Info About Scopes
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be adapted for the consideration of different environmental factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are viewing via the scope as you align the scope’s crosshair or reticle with the target. The majority of modern-day rifle scopes and optics have around eleven parts which are located within and outside of the scope. These parts include the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other parts. See all eleven parts of optics.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The kind of focal plane an optic has decides where the reticle or crosshair is located relative to the scopes magnifying adjustments. It actually suggests the reticle is located behind or ahead of the magnifying lens of the scope. Picking out the best sort of rifle optic depends upon what sort of hunting or shooting you intend on undertaking.
First Focal Plane Scope Facts
First focal plane optics (FFP) include the reticle ahead of the magnification lens. This induces the reticle to increase in size based on the extent of magnification being used. The benefit is that the reticle measurements are the same at the enhanced distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards without “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These kinds of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are small
- Experienced shooters who recognize their target “hold over” and “lead” relationships for their firearms
- Shooters who don’t mind the reticle is enlarged and requires more visual sight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle behind the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick.
- Long distance types of shooting where shooters have extra time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who choose a clearer optic picture with less area taken up by the bigger FFP reticle
Ins and Outs of Rifle Scope Zoom
The quantity of magnification a scope offers is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Scope Details
A single power rifle scope or optic will have 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 magnification of this type of scope can not change considering that it is fixed.
Adjustable Power Lens Rifle Glass Info
Variable power rifle scopes use enhanced power. The power adjustment is performed by using the power ring part of the scope near the rear of the scope by the eye bell.
Power Levels and Range Correlations
Here are some suggested scope power settings and the ranges where they could be successfully used. High power glass will not be as efficient as lower magnification level scopes since too much magnification can be a bad thing. The exact same idea goes for longer ranges where the shooter needs to have adequate power to see where to properly aim the rifle at the target.
Details on Glass Lens Coatings
All modern-day rifle optic lenses are coated. There are various types and qualities of glass finishings. When thinking about luxury rifle scope setups, Lens coating can be a vital element of defining the rifle’s capability. The lenses are one of the most significant parts of the glass because they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses shields the lens surface as well as assists with anti glare capabilities from excess direct sunlight and color visibility.
Info on Rifle Scope Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens coatings which use various processes, chemicals, elements, and polarizations to draw out a wide range of colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” implying extra-low dispersion glass.
Optic Lens Single Covering Versus Multi-Coating
Various optic lenses can also have different coatings used to them. All lenses generally have at least some type of treatment or finish applied to them prior to 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 safeguard the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope company and how much money you paid for it. Both the make and cost are indications of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the maker’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Hydrophobic Glass Lens Covering
Water on a lens doesn’t help with maintaining a clear sight picture through a scope at all. Lots of top of the line and military grade scope companies will coat their lenses with a hydrophilic or hydrophobic anti-water covering.
Optic Installation Options
Mounting options for scopes can be found in a few options. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various types of mounts also generally come in quick release versions which use throw levers which permit rifle operators to quickly install and dismount the scope.
Scope Mounts with Hex Key Rings
Standard, clamp-on design mounting optic rings use hex head screws to position to the flattop design Picatinny scope mounting rails on the tops of rifles. These kinds of scope mounts use double independent rings to support the scope, and are normally constructed from 7075 T6 billet aluminum which are developed for far away precision shooting. This kind of scope mount is great for rifles which are in need of a resilient, hard use mount which will not change despite just how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should get for a faithful scope setup on a far away scouting or competition firearm which will hardly ever need to be modified or recalibrated. Blue 242 Loctite threadlocker can also be used on screws to keep the hex screws from backing out after they are installed firmly in position. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Optic Rings
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. If they all use a comparable design mount, several scopes can often be switched out. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining precision. These types of mounts are useful and handy for rifles which are transferred between vehicles a lot, to take off the glass from the rifle for protection, or for scopes which are adopted between multiple rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It typically costs around $250 USD
Sealing and Gas Purging for Glass Tubes
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and producing residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Info Around Rifle Scope Tube Gas Purging
Another part of preventing the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently occupied by the gas, the glass is less affected by temperature alterations and pressure differences from the outside environment which may potentially allow water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
