Information Rifle Optics
Rifle scopes enable you to specifically align a rifle at different targets by lining up your eye with the target at range. They accomplish this through magnifying the target by utilizing a series of lenses inside the scope. The scope’s positioning can be adapted for consideration of separate ecological factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based on the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. The majority of modern-day rifle scopes have around eleven parts which are arranged inside and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, windage and elevation turrets, focus rings, and other components. Learn about the eleven parts of rifle glass.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the perfect type of rifle scope is based on what type of shooting you plan to do.
First Focal Plane Scope Details
First focal plane scopes (FFP) come with the reticle ahead of the magnifying lens. This induces the reticle to increase in size based upon the extent of zoom being used. The result is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. As an example, one tick on a mil-dot reticle at 100 yards with no “zoom” is still the corresponding tick at one hundred yards using 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” correlations for their long gun
- Shooters who don’t mind the reticle is bigger and uses up more visual eyesight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance styles of shooting where shooters have extra time to make ballistic computations
- Shooting where most shots take place within much shorter ranges and proximities
- Shooters who choose a clearer optic sight picture with less space used up by the larger size FFP reticle
Magnification for Scopes
The quantity of scope zoom you need on your scope depends on the kind of shooting you choose to do. Almost every kind of rifle optic offers some level of zoom. The level of magnification a scope offers is established by the size, density, and curves of the lens glass inside of the rifle optic. The magnification of the scope is the “power” of the opic. This signifies what the shooter is aiming at through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Power Lens Rifle Glass Info
A single power rifle optic and scope comes with a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of scope can not adjust because it is a fixed power scope.
Adjustable Power Lens Rifle Scopes
Variable power rifle scopes can be modified between magnified settings. The power change is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power and Range of Scopes
Here are some advised scope power levels and the distances where they could be effectively used. Highly magnified optics will not be as effective as lower magnification level optics considering too much zoom can be a bad thing. The same concept goes for longer ranges where the shooter needs to have adequate power to see where to best aim the rifle.
Scope Lens Coating
All state-of-the-art rifle glass lenses are layered. Lens coating is an essential aspect of a rifle’s setup when looking into high end rifle optics and scope equipment.
HD Versus ED Lenses
Some glass suppliers even use “HD” or high-def glass finishings that apply various procedures, aspects, chemical substances, and polarizations to draw out different colors and viewable definition through the lens. This high-def coating is often used with greater density lens glass which decreases light’s potential to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration which is similarly called color distortion or fringing. Chromatic aberration is often obvious over things with hard outlines as light hits the object from various angles.
Glass Lens Single Finish Versus Multi-Coating
Different optic lenses can even have different coverings applied to them. All lenses typically have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic. This is since the lens isn’t just a raw piece of glass. It becomes part of the carefully tuned optic. It must have a finish put on it so that the lens will be efficiently usable in numerous types of environments, degrees of light (full light VS shaded), and other shooting conditions.
Single covered lenses have a treatment applied to them which is generally a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while lowering glare and other less helpful things experienced in the shooting environment while sighting in with the optic. The quality of a single covered lens depends upon the scope developer and how much you spent on it. The scope’s maker and cost are indicators of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are covered or “multi” covered. This suggests the lens has had numerous treatments applied to the surfaces of the glass. If a lens receives numerous treatments, it can prove that a company is taking numerous steps to fight different natural elements like an anti-glare finish, a scratch resistant anti-abrasion covering, followed by a hydrophilic coating. This additionally doesn’t necessarily suggest the multi-coated lens will perform better than a single coated lens. Being “much better” depends on the producer’s lens treatment solutions and the quality of components used in building the rifle scope.
Hydrophobic Covering for Rifle Optics
Water on a scope’s lens doesn’t assist with keeping a clear sight picture through an optic in any way. Numerous top of the line or high-end scope producers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It provides protection for the exterior of the Steiner scope lens so the water molecules can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to preserve a clear, water free sight picture.
Glass Installing Options
Installing options for scopes are available in a couple of choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually come in quick release versions which use manual levers which enable rifle operators to rapidly mount and dismount the scope.
Hex Key Rifle Scope Rings
Standard, clamp style mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on rifles. These kinds of scope mounts use two independent rings to support the scope, and are usually constructed from 7075 T6 billet aluminum or similar materials which are made for far away accuracy shooting. This kind of scope mount is great for rifle systems which need to have a long lasting, rock solid mount which will not move despite how much the scope is moved or abuse the rifle takes. These are the type of mounts you should have for a faithful optics system on a far away scouting or competition long gun that will pretty much never need to be modified or adjusted. Blue 242 Loctite threadlocker can also be used to prevent the hex screw threads from backing out after they are installed firmly in place. An example of these mounting rings are the 30mm type made by the Vortex Optics brand. The set typically costs around $200 USD
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly attach and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can even be swapped out if they all use a similar design mount. These types of mounts are handy for long guns which are carried a lot, to remove the optic from the rifle for protecting the scope, or for scopes which are used between several rifles.
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle scope can destroy a day on the range and your highly-priced optic by causing fogging and making residue inside of the scope tube. Many scopes protect against humidity from going into the scope tube with a system of sealing O-rings which are waterproof. Generally, these scopes can be immersed underneath 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity avoidance for conventional use rifles, unless you plan on taking your rifle on a boat and are concerned about the optic still working if it is submerged in water and you can still rescue the rifle.
Details on Glass Tube Gas Purging
Another component of avoiding the accumulation of moisture inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less altered by condition changes and pressure differences from the outdoor environment which may possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to look for.
