Info About Rifle Optics
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target at range. They do this through magnifying the target by using a set of lenses inside the scope. The scope’s alignment can be adjusted to take into account many environmental aspects like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will hit based upon the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the intended target. Many modern-day rifle scopes and optics have around 11 parts which are located internally and externally on the optic. These parts consist of the rifle scope’s body, lenses, adjustment turrets, focus rings, and other components. Learn about the eleven parts of glass.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the finest type of rifle glass is based around what type of shooting you plan on doing.
Info on First Focal Plane Scopes
First focal plane optics (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based on the extent of zoom being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non amplified distance. For instance, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where estimations are small
- Experienced shooters who know their aim point “hold over” and “lead” ratios for their weapon
- Shooters who do not mind the reticle is bigger and occupies more visual sight room than a SFP reticle
Second Focal Plane Scope Details
Second focal plane scopes (SFP) feature the reticle behind the magnifying lens. This triggers the reticle to remain at the same dimensions relative to the quantity of magnification being used. The final result is that the reticle measurements adjust based upon the magnification employed to shoot over longer ranges since the reticle measurements represent various increments which vary with the zoom level. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These varieties of glass work for:
- Far away kinds of shooting where shooters have more time to make ballistic computations
- Shooting where most shots occur within shorter spaces and ranges
- Shooters who select a clearer optic sight picture with less room used up by the larger sized FFP reticle
Magnification for Scopes
The quantity of scope zoom you need is based on the kind of shooting you like to do. Practically every kind of rifle scope offers some degree of zoom. The level of zoom a scope gives is established by the dimension, thickness, and curves of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the opic. This signifies what the shooter is checking out through the scope is magnified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Rifle Scope Info
A single power rifle optic comes with 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 magnification of this type of optic can not fluctuate because it is a set power scope.
Adjustable Power Lens Glass Info
Variable power rifle scopes use enhanced power. The power adjustment is accomplished by using the power ring part of the scope near the rear of the scope by the eye bell.
Optic Power Level and Ranges
Here are some recommended scope power levels and the ranges where they may be efficiently used. High power optics will not be as efficient as lower powered scopes since too much magnification can be a bad thing. The same applies to longer ranges where the shooter needs to have adequate power to see precisely where to properly aim the rifle at the target.
Lens Coating for Optics
All top of the line rifle scope and optic lenses are layered. Lens finish is a vital aspect of a rifle system when looking at high end rifle optics and scope equipment.
Details on Rifle Optic Lens Coatings – HD Versus ED
Some optic suppliers also use “HD” or high-definition glass coatings which take advantage of various procedures, chemicals, aspects, and polarizations to extract a wide range of color ranges and viewable target definition through lenses. This HD coating is normally used with increased density lens glass which decreases light’s chance to refract through the lens glass. Some scope makers use “HD” to describe “ED” suggesting extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable over objects with defined shapes as light hits the object from various angles.
Single Finishing Versus Multi-Coating
Various optic lenses can also have various finishes applied to them. All lenses typically have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing 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 producer and just how much you spent on it. Both the manufacturer and amount are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” coated. This means the lens has had several treatments applied to the surfaces. If a lens gets several treatments, it can show that a manufacturer is taking multiple actions to combat different natural factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also does not always imply the multi-coated lens is much better than a single covered lens. Being “much better” depends upon the manufacturer’s lens treatment innovation and the quality of components used in constructing the rifle optic.
Hydrophobic Lens Finish
Water on an optic’s lens does not improve retaining a clear sight picture through a scope whatsoever. Many top of the line or premium scope makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior of the Steiner scope lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Options for Mounting Scopes on Firearms
Mounting options for scopes can be found in a couple of options. There are the standard scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use toss levers which allow rifle shooters to quickly mount and dismount the scopes.
Hex Key Scope Rings
Basic, clamp-on design mounting optic rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These styles of scope mounts use double separate rings to support the scope, and are made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This form of scope mount is very good for rifles which are in need of a durable, rock solid mount which will not move despite just how much the scope is moved about or jarring the rifle takes. These are the type of mounts you really want to have for a devoted optics system on a far away hunting or interdiction rifle which will rarely need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used to prevent the hex screw threads from wiggling out after they are mounted securely in position. An example of these rings are the 30mm style from the Vortex Optics brand. The set generally costs around $200 USD
Quick-Release Cantilever Optic Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and take off a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be swapped out if they all use a compatible style mount. These types of mounts are handy for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
What to Know About Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your pricey optic by causing fogging and developing residue inside of the scope tube. The majority of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Rifle Optic Gas Purging
Another element of avoiding the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is already occupied by the gas, the glass is less impacted by condition changes and pressure distinctions from the outdoor environment which might potentially enable water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
