Optic Facts
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target at range. They do this through magnification by using a series of lenses within the scope. The scope’s alignment can be dialed in to take into account different natural factors like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are viewing via the optic as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle scopes and optics have around 11 parts which are found within and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other elements. See all eleven parts of a rifle optical system.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the optimal type of rifle glass is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These types of scopes are beneficial for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are low
- Experienced shooters who understand their target “hold over” as well as “lead” correlations for their weapon
- Shooters who don’t mind the reticle is enlarged and requires more visual eyesight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Far away kinds of shooting where shooters have increased time to make ballistic computations
- Shooting where most of the shots occur within shorter proximities and ranges
- Shooters who like a clearer optic sight picture without room taken up by the larger sized FFP reticle
Ins and Outs of Rifle Optic Zoom
The measure of scope magnification you need on your optic depends on the style of shooting you intend to do. Practically every kind of rifle optic provides some level of magnification. The amount of magnification a scope provides is determined by the size, thickness, and curves of the lenses inside of the rifle scope. The magnification level of the optic is the “power” of the glass. This signifies what the shooter is aiming at through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Fixed Single Power Lens Rifle Optic Facts
A single power rifle optic and scope uses a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not adjust since it is set from the factory.
Variable Power Lens Glass
Variable power rifle scopes use variable power levels. The power adjustment is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Glass
Here are some recommended scope powers and the distances where they could be efficiently used. Highly magnified glass will not be as useful as lower magnification rifle scope glass because too much zoom can be a bad thing. The same concept relates to extended distances where the shooter needs to have increased power to see precisely where to properly aim the rifle at the target.
Glass Lens Covering
All modern rifle optic and scope lenses are coated. There are various types and qualities of lens coverings. When researching luxury rifle targeting devices, Lens finishing can be an important element of defining the rifle’s capability. The lenses are one of the most significant components of the scope given that they are what your eye looks through while sighting a rifle in on the point of impact. The coating on the lenses protects the lens surface area and even assists with anti glare from refracted sunshine and color exposure.
HD Versus ED Lens Coatings
Some optic makers will also use “HD” or high-def glass coatings which employ various processes, polarizations, chemicals, and elements to enhance separate colors and viewable target definition through the lens. This high-def finish is commonly used with higher density glass which lowers light’s opportunity to refract by means of the lens glass. Some scope makers use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be visible over things with defined outlines as light hits the item from specific angles.
Single Covering Versus Multi-Coating for Scopes
Different scope lenses can even have various finishings applied to them. All lenses typically have at least some kind of treatment or finish applied to them before being used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It becomes part of the carefully tuned optic. It must have a finish put on it so that it will be optimally functional in numerous kinds of environments, degrees of light (full light VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing 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 maker and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the producer’s lens treatment technology and the quality of products used in building the rifle scope.
Hydrophobic Optic Lens Finishing
Water on an optic’s lens doesn’t improve preserving a clear sight picture through a scope whatsoever. Many top of the line or high-end optic producers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner glass lens so the H2O molecules can not bind to it or create surface tension. The outcome is that the water beads sheet off of the scope to preserve a clear, water free sight picture.
Choices for Installing Rifle Glass on Firearms
Installing approaches for scopes can be found in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also usually are made in quick release variations which use manual levers which enable rifle operators to rapidly install and dismount the glass.
Hex Key Glass Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of 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 created for long distance accuracy shooting. This type of scope mount is excellent for rifles which are in need of a long lasting, rock solid mount which will not shift no matter how much the scope is moved about or jarring the rifle takes. These are the type of mounts you want for a specialized scope system on a far away scouting or tournament rifle which will rarely need to be changed or adjusted. Blue 242 Loctite threadlocker can additionally be used to keep the hex screws from wiggling out after they are mounted tightly in position. An example of these rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These kinds of quick-release rifle scope mounts can be used to quickly take off 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 complementary designed mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten firmly 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 types of mounts are useful and handy for rifles which are hauled around a lot, to take off the glass from the rifle for protection, or for aiming systems which are chosen for use in between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by triggering fogging and developing 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 water resistant.
Gas Purged Rifle Glass Tubes
Another part of preventing the accumulation of wetness inside of the rifle optic’s tube is filling the tube with a gas like nitrogen. Since this space is already occupied by the gas, the optic is less affected by climate shifts and pressure differences from the external environment which could possibly permit water vapor to permeate in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to look for.
