What You Need to Know About Rifle Optics
Rifle scopes allow you to specifically align a rifle at various targets by aligning your eye with the target over a range. They do this through zoom using a set of lenses within the scope. The scope’s alignment can be adapted for consideration of various ecological aspects like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based upon the sight picture you are seeing via the optic as you align the scope’s crosshair or reticle with the intended target. Many contemporary rifle optics have around eleven parts which are arranged within and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other elements. Learn about the eleven parts of glass.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The sort of focal plane an optic has decides where the reticle or crosshair is located in connection with the scopes zoom. It actually indicates the reticle is behind or before the magnification lens of the scope. Choosing the most suitable style of rifle glass is based upon what style of shooting or hunting you plan on undertaking.
First Focal Plane Glass Details
First focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based on the extent of zoom being used. The outcome is that the reticle measurements are the same at the amplified range as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are minimal
- Experienced shooters who recognize their target “hold over” and also “lead” correlations for their long guns
- Shooters who do not mind the reticle is bigger and requires more visual eyesight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane glass (SFP) include the reticle behind the magnification lens. This triggers the reticle to remain at the same dimensions relative to the level of zoom being used. The effect is that the reticle measurements alter based upon the magnification used to shoot over longer ranges considering that the markings present different increments which change with the magnification. 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. These particular kinds of glass work for:
- Long distance styles of shooting where shooters have extra time to make ballistic calculations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who select a clearer optic sight picture without area used up by the larger sized FFP reticle
Zoom for Rifle Optics
The quantity of zoom a scope provides is determined by the size, density, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Single Power Lens Scopes
A single power rifle scope comes with a zoom number designator like 4×32. This suggests 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 Optic Facts
Variable power rifle scopes use variable power levels. The power change is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some advised scope powers and the ranges where they can be effectively used. High power optics will not be as useful as lower magnification level optics considering that too much magnification can be a bad thing. The same goes for longer distances where the shooter needs to have sufficient power to see where to properly aim the rifle.
Lens Finishing for Rifle Optics
All contemporary rifle optic lenses are layered. There are different types and qualities of coatings. When thinking about luxury rifle optics and scope setups, Lens finishing can be a crucial aspect of defining the capability of the rifle. The glass lenses are one of the most crucial parts of the scope considering they are what your eye sees through while sighting a rifle in on the target. The finish on the lenses shields the lens surface area and assists with anti glare from refracted sunrays and color profiles.
HD Versus ED Scope Lens Coatings
Some scope makers also use “HD” or high-definition lens coatings which use various processes, chemicals, polarizations, and components to draw out separate colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating
Different optic lenses can also have different coatings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are coated or “multi” coated. This suggests the lens has numerous treatments applied to them. If a lens receives multiple treatments, it can show that a manufacturer is taking multiple steps to fight various natural aspects like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic covering. This additionally does not necessarily suggest the multi-coated lens is much better than a single coated lens. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle glass.
Anti-water Rifle Optic Lens Covering
Water on a scope lens doesn’t support keeping a clear sight picture through an optic in any way. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the surface area of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads move off of the scope to keep a clear, water free sight picture.
Alternatives for Installing Glass on Firearms
Installing approaches for scopes come in a few options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally come in quick release versions which use toss levers which permit rifle operators to rapidly install and remove the glass.
Hex Key Rifle Scope Rings
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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long distance precision shooting. This type of scope install is perfect for rifles which require a resilient, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle. If they all use a comparable style mount, several scopes can also be switched out on the range. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers connect nicely to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while maintaining the original sighting settings. These kinds of mounts are useful and convenient for shooting platforms which are transferred between vehicles a lot, to remove the scope from the rifle for protection, or for sight systems which are used in between a number of rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It generally costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Wetness inside your rifle optic can spoil a day on the range and your expensive optic by causing fogging and generating residue within the scope’s tube. Most optics prevent humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Normally, 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 plenty of moisture content prevention for conventional use rifles for hunting and sporting purposes, unless you plan on taking your rifle on your motorboat and are worried about the scope still functioning if it goes over the side and you can still salvage the rifle.
Gas Purged Scope Tubes
Another component of avoiding the accumulation of moisture inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less impacted by condition changes and pressure differences from the outdoor environment which might possibly permit water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
