Rifle Glass Info
Rifle scopes enable you to precisely align a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be dialed in to account for many environmental things like wind speed and elevation increases or decreases to make up for bullet drop.
The scope’s purpose is to help shooters understand precisely 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 intended point of impact. Many modern-day rifle optics have around eleven parts which are found within and outside of the scope body. These optic pieces include the rifle scope’s body, lenses, windage dials, objective focus rings, and other elements. Learn about the eleven parts of rifle optics.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle glass is based on what type of shooting you plan to do.
First Focal Plane Glass
First focal plane scopes (FFP) include the reticle in front of the magnification lens. This induces the reticle to increase in size based upon the level of magnification being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. For example, one tick on a mil-dot reticle at one hundred yards without any “zoom” is still the very same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are low
- Experienced shooters who know their aim point “hold over” and “lead” equations for their long guns
- Shooters who don’t mind the reticle is enlarged and takes up more visual eyesight area than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle to the rear of the magnifying lens. This causes the reticle to stay at the very same dimensions in connection with the amount of zoom being used. The effect is that the reticle dimensions adjust based upon the zoom applied to shoot over longer distances given that the markings represent various increments which vary with the magnification. In the FFP illustration with the SFP scope, the 5x “zoom” 100 yard tick would be 1/5th of the non “zoom” tick measurement. These particular varieties of glass are beneficial for:
- Long distance styles of shooting where shooters have increased time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture with less room taken up by the larger size FFP reticle
The level of scope magnification you require depends upon the form of shooting you like to do. Virtually every kind of rifle glass supplies some degree of zoom. The volume of zoom a scope offers is identified by the size, thickness, and curves of the lens glass inside of the rifle scope. The magnification of the scope is the “power” of the opic. This indicates what the shooter is looking at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Fixed Power Lens Rifle Glass
A single power rifle optic or scope will have a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not fluctuate since it is a fixed power optic.
Adjustable Power Lens Optic Details
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom degree in a format like 2-10×32. These numbers mean the zoom of the scope can be adjusted between 2x and 10x power. This additionally includes the powers in-between 2 and 10. The power adjustment is achieved by employing the power ring part of the scope near the back of the scope by the eye bell piece.
Scope Power Level and Range Correlation
Here are some recommended scope power settings and the distances where they could be efficiently used. Bear in mind that high magnification glass will not be as practical as lower magnification level optics since increased zoom can be a detractor. The very same idea applies to longer distances where the shooter needs enough power to see precisely where to best aim the rifle.
Info on Lens Finish
All top of the line rifle optic lenses are layered. Lens finishing is a crucial element of a rifle’s setup when looking into high end rifle optics and scope equipment.
Info on Glass Lens Coatings – HD Versus ED
Some scope makers likewise use “HD” or high-definition lens coatings which use various processes, polarizations, elements, and chemicals to draw out different colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Finishing Versus Multi-Coating
Various optic lenses can also have various finishes applied to them. All lenses usually have at least some type of treatment or coating used to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while lowering 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 also make it a point to specify if their optic lenses are covered or “multi” covered. This implies the lens has several treatments applied to them. If a lens receives multiple treatments, it can show that a maker is taking several actions to fight various environmental elements like an anti-glare covering, a scratch resistant anti-abrasion coating, followed by a hydrophilic coating. This additionally doesn’t necessarily suggest the multi-coated lens is much better than a single coated lens. Being “better” depends upon the producer’s lens treatment techniques and the quality of components used in developing the rifle glass.
Anti-water Lens Covering
Water on a lens does not assist with preserving a clear sight picture through a scope at all. Lots of top of the line and high-end scope companies will coat their lenses with a hydrophobic or hydrophilic covering.
Optic Mounting Options
Installing solutions for scopes are available in a few options. There are the basic scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally come in quick release variations which use toss levers which permit rifle operators to rapidly mount and remove the scopes.
Rifle Scope Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for long distance accuracy shooting. This type of scope install is great for rifles which require a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Scope Rings
These kinds of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. A wide range of scopes can also be switched out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten solidly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining precision. These types of mounts come in handy for rifles which are transported a lot, to remove the scope from the rifle for protection, or for aiming systems which are adopted between multiple rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It usually costs around $250 USD
About Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. Many scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Details on Glass Tube Gas Purging
Another component of preventing the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the glass is less impacted by temp alterations and pressure variations from the outside environment which may possibly enable water vapor to seep in around the seals to fill the vacuum which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
