Optic Details
Rifle scopes permit you to precisely align 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 series of lenses inside the scope. The scope’s positioning can be adapted for consideration of numerous natural elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended point of impact. Many modern-day rifle optics have about eleven parts which are located inside and on the exterior of the scope. These scope parts consist of the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of glass.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the best type of rifle scope is based around what type of shooting you plan to do.
Info on First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are very little
- Experienced shooters who know their aim point “hold over” plus “lead” ratios for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Second Focal Plane Scope Details
Second focal plane optics (SFP) include the reticle behind the magnification 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.
- Long distance types of shooting where shooters have additional time to make ballistic computations
- Shooting where most of the shots happen within much shorter proximities and ranges
- Shooters who desire a clearer optic sight picture with less area used up by the larger size FFP reticle
Ins and Outs of Rifle Scope Zoom
The level of scope zoom you need on your glass is based on the kind of shooting you want to do. Virtually every type of rifle optic offers some level of magnification. The level of zoom a scope delivers is established by the size, thickness, and curves of the lens glass within the rifle scope. The magnification level of the scope is the “power” of the glass. This suggests what the shooter is looking at through the scope is amplified times the power factor of what can usually be seen by human eyes.
Fixed Single Power Lens Scopes
A single power rifle scope and optic uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust given that it is fixed.
Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification increments. It will list the zoom level in a format like 2-10×32. These numbers imply the magnification of the scope can be set between 2x and 10x power. This additionally includes the power levels in-between 2 and 10. The power modification is accomplished by employing the power ring part of the scope near the back of the scope by the eye bell.
Scope Power and Ranges
Here are some suggested scope power settings and the ranges where they could be successfully used. Bear in mind that high power glass will not be as effective as lower powered scopes because too much magnification can be a bad thing. The exact same concept applies to longer ranges where the shooter needs to have adequate power to see exactly where to best aim the rifle.
Optic Lens Finish
All modern rifle optic and scope lenses are coated. There are various types and qualities of finishings. When thinking about high end rifle optics and scope units, Lens finishing can be an essential aspect of defining the capability of the rifle. The glass lenses are among the most vital components of the scope due to the fact that they are what your eye looks through while sighting a rifle in on the point of impact. The finish on the lenses shields the lens exterior and improves anti glare capabilities from excess sunshine and color presence.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens finishes which use different techniques, chemicals, elements, and polarizations to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Scopes
Different optic lenses can likewise have different finishes used to them. All lenses usually have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is usually a protective and improving multi-purpose treatment. 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 optic. The quality of a single covered lens depends on the scope producer and how much money you spent for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Lens Finish
Water on a scope’s lens does not help with maintaining a clear sight picture through an optic in any way. Numerous top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the exterior surfaces of the Steiner scope lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Glass on Long Guns
Mounting solutions for scopes are available in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also usually come in quick release variations which use manual levers which allow rifle shooters to quickly mount and dismount the glass.
Hex Key Rifle Optic Rings
Basic, clamp style mounting scope rings use hex head screws to position to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use double separate rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This type of scope mount is effective for rifles which are in need of a durable, rock solid mount which will not change no matter how much the scope is moved about or abuse the rifle takes. These are the design of mounts you really want to have for a devoted optics system on a reach out and touch someone hunting or sniper competition rifle which will rarely need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to keep the hex screws from backing out after they are mounted securely in position. An example of these mounting rings are the 30mm style from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Rifle Glass Ring Mounts
These types 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 design mount, a number of scopes can also be swapped out in the field. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top type Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining precision. These types of mounts are useful and practical for rifles which are moved around a lot, to remove the optic from the rifle for protection, or for scopes which are used in between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day on the range and your highly-priced optic by causing fogging and creating residue inside of the scope tube. The majority of optics prevent humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Usually, these optics can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture prevention for standard use rifles, unless you intend on taking your rifle on boats and are worried about the scope still performing if it falls overboard and you can still recover the firearm.
Gas Purged Rifle Scope Tubes
Another component of preventing the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the glass is less influenced by temperature shifts and pressure variations from the outdoor environment which could potentially enable water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
