Rifle Optic Facts
Rifle scopes enable you to precisely aim a rifle at various targets by lining up your eye with the target at range. They accomplish this through magnification by making use of a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of varied natural things like wind speed and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand precisely where the bullet will hit based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the target. Many modern-day rifle scopes have about 11 parts which are located inside and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, windage turrets, objective focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Scope Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Selecting the optimal type of rifle glass is based around what type of shooting you plan on doing.
First Focal Plane Optic Info
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are minor
- Experienced shooters who have an idea for their aim point “hold over” and “lead” correlations for their long guns
- Shooters who don’t mind the reticle is enlarged and occupies more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. This induces the reticle to stay at the same size in relation to the level of zoom being used. The result is that the reticle measurements evolve based upon the magnification chosen to shoot over lengthier distances since the markings present various increments which change with the zoom level. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick reticle measurement. These types of glass are beneficial for:
- Far away styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most of the shots take place within shorter ranges and spaces
- Shooters who want a clearer optic sight picture without room used up by the enlarged FFP reticle
Optic Zoom
The amount of scope zoom you need on your glass depends upon the type of shooting you desire to do. Almost every type of rifle optic delivers some amount of magnification. The quantity of magnification a scope supplies is identified by the size, thickness, and curves of the lens glass within the rifle scope. The magnification level of the optic is the “power” of the scope. This implies what the shooter is observing through the scope is amplified times the power aspect of what can generally be seen by human eyes.
About Single Power Lens Rifle Glass
A single power rifle scope comes with a magnification number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not fluctuate because it is set from the factory.
About Variable Power Lens Optics
Variable power rifle scopes use enhanced power. The power modification is handled by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Rifle Optics
Here are some suggested scope powers and the distances where they may be successfully used. High power scopes will not be as effective as lower powered rifle scope glass considering too much zoom can be a bad thing. The same goes for longer distances where the shooter needs to have increased power to see precisely where to best aim the rifle.
Lens Covering for Scopes
All present day rifle glass lenses are coated. Lens finishing can be an essential element of a rifle when looking into high end rifle optics and scope equipment.
HD Versus ED Rifle Glass Lens Coatings
Some scope makers likewise use “HD” or high-definition lens coatings which use various procedures, polarizations, chemicals, and aspects to draw out various colors and viewable quality through the lens. Some scope makers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finishing Versus Multi-Coating for Glass
Various scope lenses can also have various finishings applied to them. All lenses generally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic assembly. This is because the lens isn’t simply a raw piece of glass. It becomes part of the carefully tuned optic. It requires a coating to be applied to it so that it will be optimally functional in many types of environments, degrees of sunlight (full VS shaded), and other shooting conditions.
This lens treatment can offer protection to the lens from scratches while reducing glare and other less advantageous 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 manufacturers similarly make it a point to specify if their optic lenses are layered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in developing the rifle scope.
Anti-water Lens Finish
Water on an optic’s lens does not support maintaining a clear sight picture through a scope at all. Many top of the line and high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It deals with the exterior surfaces of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to preserve a clear, water free sight picture.
Scope Installing Alternatives
Mounting options for scopes come in a few choices. There are the standard scope rings which are separately installed to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also usually can be found in quick release versions which use toss levers which enable rifle shooters to rapidly mount and dismount the scopes.
Scope Mounting Solutions with Hex Key Rings
Basic, clamp style mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mounting rails on the tops of rifles. These types of scope mounts use a pair of individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are designed for far away accuracy shooting. This type of scope mount is ideal for rifles which need a durable, rock solid mount which will not change regardless of just how much the scope is moved or abuse the rifle takes. These are the style of mounts you want for a dedicated scope setup on a reach out and touch someone hunting or hard target interdiction long gun that will seldom need to be modified or adjusted. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to keep the hex screw threads from wiggling out after they are installed tightly in place. An example of these rings are the 30mm style made by Vortex Optics. The set typically costs around $200 USD
Optic Mounting Solutions with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly remove a scope from a rifle and reattach it to a different rifle. Multiple scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach firmly to a flat top design Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining the original sighting settings. These types of mounts come in convenient for rifles which are carried a lot, to take off the scope glass from the rifle for protection, or for sight systems which are chosen for use between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
What to Know About Rifle Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can destroy a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes avoid moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Glass Tubes
Another element of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the optic is less altered by temperature level shifts and pressure differences from the outdoor environment which may possibly enable 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.
