by resulting in fogging and producing residue within the scope tube. The majority of scopes protect against humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Usually, these water-resistant scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient wetness prevention for standard use rifles, unless you anticipate taking your rifle aboard a watercraft and are worried about the scope still functioning if it goes overboard and you can still salvage the gun.
Gas Purged Rifle Glass Tubes
Another component of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the scope is less influenced by temp alterations and pressure variations from the outdoor environment which might possibly allow water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
