All About Rifle Optics
Rifle scopes allow you to precisely align a rifle at various targets by lining up your eye with the target at range. They do this through magnifying the target by using a set of lenses inside the scope. The scope’s alignment can be dialed in to take into account separate environmental things like wind and elevation increases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will land based upon the sight picture you are seeing using the scope as you align the scope’s crosshair or reticle with the target. The majority of contemporary rifle optics have about 11 parts which are found within and on the exterior of the optic. These parts include the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. See all eleven parts of an optic.
About Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the optimal type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Scopes
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These styles of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where calculations are minimal
- Experienced shooters who understand their target “hold over” and “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. This causes the reticle to remain at the very same overall size in connection with the amount of magnification being used. The final result is that the reticle dimensions change based upon the magnification used to shoot over longer ranges considering the reticle measurements represent distinct increments which fluctuate with the magnification. 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 are useful for:
- Long distance types of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who select a clearer optic picture without room used up by the larger size FFP reticle
Optic Zoom
The measure of scope magnification you need on your glass depends on the sort of shooting you like to do. Almost every kind of rifle optic supplies some level of magnification. The amount of magnification a scope delivers is identified by the diameter, thickness, and curves of the lens glass inside of the rifle optic. The magnification of the optic is the “power” of the scope. This suggests what the shooter is observing through the scope is amplified times the power factor of what can usually be seen by human eyes.
Single Power Lens Rifle Scopes
A single power rifle scope will have a magnification number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of scope can not adjust because it is a set power scope.
Variable Power Lens Scope Info
Variable power rifle scopes have adjustable power. These types of scopes will list the zoom degree in a format like 2-10×32. These numbers mean the zoom of the scope can be adjusted in between 2x and 10x power. This also utilizes the power levels in-between 2 and 10. The power shift is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range Correlation of Rifle Glass
Here are some recommended scope power settings and the ranges where they may be effectively used. Highly magnified optics will not be as efficient as lower powered scopes given that too much magnification can be a bad thing. The exact same idea applies to longer ranges where the shooter needs to have adequate power to see exactly where to properly aim the rifle at the target.
Info on Glass Lens Coverings
All present day rifle scope and optic lenses are coated. Lens coating is a vital aspect of a rifle’s setup when thinking about high end rifle optics and scope setups.
HD Versus ED Lenses
Some scope producers likewise use “HD” or high-definition lens coatings which use various techniques, chemicals, polarizations, and aspects to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Coating Versus Multi-Coating
Various optic lenses can also have various coverings applied to them. All lenses normally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. Due to the fact that the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in lots of kinds of environments, degrees of light (full VS shade), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope producer and how much you paid for it.
Some scope producers likewise make it a point to define if their optic lenses are coated or “multi” coated. This implies the lens has had several treatments applied to the surfaces of the glass. If a lens gets several treatments, it can indicate that a maker is taking several steps to combat various natural factors like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also doesn’t always imply the multi-coated lens will perform better than a single covered lens. Being “better” depends upon the manufacturer’s lens treatment innovation and the quality of components used in creating the rifle optic.
Hydrophobic Lens Covering
Water on an optic’s lens doesn’t assist with maintaining a clear sight picture through an optic whatsoever. Lots of top of the line or premium optic producers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the surface area of the Steiner scope lens so the water molecules can not bind to it or develop surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Scope Mounting Options
Installing approaches for scopes can be found in a few options. There are the standard scope rings which are individually installed to the optic and one-piece mounts which cradle the scope. These different types of mounts also usually are made in quick release versions which use manual levers which allow rifle shooters to rapidly install and remove the glass.
Hex Key Rifle Optic Ring Mounting Solutions
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on rifles. These types of scope mounts use two different rings to support the optic, and are often made from 7075 T6 billet aluminum which is designed for long range precision shooting. This type of scope install is great for rifles which require a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly connect and detach a scope from a rifle before reattaching 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 handy for long guns which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles or are situationally focused.
Rifle Scope Tube Sealing and Gas Purging
Moisture inside your rifle scope can destroy a day of shooting and your pricey optic by inducing fogging and developing residue inside of the scope tube. The majority of optics prevent humidity from entering the optical tube with a system of sealing O-rings which are waterproof. Typically, these water resistant optics can be immersed within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough moisture content prevention for standard use rifles, unless you plan on taking your rifle on a boat and are worried about the optic still working if it falls overboard and you can still find the gun.
Gas Purged Rifle Optic Tubes
Another element of avoiding the buildup of moisture inside of 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 optic is less impacted by temperature shifts and pressure variations from the outdoor environment which may possibly permit water vapor to seep in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
