Rifle Optic Information
Rifle scopes allow you to specifically aim a rifle at different targets by lining up your eye with the target over a distance. They do this through magnifying the target using a series of lenses within the scope. The scope’s positioning can be adapted for the consideration of varied ecological elements like wind speed and elevation increases or decreases to account for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will hit based upon the sight picture you are seeing with the scope as you align the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes and optics have around 11 parts which are found internally and externally on the scope body. These scope parts include the rifle scope’s body, lenses, elevation turrets, focus rings, and other parts. Learn about the eleven parts of scopes.
Rifle Glass Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Going for the perfect type of rifle optic is based around what type of shooting you plan on doing.
First Focal Plane Scope Facts
Focal plane scopes (FFP) include the reticle in front of the magnification lens. These kinds of scopes are helpful for:
- Quick acquisition, long distance types of shooting
- Shooting circumstances where calculations are very little
- Experienced shooters who recognize their target “hold over” and also “lead” ratios for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Second Focal Plane Glass Facts
Second focal plane optics (SFP) come with the reticle to the rear of the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement.
- Long distance forms of shooting where shooters have extra time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and distances
- Shooters who like a clearer optic picture without area taken up by the larger sized FFP reticle
Rifle Optic Zoom
The quantity of zoom a scope supplies is determined by the diameter, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Details
A single power rifle scope or optic will have a zoom number designator like 4×32. This suggests the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this type of optic can not change given that it is fixed.
Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. It will list the magnification degree in a configuration such as 2-10×32. These numbers suggest the magnification of the scope can be set in between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power adjustment is accomplished by employing the power ring component of the scope near the back of the scope by the eye bell piece.
Rifle Optic Power and Ranges
Here are some recommended scope powers and the ranges where they could be successfully used. Consider that high magnification optics and scopes will not be as effective as lower magnification level optics and scopes since excessive zoom can be a detractor. The exact same idea applies to extended ranges where the shooter needs to have increased power to see precisely where to best aim the rifle at the target.
Glass Lens Coating
All contemporary rifle optic lenses are layered. Lens finishing is a crucial element of a rifle’s setup when thinking about high end rifle optics and scope equipment.
HD Versus ED Lenses
Some scope brands likewise use “HD” or high-definition lens finishings which use different methods, polarizations, chemicals, and elements to draw out a wide range of colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Finish Versus Multi-Coating
Various optic lenses can likewise have various finishes applied to them. All lenses usually have at least some type of treatment or coating applied to them before being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single layered lens depends on the scope producer and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” covered. This implies the lens has had several treatments applied to them. If a lens gets multiple treatments, it can establish that a maker is taking numerous actions to combat various natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion finish, followed by a hydrophilic coating. This additionally doesn’t always imply the multi-coated lens is much better than a single layered lens. Being “better” hinges on the maker’s lens treatment techniques and the quality of components used in developing the rifle scope.
Rifle Glass Lens Anti-water Coating
Water on a lens does not help with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic coating.
Rifle Scope Installation Alternatives
Mounting approaches 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 types of mounts also usually are made in quick release versions which use toss levers which permit rifle operators to rapidly mount and dismount the glass.
Hex Key Rifle Scope Ring Mounting Solutions
Normal, clamp style 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 separate rings to support the optic, and are made from 7075 T6 billet aluminum which is created for long distance accuracy shooting. This type of scope install is excellent for rifles which require a resilient, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Optic Ring Mounts
These kinds of quick-release rifle scope mounts can be used to quickly attach and take off a scope from a rifle. If they all use a comparable design mount, multiple scopes can often be swapped on the range. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect solidly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted while keeping the original sighting settings. These types of mounts come in beneficial for shooting platforms which are transported a lot, to take off the scope from the rifle for protection, or for aiming systems which are chosen for use between a number of rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD
Sealing and Gas Purging for Rifle Glass Tubes
Moisture inside your rifle glass can spoil a day of shooting and your highly-priced optic by inducing fogging and generating residue within the scope tube. A lot of scopes protect against humidity from getting in the optical tube with a system of sealing O-rings which are waterproof. Usually, these water-resistant optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of wetness avoidance for common use rifles for hunting and sporting purposes, unless you anticipate taking your rifle boating and are worried about the optic still performing if it is submerged in water and you can still recover the gun.
Gas Purged Glass Tubes
Another element of avoiding the buildup of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the scope is less impacted by temperature level shifts and pressure differences from the outdoor environment which may potentially enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
