What You Need to Know About Rifle Optics
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by making use of a series of lenses within the scope. The scope’s alignment can be adjusted to account for different natural factors like wind and elevation increases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based on the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle optics have around 11 parts which are found internally and on the exterior of the optic. These parts include the rifle scope’s body, lenses, modification dials, focus rings, and other elements. See all eleven parts of a rifle scope.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the best type of rifle scope is based on what type of shooting you plan on doing.
Info on First Focal Plane Glass
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the extent of magnification being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are very little
- Experienced shooters who know their target “hold over” plus “lead” relationships for their rifles
- Shooters who don’t mind the reticle is enlarged and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick.
- Far away styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and distances
- Shooters who desire a clearer optic sight picture without area taken up by the enlarged FFP reticle
Ins and Outs of Glass Zoom
The amount of magnification a scope provides is identified by the size, density, 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 Scopes
A single power rifle scope and optic will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust given that it is a fixed power scope.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power adjustment is achieved by using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Scopes
Here are some recommended scope power levels and the ranges where they may be efficiently used. Highly magnified scopes will not be as useful as lower powered optics because too much magnification can be a bad thing. The same idea goes for longer ranges where the shooter needs adequate power to see where to properly aim the rifle at the target.
Lens Covering for Scopes
All modern rifle scope lenses are coated. There are various types and qualities of glass lens finishes. Lens covering can be an important aspect of a rifle’s setup when looking into high end rifle optics and scope equipment. The glass lenses are one of the most crucial components of the glass because they are what your eye sees through while sighting a rifle in on the target. The coating on the lenses safeguards the lens surface area and even assists with anti glare capabilities from excess sunlight and color profiles.
HD Versus ED Optic Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishings which use different techniques, components, chemicals, and polarizations to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finish Versus Multi-Coating
Various scope lenses can even have various finishes applied to them. All lenses usually have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic assembly. Because the lens isn’t just a raw piece of glass, they require performance enhancing coatings. 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 lots of kinds of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can safeguard the lens from scratches while reducing glare and other less beneficial 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 how much you paid for it.
Some scope makers also make it a point to define if their optic lenses are coated or “multi” covered. This means the lens has had numerous treatments applied to the surfaces. If a lens gets multiple treatments, it can show that a producer is taking several actions to combat different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also does not always mean the multi-coated lens is much better than a single covered lens. Being “better” is dependent on the manufacturer’s lens treatment techniques and the quality of glass used in building the rifle glass.
Anti-water Lens Coverings
Water on a lens doesn’t improve retaining a clear sight picture through a scope at all. Many top of the line or high-end optic producers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface area 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 sheet off of the scope to maintain a clear, water free sight picture.
Rifle Optic Installing Alternatives
Installing options for scopes can be found in a few options. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release versions which use manual levers which allow rifle shooters to quickly mount and remove the glass.
Hex Key Scope Ring Mounting Solutions
Standard, clamp design mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use two separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance accuracy shooting. This type of scope mount is ideal for rifle systems which need a long lasting, rock solid mount which will not shift no matter just how much the scope is moved or jarring the rifle takes. These are the style of mounts you really want to have for a specialized optics system on a reach out and touch someone scouting or competition firearm which will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to stop the hex screw threads from wiggling out after they are installed tightly in place. An example of these rings are the 30mm style made by Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Scope Rings
These types of quick-release rifle scope mounts can be used to rapidly attach and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can also be swapped out if they all use a compatible style mount. These types of mounts are convenient 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.
About Rifle Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day on the range and your expensive optic by triggering fogging and producing residue inside of the scope tube. Many optics protect against moisture from going into the scope tube with a series of sealing O-rings which are waterproof. Generally, these scopes can be submerged beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be sufficient moisture prevention for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle aboard a watercraft and are worried about the optic still working if it falls overboard and you can still find the rifle.
What to Know About Rifle Optic Tube Gas Purging
Another part of preventing the buildup of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already occupied by the gas, the glass is less affected by temperature shifts and pressure differences from the outdoor environment which may potentially permit water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
