Rifle scopes enable 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 using a series of lenses within the scope. The scope’s alignment can be dialed in for the consideration of numerous environmental considerations like wind and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes and optics have about eleven parts which are found internally and outside of the scope. These parts consist of the rifle scope’s body, lenses, adjustment dials, focus rings, and other parts. See all eleven parts of an optic.
Rifle Optic Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane a scope has identifies where the reticle or crosshair is located in regard to the scopes magnification. It actually suggests the reticle is located behind or ahead of the magnification lens of the scope. Deciding on the most desired kind of rifle glass depends on what style of shooting or hunting you anticipate undertaking.
First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who have an idea for their target “hold over” and also “lead” ratios for their rifles
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) come with the reticle to the rear of the magnification 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 reticle measurement.
- Long distance kinds of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots take place within much shorter ranges and spaces
- Shooters who select a clearer optic sight picture with less space used up by the larger sized FFP reticle
The amount of scope zoom you need on your scope depends upon the type of shooting you desire to do. Virtually every kind of rifle optic supplies some degree of magnification. The amount of magnification a scope provides is established by the size, density, and curvatures of the lens glass within the rifle scope. The magnifying level of the scope is the “power” of the opic. This signifies what the shooter is aiming at through the scope is amplified times the power element of what can normally be seen by human eyes.
About Fixed Power Lens Rifle Glass
A single power rifle optic and scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not change given that it is a set power scope.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be changed between magnification increments. It will note the magnification level in a configuration such as 2-10×32. These numbers suggest the magnification of the scope could be adjusted between 2x and 10x power. This always includes the power levels in-between 2 and 10. The power modification is achieved using the power ring component of the scope near the rear of the scope by the eye bell.
Rifle Scope Power and Range Correlation
Here are some recommended scope power levels and the ranges where they can be efficiently used. High power glass will not be as efficient as lower powered optics given that too much magnification can be a negative aspect depending on your shooting distance. The same relates to longer distances where the shooter needs sufficient power to see precisely where to properly aim the rifle.
About Rifle Scope Lens Finishing
All modern rifle scope and optic lenses are layered. Lens finishing is an essential element of a rifle system when thinking about high end rifle optics and scope equipment.
ED Versus HD Rifle Optics
Some scope manufacturers likewise use “HD” or high-definition lens finishings which use different techniques, polarizations, chemicals, and elements to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can also have various coverings applied to them. All lenses generally have at least some kind of treatment or covering 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 becomes part of the finely tuned optic. It requires a coating to be applied to it so that it will be optimally functional in many kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
Single coated lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single layered lens depends on the scope producer and how much you spent on it. The scope’s maker and cost are signs of the lens quality.
Some scope manufacturers likewise make it a point to specify if their optic lenses are layered or “multi” covered. This suggests the lens has had several treatments applied to the surfaces of the glass. If a lens gets numerous treatments, it can indicate that a manufacturer is taking numerous actions to combat different environmental aspects like an anti-glare finish, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This also does not always suggest the multi-coated lens is better than a single coated lens. Being “much better” depends on the maker’s lens treatment solutions and the quality of products used in building the rifle scope.
Rifle Scope Lens Anti-water Coating
Water on an optic’s lens does not improve maintaining a clear sight picture through an optic in any way. Numerous top of the line and premium scope makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for the surface of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Options for Installing Rifle Glass on Firearms
Installing approaches for scopes can be found in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also typically come in quick release versions which use toss levers which permit rifle operators to quickly mount and dismount the optics.
Hex Key Rifle Optic Rings
Basic, clamp-on type mounting optic rings use hex head screws to position to the flattop design Picatinny scope mount rails on rifles. These forms of scope mounts use two individual rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This kind of scope mount is very good for rifles which require a resilient, unfailing mount which will not move despite just how much the scope is moved or abuse the rifle takes. These are the type of mounts you really want to have for a devoted optics system on a long distance hunting or hard target interdiction firearm that will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to keep the hex screws from backing out after they are installed securely in position. An example of these mounting rings are the 30mm style made by Vortex Optics. The set generally costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. A wide range of scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining the original sighting settings. These kinds of mounts are useful and beneficial for shooting platforms which are transferred between vehicles a lot, to take off the glass from the rifle for protection, or for aiming systems which are utilized between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It typically costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle glass can wreck a day of shooting and your expensive optic by causing fogging and producing residue within the scope tube. The majority of scopes protect against wetness from getting in the scope tube with a series of sealing O-rings which are waterproof. Usually, these water resistant optics can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture prevention for basic use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are worried about the scope still working if it falls overboard and you can still retrieve the rifle.
What to Know About Rifle Scope Tube Gas Purging
Another element of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Since this area is currently occupied by the gas, the optic is less influenced by condition changes 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 exist. These are good qualities of a good rifle scope to seek out.
