Info Rifle Optics
Rifle scopes enable you to exactly aim a rifle at different targets by lining up your eye with the target at range. They accomplish this through zoom using a series of lenses inside the scope. The scope’s alignment can be adapted to take into account numerous ecological aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing with the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of modern-day rifle scopes have about 11 parts which are arranged within and externally on the optic. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other components. See all eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the best type of rifle optic depends on what type of shooting you plan on doing.
First Focal Plane Glass Info
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the level of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non amplified distance. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the very same tick at 100 yards using 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are very little
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” ratios for their rifles
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Second Focal Plane Scope Info
Second focal plane scopes (SFP) come with the reticle behind the zoom 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.
- Far away types of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within much shorter spaces and ranges
- Shooters who desire a clearer optic picture with less space used up by the enlarged FFP reticle
Details on Scope Zoom
The quantity of magnification a scope provides 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 Single Power Lens Glass
A single power rifle optic or scope will have a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this type of optic can not adjust since it is a fixed power scope.
About Variable Power Lens Rifle Glass
Variable power rifle scopes use enhanced power. The power adjustment is handled using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Rifle Optics
Here are some suggested scope powers and the ranges where they may be successfully used. Bear in mind that higher magnification glass will not be as efficient as lower powered optics and scopes due to the fact that too much zoom can be a detractor. The same concept goes for longer distances where the shooter needs adequate power to see exactly where to properly aim the rifle at the target.
Details on Lens Coverings
All modern-day rifle optic and scope lenses are layered. There are various types and qualities of finishes. When looking at luxury rifle optical devices, Lens covering can be a vital component of a rifle. The glass lenses are among the most important pieces of the glass due to the fact that they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses safeguards the lens surface and also assists with anti glare capabilities from excess light and color exposure.
ED Versus HD Rifle Scopes
Some scope makers also use “HD” or high-definition lens coatings which use various techniques, polarizations, components, and chemicals to draw out separate colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Optic Lens Covering Versus Multi-Coating
Various optic lenses can even have various coverings applied to them. All lenses typically have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic. This is due to the fact that the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently usable in numerous kinds of environments, degrees of light (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is typically a protective and enhancing multi-purpose treatment. 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 optic. The quality of a single layered lens depends upon the scope manufacturer and how much money you paid for it. Both the make and cost are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. This implies the lens has multiple treatments applied to them. If a lens gets several treatments, it can prove that a producer is taking several steps to combat different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t necessarily imply the multi-coated lens is better than a single covered lens. Being “much better” is dependent on the manufacturer’s lens treatment technology and the quality of products used in constructing the rifle glass.
Info on Hydrophobic Finish
Water on a lens does not help with maintaining a clear sight picture through a scope at all. Many top of the line and high-end optic companies will coat their lenses with a hydrophilic or hydrophobic anti-water finishing.
Choices for Mounting Rifle Scopes on Firearms
Mounting solutions for scopes come in a couple of choices. 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 usually come in quick release variations which use manual levers which enable rifle shooters to quickly mount and remove the scope.
Rifle Glass Mounts with Hex Key Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope installation 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 accuracy shooting. This type of scope mount is great for rifles which require a durable, sound mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Rings
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 complementary style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining accuracy. These types of mounts are useful and practical for shooting platforms which are moved around a lot, to remove the glass from the rifle for protection, or for optics which are utilized between numerous rifles. An example of this mount type is the 30mm mount from the Vortex Optics manufacturer. It normally costs around $250 USD
Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your pricey optic by triggering fogging and developing residue inside of the scope tube. A lot of scopes prevent wetness from entering the scope tube with a system of sealing O-rings which are water resistant.
Info Around Rifle Scope Tube Gas Purging
Another component of preventing the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this space is currently occupied by the gas, the optic is less affected by temperature alterations and pressure distinctions from the outdoor 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.
