All About Rifle Glass
Rifle scopes permit you to precisely aim a rifle at different targets by aligning your eye with the target over a distance. They do this through magnification by employing a set of lenses inside the scope. The scope’s positioning can be adjusted to take into account many environmental elements like wind and elevation to account for bullet drop.
The scope’s function is to understand exactly where the bullet will land based upon the sight picture you are viewing with the scope as you line up the scope’s crosshair or reticle with the target. A lot of contemporary rifle scopes and optics have around eleven parts which are found internally and externally on the scope body. These parts include the rifle scope’s body, lenses, windage and elevation turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of rifle scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The type of focal plane an optic has identifies where the reticle or crosshair lies relative to the scopes magnification. It actually implies the reticle is behind or ahead of the magnification lens of the optic. Picking out the most suitable form of rifle scope is dependent on what form of shooting you anticipate undertaking.
About First Focal Plane Optics
Focal plane scopes (FFP) include the reticle in front of the zoom lens. These styles of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where computations are marginal
- Experienced shooters who recognize their aim point “hold over” and “lead” relationships for their long gun
- Shooters who do not mind the reticle is bigger and takes up more visual sight area than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane optics (SFP) feature the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance styles of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots happen within shorter spaces and ranges
- Shooters who like a clearer optic picture with less room taken up by the larger sized FFP reticle
Details on Scope Zoom
The extent of scope magnification you need is based on the form of shooting you desire to do. Just about every type of rifle glass delivers some amount of zoom. The amount of zoom a scope supplies is determined by the dimension, density, and curvatures of the lenses within the rifle optic. The magnification of the scope is the “power” of the opic. This signifies what the shooter is aiming at through the scope is magnified times the power aspect of what can typically be seen by human eyes.
Fixed Power Lens Scopes
A single power rifle optic will have a magnification number designator like 4×32. This means the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate considering that it is a set power scope.
Variable Power Lens Rifle Optic Details
Variable power rifle scopes use variable power levels. The power change is achieved by the power ring part of the scope near the rear of the scope by the eye bell.
Glass Power and Ranges
Here are some suggested scope powers and the ranges where they may be efficiently used. Highly magnified rifle scope glass will not be as efficient as lower magnification level scopes since too much magnification can be a bad thing. The very same idea relates to longer distances where the shooter needs to have increased power to see where to properly aim the rifle at the target.
Optic Lens Finish
All top of the line rifle glass lenses are covered. Lens coating is an important element of a rifle system when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope makers likewise use “HD” or high-definition lens coverings which use various methods, elements, chemicals, and polarizations to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Rifle Scope Lens Finish Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It needs to have a finish put on it so that it will be efficiently usable in many types of environments, degrees of sunshine (full light VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and enhancing multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends on the scope developer and how much money you spent for it. Both the manufacturer and amount are indicators of the lens quality.
Some scope makers also make it a point to specify if their optic lenses are coated or “multi” covered. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in developing the rifle scope.
Optic Lens Anti-water Covering
Water on an optical lens doesn’t improve preserving a clear sight picture through an optic at all. Many top of the line or high-end scope makers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It treats the exterior of the Steiner scope lens so the H2O molecules can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Optics on Firearms
Installing approaches for scopes are available in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually can be found in quick release variations which use throw levers which enable rifle shooters to quickly mount and remove the scopes.
Hex Key Rifle Optic Ring Mounting Solutions
Basic, clamp-on style mounting scope rings use hex head screws to install to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use two individual rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for far away precision shooting. This kind of scope mount is great for rifles which require a long lasting, hard use mount which will not shift despite just how much the scope is moved or abuse the rifle takes. These are the design of mounts you want for a specialized scope system on a reach out and touch someone scouting or interdiction long gun that will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screw threads from backing out after they are installed tightly in place. An example of these rings are the 30mm type from Vortex Optics. The set usually costs around $200 USD
Rifle Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope and connect it to a different rifle. Multiple scopes can even be switched out if they all use a similar design 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 scopes which are used in between several rifles.
Info on Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by triggering fogging and creating residue within the scope’s tube. A lot of optics protect against wetness from getting in the optical tube with a system of sealing O-rings which are water resistant. Usually, these optics can be immersed beneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be sufficient wetness prevention for basic use rifles, unless you plan on taking your rifle sailing and are worried about the scope still functioning if it is submerged in water and you can still recover the rifle.
Gas Purged Scope Tubes
Another part of preventing the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less altered by temp alterations and pressure differences from the outside environment which could 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 look for.
