What You Need to Know About Rifle Scopes
Rifle scopes permit you to specifically aim a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target by making use of a set of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of numerous ecological aspects like wind and elevation increases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the intended target. The majority of modern rifle scopes and optics have around 11 parts which are located inside and outside of the optic. These scope parts consist of the rifle scope’s body, lenses, elevation dials, focus rings, and other elements. See all eleven parts of an optic.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Finding the best type of rifle scope depends on what type of shooting you plan on doing.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are minor
- Experienced shooters who know their aim point “hold over” plus “lead” equations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual sight space than a SFP reticle
About 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” one hundred yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within shorter distances and ranges
- Shooters who would like a clearer optic sight picture with less room used up by the enlarged FFP reticle
Zoom for Scopes
The amount of magnification a scope provides is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Scopes
A single power rifle optic and scope comes with 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 zoom of this type of scope can not fluctuate because it is set from the factory.
Info on Adjustable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a configuration like 2-10×32. These numbers indicate the zoom of the scope could be set between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power modification is accomplished by operating the power ring part of the scope near the rear of the scope by the eye bell piece.
Power and Range Correlations
Here are some recommended scope power settings and the ranges where they can be effectively used. Remember that higher magnification glass will not be as practical as lower magnification level scopes since excessive zoom can be a bad thing. The exact same idea relates to extended ranges where the shooter needs to have increased power to see precisely where to best aim the rifle at the target.
Info on Optic Lens Coatings
All modern rifle scope lenses are covered. Lens coating can be a significant element of a rifle’s setup when looking into high end rifle optics and scope equipment.
HD Versus ED Rifle Optic Lens Coatings
Some scope producers likewise use “HD” or high-definition lens coverings which use different techniques, aspects, polarizations, and chemicals to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating for Optics
Various optic lenses can even have different coatings applied to them. All lenses normally have at least some type of treatment or finishing applied to them before being used in a rifle scope or optic assembly. Since the lens isn’t just a raw piece of glass, they require performance enhancing coatings. It becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally usable in numerous types of environments, degrees of sunlight (full light VS shade), and other shooting conditions.
This lens treatment can safeguard 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 coated lens depends on the scope producer and how much you paid for it.
Some scope manufacturers likewise make it a point to define if their optic lenses are layered or “multi” covered. This indicates the lens has several treatments applied to them. If a lens gets numerous treatments, it can show that a producer is taking multiple steps to combat different environmental factors like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This additionally doesn’t necessarily imply the multi-coated lens is much better than a single layered lens. Being “better” depends on the manufacturer’s lens treatment techniques and the quality of materials used in building the rifle glass.
Scope Lens Hydrophobic Finishing
Water on a scope’s lens doesn’t help with keeping a clear sight picture through an optic whatsoever. Many top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Installing Rifle Glass on Long Guns
Installing options for scopes can be found in a few choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also usually can be found in quick release versions which use throw levers which permit rifle operators to rapidly install and remove the scope.
Scope Mounting Solutions with Hex Key Rings
Standard, clamp-on type mounting scope rings use hex head screws to position to the flattop design 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 made from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This form of scope mount is effective for rifle systems which are in need of a resilient, unfailing mount which will not move regardless of how much the scope is moved about or jarring the rifle takes. These are the type of mounts you should have for a specialized optics system on a far away hunting or competitors long gun which will seldom need to be changed or recalibrated. Blue 242 Loctite threadlocker can also be used to protect against the hex screws from backing out after they are mounted tightly in position. An example of these rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a similar design mount. These types of mounts are convenient for long guns which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between several rifles.
Rifle Glass Tube Sealing and Gas Purging
Wetness inside your rifle glass can destroy a day on the range and your costly optic by causing fogging and producing residue inside of the scope tube. Many optics prevent moisture from entering the optical tube with a series of sealing O-rings which are waterproof. Typically, these water-resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle on your motorboat and are concerned about the scope still performing if it falls overboard and you can still rescue the rifle.
Gas Purged Rifle Glass Tubes
Another element of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the scope is less altered by temp shifts and pressure differences from the outdoor environment which might possibly allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
