Rifle Scope Info
Rifle scopes permit you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through zoom by making use of a series of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of separate natural aspects like wind speed and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. Most modern-day rifle scopes have about 11 parts which are found inside and on the exterior of the optic. These optic pieces include the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle glass.
About Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the optimal type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who know their aim point “hold over” and also “lead” equations for their firearm
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight space than a SFP reticle
Second Focal Plane Optic Info
Second focal plane optics (SFP) include the reticle behind the zoom lens. This triggers the reticle to remain at the exact same dimensions in relation to the amount of magnification being used. The result is that the reticle dimensions adjust based on the zoom applied to shoot over greater distances since the reticle measurements represent different increments which vary with the zoom. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick. These styles of optics are beneficial for:
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who prefer a clearer optic picture without area taken up by the larger sized FFP reticle
Magnification for Rifle Optics
The amount of scope magnification you need on your glass depends upon the form of shooting you wish to do. Almost every style of rifle scope supplies some degree of magnification. The amount of magnification a scope delivers is identified by the size, thickness, and curves of the lens glass within the rifle scope. The magnification level of the optic is the “power” of the opic. This suggests what the shooter is checking out through the scope is amplified times the power element of what can generally be seen by human eyes.
About Single Power Lens Rifle Glass
A single power rifle scope will have a magnification number designator like 4×32. This implies 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 given that it is fixed.
Info on Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power modification is accomplished by using the power ring part of the scope near the rear of the scope by the eye bell.
Rifle Glass Power Level and Ranges
Here are some recommended scope powers and the distances where they may be successfully used. Consider that high magnification scopes will not be as efficient as lower powered scopes due to the fact that excessive zoom can be a detractor. The same concept goes for longer distances where the shooter needs sufficient power to see exactly where to best aim the rifle at the target.
About Lens Coating
All contemporary rifle scope lenses are covered in special coatings. There are various types and qualities of glass lens coverings. Lens covering can be an important element of a rifle’s setup when thinking of high-end rifle optics and scope equipment. The lenses are one of the most key parts of the optic considering they are what your eye sees through while sighting a rifle in on the point of impact. The covering on the lenses offers protection to the lens exterior and also improves anti glare capabilities from refracted direct sunlight and color visibility.
HD Versus ED Lens Coatings
Some scope companies even use “HD” or high-definition lens finishings that employ different processes, polarizations, components, and chemicals to draw out numerous color ranges and viewable target definition through lenses. This high-definition finishing is commonly used with higher density lens glass which reduces light’s ability to refract by means of the lens glass. Some scope brands use “HD” to describe “ED” meaning extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic difference or aberration which is also called color distortion or fringing. Chromatic aberration can be visible over things with hard shapes as light hits the item from particular angles.
Single Scope Lens Coating Versus Multi-Coating
Different optic lenses can also have different coverings used to them. All lenses generally have at least some type of treatment or finishing applied to them before being 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 minimizing glare and other less useful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope maker and how much you spent paying for it. Both are indications of the lens quality.
Some scope manufacturers similarly make it a point to define if their optic lenses are layered or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment innovation and the quality of products used in constructing the rifle scope.
Anti-water Covering for Rifle Optics
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope makers will coat their lenses with a hydrophilic or hydrophobic finish.
Glass Installation Options
Installing options for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually are made in quick release versions which use manual levers which allow rifle shooters to quickly install and dismount the optics.
Hex Key Glass Ring Mounting Solutions
Standard, clamp style 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 a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long range accuracy shooting. This type of scope mount is perfect for rifles which require a durable, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Ring Mounting Solutions
These types 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 designed mount. The quick detach mount style is CNC crafted 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 maintaining accuracy. These types of mounts come in practical for rifles which are carried a lot, to remove the optic from the rifle for protection, or for aiming systems which are adopted in between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It usually costs around $250 USD
Details on Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day on the range and your costly optic by resulting in fogging and making residue inside of the scope tube. A lot of optics prevent wetness from going into the optical tube with a system of sealing O-rings which are waterproof. Usually, these water resistant scopes can be immersed under 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness avoidance for basic use rifles for hunting and sporting purposes, unless you anticipate taking your rifle on a boat and are concerned about the scope still working if it is submerged in water and you can still retrieve the firearm.
Gas Purged Optic Tubes
Another element of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the optic is less altered by condition changes and pressure distinctions from the external environment which might potentially permit 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 look for.
