Rifle Scope Facts
Rifle scopes permit you to precisely aim a rifle at various targets by aligning your eye with the target over a distance. They do this through magnifying the target by making use of a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account varied environmental elements like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the target. The majority of modern rifle scopes and optics have around 11 parts which are located internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other parts. See all eleven parts of optics.
About Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the best type of rifle glass depends on what type of shooting you plan to do.
Info on First Focal Plane Glass
First focal plane optics (FFP) include the reticle ahead of the zoom lens. This induces the reticle to increase in size based upon the extent of magnification being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are minimal
- Experienced shooters who know their target “hold over” plus “lead” correlations for their rifles
- Shooters who don’t mind the reticle is enlarged and requires more visual sight room than a SFP reticle
Second Focal Plane Scope Facts
Second focal plane optics (SFP) feature the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who select a clearer optic sight picture with less room used up by the enlarged FFP reticle
Zoom for Glass
The quantity of scope magnification you need on your optic depends upon the type of shooting you wish to do. Just about every style of rifle scope supplies some level of zoom. The volume of magnification a scope supplies is identified by the dimension, thickness, and curvatures of the lenses within the rifle scope. The zoom of the optic is the “power” of the opic. This suggests what the shooter is looking at through the scope is magnified times the power factor of what can usually be seen by human eyes.
About Fixed Single Power Lens Rifle Glass
A single power rifle scope uses a magnification 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 adjust given that it is set from the factory.
Variable Power Lens Glass Info
Variable power rifle scopes use enhanced power. The power modification is achieved by the power ring part of the scope near the back of the scope by the eye bell.
Glass Power Level and Ranges
Here are some recommended scope power settings and the distances where they may be efficiently used. Remember that high magnification glass will not be as effective as lower powered optics and scopes since too much zoom can be a detractor. The exact same concept goes for longer distances where the shooter needs increased power to see precisely where to properly aim the rifle.
Lens Finishing for Rifle Glass
All present day rifle optic and scope lenses are covered. Lens finishing can be a crucial aspect of a shooting platform when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope brands also use “HD” or high-definition lens finishings which use different procedures, components, chemicals, and polarizations to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Rifle Optic Lens Single Coating Versus Multi-Coating
Different optic lenses can likewise have different coatings used to them. All lenses typically have at least some type of treatment or finishing used to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered 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” coated. This indicates the lens has numerous treatments applied to them. If a lens receives multiple treatments, it can establish that a maker is taking several steps to fight different natural factors like an anti-glare finishing, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally does not always imply the multi-coated lens will perform better than a single layered lens. Being “much better” is dependent on the maker’s lens treatment solutions and the quality of materials used in creating the rifle scope.
Hydrophobic Lens Coatings
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Many top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic coating which is water repellent.
Choices for Mounting Optics on Firearms
Installing solutions for scopes can be found in a couple of choices. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release variations which use toss levers which allow rifle operators to quickly install and dismount the scope.
Glass Mounting Solutions with Hex Key Rings
Basic, clamp style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use two individual rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This kind of scope mount is great for rifles which need a long lasting, hard use mount which will not move regardless of just how much the scope is moved about or jarring the rifle takes. These are the design of mounts you really want to have for a devoted optics setup on a reach out and touch someone hunting or tournament rifle which will almost never need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to prevent the hex screws from backing out after they are mounted securely in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Scope Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly take off a scope from a rifle and reattach it to a different rifle. If they all use a comparable style mount, several scopes can often be switched in the field. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect tightly to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted while maintaining the original sighting settings. These kinds of mounts come in handy for rifles which are moved around a lot, to take off the scope from the rifle for protection, or for scopes which are employed in between numerous rifles. An example of this mount type is the 30mm mount designed by the Vortex Optics manufacturer. It generally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle scope can ruin a day of shooting and your pricey optic by triggering fogging and creating residue inside of the scope tube. Many scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another element of preventing the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the scope is less impacted by condition changes and pressure distinctions from the outdoor environment which could potentially enable water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
