About Rifle Optics
Rifle scopes enable you to specifically align a rifle at different targets by aligning your eye with the target at range. They do this through zoom by using a set of lenses inside the scope. The scope’s alignment can be dialed in for the consideration of varied environmental considerations like wind and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based upon the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle optics have around eleven parts which are found inside and externally on the optic. These parts consist of the rifle scope’s body, lenses, windage turrets, focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The sort of focal plane a scope has establishes where the reticle or crosshair is located in regard to the scopes zoom. It literally indicates the reticle is behind or ahead of the magnification lens of the optic. Deciding upon the most reliable form of rifle scope depends upon what type of shooting you intend on doing.
First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where computations are very little
- Experienced shooters who have an idea for their target “hold over” plus “lead” correlations for their firearm
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle to the rear of 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.
- Far away styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within shorter distances and ranges
- Shooters who choose a clearer optic sight picture without area used up by the bigger FFP reticle
Rifle Optic Zoom
The quantity of scope zoom you need on your scope is based on the sort of shooting you want to do. Pretty much every kind of rifle glass delivers some amount of zoom. The amount of zoom a scope gives is established by the diameter, thickness, and curvatures of the lenses within the rifle optic. The magnification of the optic is the “power” of the opic. This means what the shooter is observing through the scope is amplified times the power element of what can usually be seen by human eyes.
About Fixed Single Power Lens Rifle Glass
A single power rifle scope will have a zoom number designator like 4×32. This implies 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 since it is fixed.
Info About Variable Power Lens Optics
Variable power rifle scopes can be changed between magnification levels. It will note the zoom level in a configuration such as 2-10×32. These numbers suggest the zoom of the scope can be set in between 2x and 10x power. This additionally incorporates the power levels in-between 2 and 10. The power shift is achieved by applying the power ring part of the scope near the back of the scope by the eye bell piece.
Power Levels and Range
Here are some recommended scope power levels and the ranges where they could be successfully used. High power rifle scope glass will not be as effective as lower magnification level glass considering that too much magnification can be a negative aspect depending on your shooting distance. The same concept applies to extended ranges where the shooter needs increased power to see exactly where to best aim the rifle at the target.
Lens Covering for Rifle Scopes
All modern rifle optic and scope lenses are coated. There are different types and qualities of lens finishes. When researching high end rifle optics and scope systems, Lens coating can be a crucial component of a rifle. The lenses are among the most key parts of the optic as they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses safeguards the lens surface as well as helps with anti glare capabilities from excess sunshine and color discernibility.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens coverings which use different procedures, aspects, chemicals, and polarizations to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Glass Lens Finish Versus Multi-Coating
Various optic lenses can likewise have different coverings applied to them. All lenses normally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while minimizing 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 manufacturer 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” covered. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Anti-water Finish for Rifle Glass
Water on a scope lens does not assist with keeping a clear sight picture through a scope whatsoever. Numerous top of the line and premium optic manufacturers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It provides protection for the exterior surfaces of the Steiner glass lens so the water particles can not bind to it or develop surface tension. The outcome is that the water beads sheet off of the scope to maintain a clear, water free sight picture.
Glass Installation Choices
Mounting solutions for scopes are available in a few choices. There are the basic scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also usually come in quick release versions which use manual levers which enable rifle operators to quickly mount and remove the optics.
Hex Key Rifle Scope Rings
Standard, clamp-on design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use a pair of individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This form of scope mount is great for rifles which need to have a long lasting, unfailing mount which will not change regardless of just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you want for a specialized scope setup on a far away scouting or competitors long gun which will almost never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the mount’s screws to keep the hex screws from backing out after they are installed safely in place. An example of these rings are the 30mm style from Vortex Optics. The set normally costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. If they all use a similar style mount, a number of scopes can often be switched in the field. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top type Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving precision. These kinds of mounts come in practical for shooting platforms which are carried a lot, to take off the scope glass from the rifle for protection, or for optics which are chosen for use between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
What to Know About Rifle Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and creating residue inside of the scope tube. The majority of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Rifle Optic Tubes
Another part of preventing the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this area is currently occupied by the gas, the optic is less influenced by temp shifts and pressure differences from the outside environment which may potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to look for.
