What You Need to Know About Scopes
Rifle scopes allow you to precisely align a rifle at various targets by aligning your eye with the target at range. They do this through zoom using a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of numerous environmental considerations like wind and elevation increases to account for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will land 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. A lot of modern-day rifle scopes and optics have about eleven parts which are located inside and on the exterior of the optic. These parts include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other elements. See all eleven parts of a scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Considering the best type of rifle optic is based around what type of shooting you plan to do.
Info About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This induces the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the identical tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who have an idea for their aim point “hold over” and “lead” correlations for their firearm
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane scopes (SFP) include 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.
- Far away kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and spaces
- Shooters who would like a clearer optic sight picture with less area used up by the enlarged FFP reticle
Details on Rifle Scope Magnification
The measure of scope zoom you need depends on the type of shooting you intend to do. Pretty much every style of rifle optic provides some level of zoom. The amount of magnification a scope gives is identified by the size, thickness, and curvatures of the lens glass within the rifle scope. The zoom of the optic is the “power” of the opic. This signifies what the shooter is checking out through the scope is amplified times the power factor of what can normally be seen by human eyes.
Info About Fixed Single Power Lens Scopes
A single power rifle scope and optic comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not adjust since it is a set power scope.
Adjustable Power Lens Glass Facts
Variable power rifle scopes can be tweaked between magnified levels. The power adjustment is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
Rifle Optic Power and Ranges
Here are some advised scope powers and the distances where they could be efficiently used. Consider that higher power scopes and optics will not be as practical as lower magnification level glass since too much magnification can be a detractor. The same idea applies to longer distances where the shooter needs to have enough power to see precisely where to best aim the rifle.
Scope Lens Covering
All modern-day rifle optic and scope lenses are coated. There are different types and qualities of glass finishes. When shopping for luxury rifle optical devices, Lens covering can be an essential aspect of a rifle. The glass lenses are one of the most essential pieces of the scope due to the fact that they are what your eye sees through while sighting a rifle in on the point of impact. The coating on the lenses safeguards the lens exterior and also improves anti glare capabilities from excess sunrays and color recognition.
HD Versus ED Lenses
Some scope makers also use “HD” or high-definition lens coverings which use different processes, chemicals, polarizations, and aspects to draw out separate colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Details on Single Finish Versus Multi-Coating
Different optic lenses can also have various finishings applied to them. All lenses generally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while reducing 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 maker and how much you paid for it.
Some scope producers also make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Details on Hydrophobic Coating
Water on an optic’s lens does not improve retaining a clear sight picture through an optic whatsoever. Numerous top of the line or premium optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the surface of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Options for Installing Rifle Scopes on Long Guns
Installing options for scopes come in a few options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different kinds of mounts also typically come in quick release versions which use toss levers which permit rifle operators to rapidly mount and dismount the scopes.
Hex Key Optic Ring Mounting Solutions
Standard, clamp-on design mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These varieties of scope mounts use a pair of independent rings to support the optic, and are made from 7075 T6 billet aluminum which are designed for long distance precision shooting. This type of scope mount is great for rifles which need a durable, unfailing mount which will not move no matter how much the scope is moved about or abuse the rifle takes. These are the style of mounts you should have for a faithful scope system on a far away scouting or competition rifle that will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to prevent the hex screw threads from backing out after they are mounted firmly in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Scope Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Numerous scopes can also be swapped out if they all use a similar design mount. These types of mounts come in handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between several rifles or are situationally focused.
Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by bringing about fogging and producing residue inside of the scope tube. The majority of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Scope Tubes
Another component of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the optic is less altered by temperature shifts and pressure variations from the external environment which might possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
