What You Need to Know About Rifle Optics
Rifle scopes allow you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through magnification using a series of lenses within the scope. The scope’s alignment can be dialed in to take into account many ecological aspects like wind and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based on the sight picture you are seeing through the scope as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have around 11 parts which are found inside and outside of the scope. These parts include the rifle scope’s body, lenses, modification turrets, objective focus rings, and other parts. Learn about the eleven parts of rifle glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has decides where the reticle or crosshair lies in connection with the optic’s magnification. It literally suggests the reticle is behind or before the magnification lens of the scope. Looking for the very best style of rifle optic is based on what form of hunting or shooting you plan on undertaking.
About First Focal Plane Glass
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who recognize their aim point “hold over” as well as “lead” relationships for their long gun
- Shooters who do not mind the reticle is bigger and requires more visual sight room than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who would like a clearer optic picture without room taken up by the larger size FFP reticle
Zoom for Glass
The extent of scope zoom you need on your scope depends upon the sort of shooting you choose to do. Pretty much every kind of rifle scope gives some amount of magnification. The level of magnification a scope delivers is determined by the diameter, thickness, and curves of the lens glass within the rifle optic. The magnifying level of the scope is the “power” of the scope. This indicates what the shooter is looking at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Single Power Lens Rifle Glass Info
A single power rifle scope or optic uses a zoom number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not change considering that it is a fixed power scope.
Variable Power Lens Scopes
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom amount in a configuration such as 2-10×32. These numbers indicate the zoom of the scope can be set between 2x and 10x power. This additionally utilizes the power levels in-between 2 and 10. The power manipulation is achieved by working with the power ring component of the scope near the rear of the scope by the eye bell piece.
Rifle Glass Power and Ranges
Here are some advised scope powers and the ranges where they may be successfully used. Consider that higher magnification optics and scopes will not be as practical as lower powered glass due to the fact that increased magnification can be a bad thing. The exact same concept relates to extended ranges where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Glass Lens Coating
All modern rifle optic lenses are covered in special coatings. There are various types and qualities of glass coatings. Lens finishing is a crucial aspect of a rifle when contemplating high end rifle optics and targeting units. The lenses are among the most significant components of the scope as 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 assists with anti glare from refracted sunshine and color presence.
HD Versus ED Rifle Optic Lens Coatings
Some scope producers also use “HD” or high-definition lens coatings which use different techniques, aspects, chemicals, and polarizations to draw out various colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Scope Lens Finishing Versus Multi-Coating
Different scope lenses can even have various finishes applied to them. All lenses usually have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t just a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally usable in numerous types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while minimizing glare and other less helpful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are covered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces. If a lens gets multiple treatments, it can indicate that a manufacturer is taking several steps to combat different natural elements like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This also doesn’t necessarily suggest the multi-coated lens will perform much better than a single covered lens. Being “much better” hinges on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Scope Lens Anti-water Covering
Water on a lens does not assist with keeping a clear sight picture through a scope at all. Numerous top of the line and high-end optic makers will coat their lenses with a hydrophilic or hydrophobic anti-water coating.
Rifle Optic Installing Options
Installing solutions for scopes can be found in a few options. There are the standard scope rings which are individually installed to the scope and one-piece scope mounts which cradle the scope. These different kinds of mounts also usually come in quick release variations which use manual levers which permit rifle operators to quickly install and remove the optics.
Hex Key Rifle Scope Ring Mounts
Normal, clamp style mounting scope rings use hex head screws to mount to the flattop design 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 is designed for long range accuracy shooting. This type of scope install is fine for rifles which need a long lasting, sound mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly 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 design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, removed from the rifle, and remounted while maintaining precision. These kinds of mounts come in handy for shooting platforms which are carried a lot, to remove the scope from the rifle for protection, or for scopes which are employed in between a number of rifles. An example of this mount type is the 30mm mount from Vortex Optics. It normally costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your pricey optic by inducing fogging and developing residue inside of the scope tube. The majority of scopes protect against humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Generally, these scopes can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample wetness prevention for basic use rifles, unless you plan on taking your rifle on your motorboat and are worried about the optic still working if it goes over the side and you can still recover the gun.
Gas Purged Scope Tubes
Another element of preventing the accumulation of moisture within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less influenced by condition changes and pressure differences from the outside environment which might potentially enable water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
