What You Need to Know About Scopes
Rifle scopes permit you to specifically align a rifle at various targets by aligning your eye with the target at range. They do this through magnification using a set of lenses within the scope. The scope’s alignment can be adjusted to account for different environmental considerations like wind speed and elevation to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are seeing using the optic as you line up the scope’s crosshair or reticle with the intended point of impact. The majority of contemporary rifle scopes and optics have about 11 parts which are found inside and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other components. See all eleven parts of a rifle scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane a scope has determines where the reticle or crosshair lies in relation to the optic’s magnification. It simply suggests the reticle is situated behind or in front of the magnification lens of the optic. Picking the most beneficial style of rifle scope is based on what sort of shooting you anticipate undertaking.
About First Focal Plane Optics
First focal plane glass (FFP) include the reticle before the zoom lens. This causes the reticle to increase in size based on the level of zoom being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who recognize their target “hold over” plus “lead” ratios for their long guns
- Shooters who do not mind the reticle is enlarged and uses up more visual eyesight room than a SFP reticle
Info About 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” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within much shorter ranges and proximities
- Shooters who desire a clearer optic sight picture without area taken up by the bigger FFP reticle
Rifle Glass Magnification
The quantity of scope zoom you need on your optic depends on the kind of shooting you desire to do. Practically every type of rifle scope supplies some level of magnification. The quantity of zoom a scope offers is established by the dimension, density, and curves of the lens glass within the rifle optic. The magnifying level of the optic is the “power” of the glass. This denotes what the shooter is looking at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Rifle Optics
A single power rifle scope or optic will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not change since it is a fixed power optic.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes have adjustable power. It will note the magnification level in a configuration such as 2-10×32. These numbers imply the magnification of the scope can be adjusted between 2x and 10x power. This also incorporates the powers in-between 2 and 10. The power modification is accomplished using the power ring part of the scope near the rear of the scope by the eye bell piece.
Power and Range
Here are some advised scope power settings and the distances where they can be successfully used. Highly magnified scopes will not be as effective as lower magnification optics due to the fact that too much zoom can be a bad thing. The same idea goes for extended distances where the shooter needs sufficient power to see exactly where to properly aim the rifle at the target.
Optic Lens Finish
All top teir rifle scope and optic lenses are layered. Lens covering is an important element of a rifle system when considering high end rifle optics and scope setups.
HD Versus ED Rifle Scope Lens Coatings
Some scope brands also use “HD” or high-definition lens coverings which use different processes, polarizations, components, and chemicals to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating
Various optic lenses can likewise have various coatings applied to them. All lenses generally have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends upon the scope maker and how much you spent for it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. This indicates the lens has had several treatments applied to the surfaces. If a lens receives numerous treatments, it can indicate that a manufacturer is taking multiple actions to fight different environmental factors like an anti-glare covering, a scratch resistant anti-abrasion covering, followed by a hydrophilic finish. This additionally does not always mean the multi-coated lens is much better than a single layered lens. Being “better” is dependent on the manufacturer’s lens treatment solutions and the quality of glass used in creating the rifle glass.
Optic Lens Anti-water Coating
Water on a lens does not help with preserving a clear sight picture through a scope at all. Lots of top of the line and military grade optic makers will coat their lenses with a hydrophobic or hydrophilic finishing.
Optic Installation Alternatives
Mounting options for scopes come in a few options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically can be found in quick release variations which use toss levers which permit rifle shooters to rapidly mount and remove the glass.
Hex Key Rifle Scope Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is perfect for rifles which require a long lasting, sound mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be switched out if they all use a compatible design mount. These types of mounts come in handy for long guns which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for scopes which are used between multiple rifles or are situationally focused.
Sealing and Gas Purging for Optic Tubes
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by bringing about fogging and producing residue inside of the scope tube. A lot of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are waterproof.
Details on Glass Tube Gas Purging
Another element of avoiding the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is already occupied by the gas, the glass is less impacted by temp shifts and pressure variations from the outdoor environment which might possibly allow 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.
