Rifle Scope Info
Rifle scopes enable you to specifically aim a rifle at different targets by aligning your eye with the target over a range. They do this through magnifying the target by utilizing a set of lenses within the scope. The scope’s positioning can be adapted for the consideration of separate natural considerations like wind speed and elevation to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes have about eleven parts which are found within and on the exterior of the scope body. These parts consist of the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” kind of scopes. The form of focal plane a scope has decides where the reticle or crosshair is located in connection with the scopes zoom. It literally suggests the reticle is located behind or in front of the magnification lens of the optic. Deciding on the most suitable kind of rifle optic is based upon what style of hunting or shooting you anticipate doing.
First Focal Plane Scope Facts
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These types of scopes are useful for:
- Quick acquisition, far away types of shooting
- Shooting situations where estimations are low
- Experienced shooters who know their aim point “hold over” plus “lead” ratios for their rifles
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight area than a SFP reticle
Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement.
- Long distance forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots happen within much shorter spaces and ranges
- Shooters who prefer a clearer optic sight picture with less room taken up by the enlarged FFP reticle
Ins and Outs of Glass Zoom
The quantity of scope magnification you require depends on the kind of shooting you plan to do. Practically every type of rifle glass gives some amount of magnification. The quantity of zoom a scope offers is determined by the diameter, density, and curves of the lens glass within the rifle optic. The magnification level 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 aspect of what can normally be seen by human eyes.
Fixed Power Lens Optic Info
A single power rifle optic and scope uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not fluctuate since it is a fixed power scope.
Variable Power Lens Glass Facts
Variable power rifle scopes can be adjusted between magnification levels. It will list the zoom level in a format like 2-10×32. These numbers suggest the magnification of the scope can be adjusted between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power modification is accomplished by employing the power ring component of the scope near the back of the scope by the eye bell piece.
Optic Power and Range Correlation
Here are some advised scope powers and the distances where they can be successfully used. High power rifle scope glass will not be as effective as lower magnification rifle scope glass considering too much magnification can be a negative aspect depending on your shooting distance. The very same idea goes for longer distances where the shooter needs enough power to see exactly where to properly aim the rifle at the target.
About Rifle Optic Lens Finishing
All modern rifle optic lenses are layered. Lens coating can be an essential element of a rifle system when buying high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope makers also use “HD” or high-definition lens finishes which use various methods, components, chemicals, and polarizations to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Glass
Various optic lenses can also have various finishes applied to them. All lenses generally have at least some type of treatment or coating applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a finish put on it so that it will be efficiently usable in lots of types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. This lens treatment can shield 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 coated lens depends on the scope manufacturer and just how much you paid for it. Both the manufacturer and amount are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. Being “better” depends on the producer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Anti-water Lens Coatings
Water on a lens does not help with keeping 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 hydrophilic or hydrophobic finishing.
Rifle Optic Installing Alternatives
Installing options for scopes can be found in a few choices. There are the standard scope rings which are individually installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also normally can be found in quick release variations which use toss levers which permit rifle shooters to rapidly mount and dismount the glass.
Rifle Scope Mounts with Hex Key Rings
Standard, clamp style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use double independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are developed for far away accuracy shooting. This kind of scope mount is exceptional for rifle systems which require a durable, hard use mount which will not move despite how much the scope is moved about or jarring the rifle takes. These are the style of mounts you should have for a devoted scope setup on a long distance scouting or competitors firearm that will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to protect against the hex screw threads from wiggling out after they are installed safely in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts come in handy for rifle platforms which are transferred a lot, to remove the optic from the rifle for protection, or for scopes which are used between numerous rifles.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your highly-priced optic by triggering fogging and making residue within the scope’s tube. Most scopes prevent wetness from getting in the optical tube with a series of sealing O-rings which are water resistant. Generally, these water-resistant optics can be immersed within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture avoidance for conventional use rifles, unless you anticipate taking your rifle aboard a watercraft and are concerned about the scope still functioning if it is submerged in water and you can still salvage the gun.
What to Know About Rifle Glass Tube Gas Purging
Another element of avoiding the accumulation of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the glass is less altered by condition changes and pressure differences from the external environment which might potentially permit 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.
