What You Need to Know About Glass
Rifle scopes allow you to specifically aim a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by utilizing a set of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of various natural aspects like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern rifle scopes and optics have about 11 parts which are arranged internally and externally on the scope body. These optic pieces consist of the rifle scope’s body, lenses, modification dials or turrets, focus rings, and other elements. Learn about the eleven parts of rifle scopes.
About Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane an optic has identifies where the reticle or crosshair lies in regard to the scopes magnifying adjustments. It simply suggests the reticle is located behind or before the magnification lens of the scope. Picking out the most ideal kind of rifle optic is dependent on what kind of shooting you anticipate doing.
First Focal Plane Optic Facts
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This causes the reticle to increase in size based on the amount of magnification being used. The outcome is that the reticle measurements are the same at the magnified range as they are at the non amplified range. For example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting scenarios where computations are very little
- Experienced shooters who know their target “hold over” and also “lead” equations for their rifles
- Shooters who do not mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane glass (SFP) feature the reticle behind the magnifying lens. This triggers the reticle to remain at the same dimensions in connection with the volume of zoom being used. The final result is that the reticle dimensions adjust based on the magnification applied to shoot over greater ranges considering the reticle measurements present various increments which differ with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement. These styles of optics work for:
- Far away forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who want a clearer optic sight picture without room taken up by the bigger FFP reticle
Rifle Glass Zoom
The level of scope zoom you need depends upon the type of shooting you intend to do. Pretty much every style of rifle scope delivers some degree of zoom. The amount of zoom a scope offers is determined by the size, thickness, and curves of the lens glass within the rifle scope. The zoom of the optic is the “power” of the scope. This indicates what the shooter is observing through the scope is amplified times the power element of what can generally be seen by human eyes.
Info on Fixed Power Lens Rifle Scopes
A single power rifle scope or optic uses a zoom number designator like 4×32. This means the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change considering that it is a set power scope.
Adjustable Power Lens Rifle Glass
Variable power rifle scopes can be adjusted between magnification increments. These types of scopes will note the magnification degree in a format such as 2-10×32. These numbers mean the magnification of the scope can be set in between 2x and 10x power. This additionally utilizes the power levels in-between 2 and 10. The power manipulation is achieved by making use of the power ring component of the scope near the back of the scope by the eye bell.
Power and Range
Here are some recommended scope power settings and the ranges where they can be successfully used. Keep in mind that higher magnification optics will not be as efficient as lower powered scope and optics due to the fact that too much zoom can be a bad thing. The same goes for extended distances where the shooter needs enough power to see exactly where to best aim the rifle at the target.
Glass Lens Finish
All top teir rifle optic and scope lenses are covered. Lens finish is an essential element of a shooting platform when thinking about high end rifle optics and scope systems.
ED Versus HD Scopes
Some scope manufacturers also use “HD” or high-definition lens finishes which use different processes, polarizations, elements, and chemicals to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Different optic lenses can likewise have different finishings used to them. All lenses typically have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while decreasing glare and other less useful 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 likewise make it a point to specify if their optic lenses are coated or “multi” coated. This implies the lens has had several treatments applied to the surfaces. If a lens gets numerous treatments, it can establish that a company is taking multiple actions to fight different natural elements like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This additionally does not necessarily mean the multi-coated lens is much better than a single coated lens. Being “much better” depends upon the manufacturer’s lens treatment techniques and the quality of products used in building the rifle scope.
Rifle Optic Lens Anti-water Covering
Water on a scope’s lens doesn’t support retaining a clear sight picture through a scope at all. Many top of the line or high-end scope producers 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 deals with the surface of the Steiner scope lens so the water molecules can not bind to it or produce surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Alternatives for Mounting Optics on Firearms
Mounting options for scopes are available in a couple of options. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various types of mounts also normally come in quick release versions which use throw levers which permit rifle shooters to quickly install and dismount the glass.
Hex Key Scope Ring Mounts
Basic, clamp-on type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These forms of scope mounts use two individual rings to support the scope, and are normally constructed from 7075 T6 billet aluminum or similar materials which are designed for long distance precision shooting. This kind of scope mount is great for rifle systems which need to have a durable, hard use mount which will not change no matter how much the scope is moved about or abuse the rifle takes. These are the design of mounts you want for a devoted optics setup on a reach out and touch someone hunting or competitors rifle that will hardly ever need to be altered or adjusted. Blue 242 Loctite threadlocker can additionally be used on the mount screws to protect against the hex screw threads from wiggling out after they are installed tightly in position. An example of these rings are the 30mm style made by the Vortex Optics company. The set typically costs around $200 USD
Glass Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly detach a scope and connect it to a different rifle. Multiple scopes can even be swapped out if they all use a compatible design mount. These types of mounts are convenient for rifles which are transferred a lot, to remove the optic from the rifle for protecting the scope, or for optics which are used in between several rifles or are situationally focused.
What to Know About Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. Most scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Optic Tubes
Another part of avoiding the accumulation of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the scope is less altered by temperature level alterations and pressure differences from the external environment which might potentially enable water vapor to permeate in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a good rifle scope to look for.
