What You Need to Know About Glass
Rifle scopes enable you to exactly aim a rifle at different targets by aligning your eye with the target over a distance. They do this through magnifying the target by using a set of lenses inside the scope. The scope’s positioning can be adapted to take into account numerous natural considerations like wind and elevation increases or decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are viewing with the optic as you align the scope’s crosshair or reticle with the target. Many modern rifle scopes and optics have about 11 parts which are found internally and outside of the optic. These optic pieces consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The style of focal plane a scope has determines where the reticle or crosshair is located relative to the scopes zoom. It actually means the reticle is situated behind or before the magnification lens of the optic. Looking for the very best type of rifle glass depends upon what style of shooting or hunting you anticipate doing.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the level of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where computations are minimal
- Experienced shooters who know their aim point “hold over” as well as “lead” correlations for their long gun
- Shooters who don’t mind the reticle is bigger and takes up more visual eyesight space than a SFP reticle
Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the magnification 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 reticle measurement.
- Far away types of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots take place within shorter ranges and distances
- Shooters who like a clearer optic picture without area used up by the enlarged FFP reticle
Ins and Outs of Rifle Glass Magnification
The quantity of magnification a scope offers 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 Power Lens Rifle Glass
A single power rifle optic comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not change considering that it is a set power scope.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom amount in a configuration like 2-10×32. These numbers suggest the magnification of the scope can be adjusted between 2x and 10x power. This additionally involves the powers in-between 2 and 10. The power adjustment is achieved by working with the power ring component of the scope near the rear of the scope by the eye bell.
The Power Level and Range Correlation of Scopes
Here are some suggested scope power levels and the distances where they could be efficiently used. Highly magnified rifle scope glass will not be as efficient as lower magnification level glass given that too much zoom can be a negative aspect depending on your shooting distance. The very same idea relates to longer distances where the shooter needs to have enough power to see where to best aim the rifle at the target.
Scope Lens Finishing
All contemporary rifle optic lenses are covered. Lens finish is a crucial element of a rifle system when thinking about high end rifle optics and scope setups.
HD Versus ED Lenses
Some scope brands likewise use “HD” or high-definition lens coatings which use different methods, polarizations, aspects, and chemicals to draw out separate colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Covering Versus Multi-Coating
Various optic lenses can likewise have various finishes used to them. All lenses usually have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can protect the lens from scratches while minimizing 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 producer and how much you paid for it.
Some scope makers also make it a point to specify if their optic lenses are layered or “multi” coated. This indicates the lens has had numerous treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a producer is taking several actions to combat different natural elements like an anti-glare coating, a scratch resistant anti-abrasion finish, followed by a hydrophilic covering. This additionally doesn’t always indicate the multi-coated lens is better than a single layered lens. Being “better” hinges on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle optic.
Glass Lens Anti-water Finishing
Water on an optic’s lens does not assist with preserving a clear sight picture through an optic in any way. Numerous top of the line and high-end optic manufacturers will coat their lenses with a hydrophilic or hydrophobic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It provides protection for the surface of the Steiner optic lens so the H2O particles can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Scope Installing Choices
Installing solutions for scopes can be found in a few choices. There are the basic scope rings which are separately installed to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally come in quick release versions which use manual levers which enable rifle operators to quickly install and dismount the scopes.
Hex Key Rifle Glass Rings
Standard, clamp design mounting optic rings use hex head screws to install to the flattop design Picatinny scope mount rails on rifles. These styles of scope mounts use double detached rings to support the scope, and are usually constructed from 7075 T6 billet aluminum which are made for far away precision shooting. This kind of scope mount is great for rifle systems which need a resilient, hard use mount which will not move no matter how much the scope is moved about or jarring the rifle takes. These are the design of mounts you want for a specialized scope setup on a long distance scouting or competitors long gun which will hardly ever need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the scope mount’s screws to prevent the hex screws from wiggling out after they are mounted firmly in place. An example of these rings are the 30mm style from Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Numerous scopes can even be switched out if they all use a compatible style mount. These types of mounts come in handy for long guns which are transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used in between numerous rifles.
Sealing and Gas Purging for Rifle Optic Tubes
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. The majority of scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Optic Tubes
Another component of preventing the accumulation of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is already taken up by the gas, the optic is less impacted by temp shifts and pressure variations from the outside environment which could potentially allow water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
