Rifle Scope Info
Rifle scopes permit you to specifically aim a rifle at different targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by employing a series of lenses inside the scope. The scope’s alignment can be adjusted to take into account various ecological things like wind speed and elevation increases to make up for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based upon the sight picture you are seeing through the optic as you align the scope’s crosshair or reticle with the target. Many modern rifle scopes and optics have about eleven parts which are found inside and externally on the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other elements. See all eleven parts of scopes.
About Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Finding the best type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Scope Facts
Focal plane scopes (FFP) feature the reticle in front of the zoom lens. These kinds of scopes are beneficial for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are minor
- Experienced shooters who understand their target “hold over” and also “lead” relationships for their firearm
- Shooters who don’t mind the reticle is bigger and requires more visual eyesight area than a SFP reticle
Info on Second Focal Plane Optics
Second focal plane scopes (SFP) feature the reticle to the rear of the magnification 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.
- Far away forms of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots take place within much shorter proximities and ranges
- Shooters who select a clearer optic picture with less space used up by the enlarged FFP reticle
Ins and Outs of Rifle Optic Magnification
The level of scope magnification you need on your optic depends upon the kind of shooting you want to do. Practically every style of rifle scope offers some degree of magnification. The level of magnification a scope provides is identified by the size, thickness, and curvatures of the lenses within the rifle optic. The magnification level of the optic is the “power” of the opic. This denotes what the shooter is checking out through the scope is amplified times the power element of what can usually be seen by human eyes.
Fixed Single Power Lens Rifle Optic Facts
A single power rifle optic and scope comes with a magnification number designator like 4×32. This indicates the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not fluctuate because it is a fixed power optic.
Variable Power Lens Optics
Variable power rifle scopes have adjustable power. It will list the zoom amount in a format like 2-10×32. These numbers imply the magnification of the scope could be set between 2x and 10x power. This also includes the power levels in-between 2 and 10. The power shift is achieved using the power ring part of the scope near the rear of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope powers and the ranges where they could be efficiently used. Always remember that high power optics and scopes will not be as effective as lower magnification level scopes since excessive zoom can be a detractor. The same idea applies to extended ranges where the shooter needs enough power to see exactly where to properly aim the rifle.
Glass Lens Covering
All modern rifle optic and scope lenses are layered. There are different types and qualities of glass coatings. Lens covering can be a crucial aspect of a rifle’s setup when looking at high end rifle optics and scope systems. The lenses are one of the most key parts of the scope due to the fact that they are what your eye sees through while sighting a rifle in on the target. The covering on the lenses protects the lens exterior and helps with anti glare capabilities from excess light and color profiles.
About Rifle Optic Lens Coatings – HD Versus ED
Some scope makers also use “HD” or high-definition lens finishes which use various procedures, components, polarizations, and chemicals to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Single Scope Lens Finishing Versus Multi-Coating
Different optic lenses can even have various coatings applied to them. All lenses usually have at least some kind of treatment or coating applied to them prior to being used in a rifle scope or optic. This is because the lens isn’t simply a raw piece of glass. It is part of the carefully tuned optic. It requires a coating to be applied to it so that it will be efficiently functional in lots of types of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while minimizing glare and other less beneficial 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 makers also make it a point to define if their optic lenses are covered or “multi” coated. This indicates the lens has had several treatments applied to them. If a lens gets multiple treatments, it can show that a manufacturer is taking several steps to fight different environmental aspects like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also does not necessarily suggest the multi-coated lens is much better than a single coated lens. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle glass.
Hydrophobic Lens Coatings
Water on an optic’s lens doesn’t help with maintaining a clear sight picture through an optic at all. Lots of top of the line or high-end optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It deals with the surface of the Steiner scope lens so the H2O molecules can not bind to it or develop surface tension. The result is that the water beads roll off of the scope to maintain a clear, water free sight picture.
Glass Installing Options
Installing options for scopes come in a couple of choices. There are the standard scope rings which are separately mounted to the scope and one-piece mounts which cradle the scope. These different types of mounts also usually come in quick release versions which use throw levers which permit rifle shooters to quickly mount and dismount the scope.
Hex Key Rifle Optic Ring Mounting Solutions
Standard, clamp type mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on the tops of rifles. These varieties of scope mounts use a pair of individual rings to support the optic, and are made from 7075 T6 billet aluminum which are manufactured for long distance accuracy shooting. This kind of scope mount is exceptional for rifles which need to have a durable, hard use mount which will not change despite just how much the scope is moved about or abuse the rifle takes. These are the design of mounts you should have for a dedicated optics setup on a reach out and touch someone scouting or interdiction long gun that will almost never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used to stop the hex screw threads from backing out after they are installed safely in place. An example of these mounting rings are the 30mm style from Vortex Optics. The set usually costs around $200 USD
Quick-Release Cantilever Scope Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly attach and detach a scope from a rifle before reattaching it to a different rifle. Multiple scopes can even be switched out if they all use a compatible style mount. These types of mounts are convenient for long guns which are transported a lot, to remove the optic from the rifle for protection, or for optics which are used in between several rifles.
Sealing and Gas Purging for Scope Tubes
Wetness inside your rifle optic can ruin a day of shooting and your highly-priced optic by inducing fogging and generating residue inside of the scope’s tube. Many optics protect against humidity from getting in the optical tube with a system of sealing O-rings which are water resistant. Generally, these water resistant scopes can be submerged within 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture avoidance for common use rifles for hunting and sporting purposes, unless you plan on taking your rifle on a boat and are worried about the scope still functioning if it goes over the side and you can still find the firearm.
Gas Purged Rifle Optic Tubes
Another part of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is currently occupied by the gas, the glass is less influenced by temperature level shifts and pressure distinctions from the outside environment which might potentially allow water vapor to leak in around the seals to fill the void which would otherwise be there. These are good qualities of a good rifle scope to seek out.
