Rifle Glass Info
Rifle scopes permit you to specifically align a rifle at various targets by lining up your eye with the target at range. They do this through magnification by utilizing a series of lenses inside the scope. The scope’s alignment can be adjusted for the consideration of numerous ecological things like wind speed and elevation to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will hit based on the sight picture you are viewing through the optic as you line up the scope’s crosshair or reticle with the target. The majority of contemporary rifle optics have about 11 parts which are arranged internally and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other elements. Learn about the eleven parts of optics.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Picking the finest type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Optic Facts
First focal plane glass (FFP) feature the reticle ahead of the zoom lens. This causes the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non magnified range. For example, one tick on a mil-dot reticle at 100 yards without “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where estimations are low
- Experienced shooters who know their target “hold over” and also “lead” equations for their firearm
- Shooters who do not mind the reticle is bigger and requires more visual sight space than a SFP reticle
Second Focal Plane Optics
Second focal plane scopes (SFP) come with the reticle behind the magnification 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.
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who choose a clearer optic sight picture with less area used up by the enlarged FFP reticle
Optic Magnification
The quantity of zoom a scope supplies is figured out by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
About Fixed Single Power Lens Glass
A single power rifle scope uses a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not adjust considering that it is fixed.
Variable Power Lens Rifle Glass Info
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification level in a configuration like 2-10×32. These numbers indicate the magnification of the scope could be adjusted in between 2x and 10x power. This also utilizes the powers in-between 2 and 10. The power adaptation is achieved by applying the power ring part of the scope near the rear of the scope by the eye bell piece.
The Power and Range Correlation of Optics
Here are some suggested scope powers and the ranges where they may be effectively used. Bear in mind that high power optics and scopes will not be as practical as lower magnification level optics due to the fact that excessive magnification can be a detractor. The exact same concept goes for longer distances where the shooter needs to have increased power to see precisely where to properly aim the rifle.
Optic Lens Finish
All state-of-the-art rifle optic and scope lenses are coated. Lens covering is a significant aspect of a shooting system when buying high end rifle optics and scope equipment.
HD Versus ED Lens Coatings
Some scope manufacturers also use “HD” or high-definition lens finishings which use different processes, polarizations, chemicals, and components to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Glass Lens Coating Versus Multi-Coating
Various optic lenses can also have different finishes used to them. All lenses generally have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can protect the lens from scratches while lowering glare and other less beneficial things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope producer and just how much you spent for it. Both the make and cost are indicators of the lens quality.
Some scope producers also make it a point to specify if their optic lenses are covered or “multi” coated. This suggests the lens has had several treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can indicate that a manufacturer is taking multiple steps to combat various environmental factors like an anti-glare finish, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This additionally doesn’t necessarily mean the multi-coated lens is much better than a single covered lens. Being “better” depends upon the maker’s lens treatment solutions and the quality of glass used in building the rifle optic.
Anti-water Lens Finishes
Water on an optic’s lens does not support retaining a clear sight picture through a scope at all. Numerous top of the line and high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the exterior surfaces of the Steiner scope lens so the H2O molecules can not bind to it or create surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.
Glass Installing Options
Installing approaches for scopes are available in a couple of choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally come in quick release versions which use manual levers which permit rifle operators to rapidly mount and dismount the optics.
Optic Mounts with Hex Key Rings
Basic, clamp-on type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on the tops of rifles. These forms of scope mounts use double separate rings to support the optic, and are normally made from 7075 T6 billet aluminum which are designed for far away accuracy shooting. This type of scope mount is exceptional for rifle systems which need a durable, rock solid mount which will not change no matter how much the scope is moved or jarring the rifle takes. These are the type of mounts you should get for a specialized optics system on a far away hunting or tournament rifle which will almost never need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to stop the hex screw threads from wiggling out after they are installed tightly in position. An example of these mounting rings are the 30mm type from the Vortex Optics brand. The set normally costs around $200 USD
Quick-Release Cantilever Optic Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts are convenient for rifles which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used in between multiple rifles.
Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope tube. The majority of scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Info on Optic Tube Gas Purging
Another component of preventing the buildup of moisture inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the scope is less impacted by temperature alterations and pressure differences from the external environment which could possibly allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to seek out.
