What You Need to Know About Scopes
Rifle scopes permit you to precisely aim a rifle at various targets by lining up your eye with the target over a distance. They do this through magnification by using a set of lenses within the scope. The scope’s positioning can be adjusted for the consideration of numerous natural aspects like wind and elevation to make up for bullet drop.
The scope’s function is to help shooters understand exactly where the bullet will land based upon the sight picture you are seeing via the scope as you line up the scope’s crosshair or reticle with the intended point of impact. A lot of modern-day rifle scopes have about eleven parts which are arranged inside and on the exterior of the optic. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, focus rings, and other parts. See all eleven parts of a rifle optical system.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the perfect type of rifle optic is based around what type of shooting you plan to do.
First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the magnified range as they are at the non magnified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at 100 yards by using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where estimations are marginal
- Experienced shooters who understand their target “hold over” as well as “lead” ratios for their long guns
- Shooters who don’t mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle
Second Focal Plane Glass Details
Second focal plane optics (SFP) feature 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 measurement.
- Long distance styles of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and proximities
- Shooters who want a clearer optic sight picture with less room taken up by the larger size FFP reticle
Details on Scope Magnification
The quantity of magnification a scope supplies is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Single Power Lens Optic Details
A single power rifle scope and optic uses a magnification number designator like 4×32. This means the magnification power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of optic can not change since it is fixed.
Adjustable Power Lens Glass
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom level in a format like 2-10×32. These numbers imply the magnification of the scope could be adjusted between 2x and 10x power. This also includes the powers in-between 2 and 10. The power modification is achieved by employing the power ring component of the scope near the rear of the scope by the eye bell piece.
Scope Power Level and Ranges
Here are some recommended scope power settings and the ranges where they could be successfully used. High power scopes will not be as effective as lower magnification glass because too much magnification can be a bad thing. The same concept relates to extended ranges where the shooter needs adequate power to see where to best aim the rifle at the target.
Info on Optic Lens Finishes
All modern rifle scope and optic lenses are layered. There are different types and qualities of lens finishings. Lens finishing is an important aspect of a rifle’s setup when considering luxury rifle optics and targeting units. The lenses are one of the most vital components of the scope considering they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses protects the lens surface area and even assists with anti glare from excess sunlight and color recognition.
HD Versus ED Lens Coatings
Some scope brands likewise use “HD” or high-definition lens finishings which use various techniques, chemicals, elements, and polarizations to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Finish Versus Multi-Coating for Rifle Glass
Various optic lenses can also have different finishes applied to them. All lenses generally have at least some kind of treatment or coating applied to them before they are used in a rifle scope or optic assembly. This is due to the fact that the lens isn’t simply a raw piece of glass. It is part of the finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently functional in lots of kinds of environments, degrees of sunshine (full light VS shaded), and other shooting conditions.
This lens treatment can protect the lens from scratches while lowering 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 maker 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 suggests the lens has had multiple treatments applied to them. If a lens receives several treatments, it can indicate that a producer is taking multiple actions to fight various environmental elements like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also doesn’t always suggest the multi-coated lens is better than a single coated lens. Being “better” hinges on the manufacturer’s lens treatment solutions and the quality of products used in creating the rifle optic.
Hydrophobic Lens Coverings
Water on a lens doesn’t help with keeping a clear sight picture through a scope at all. Numerous top of the line and military grade scope makers will coat their lenses with a hydrophilic or hydrophobic finishing.
Choices for Installing Rifle Optics on Long Guns
Installing approaches for scopes are available in a couple of options. 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 normally come in quick release versions which use throw levers which allow rifle operators to rapidly mount and dismount the scope.
Hex Key Glass Ring Mounts
Basic, clamp style mounting scope rings use hex head screws to install to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use double individual rings to support the scope, and are normally made from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This type of scope mount is good for rifles which are in need of a long lasting, unfailing mount which will not change regardless of how much the scope is moved about or abuse the rifle takes. These are the style of mounts you really want to have for a specialized optics system on a far away scouting or competition firearm that will hardly ever need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount screws to stop the hex screws from backing out after they are installed safely in position. An example of these rings are the 30mm type made by the Vortex Optics company. The set typically costs around $200 USD
Quick-Release Cantilever Scope Ring Mounts
These types of quick-release rifle scope mounts can be used to quickly attach and remove a scope from a rifle. Multiple scopes can also be swapped out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted while preserving the original sighting settings. These types of mounts come in handy for rifles which are transferred a lot, to remove the glass from the rifle for protection, or for sight systems which are employed in between a number of rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics brand. It typically costs around $250 USD
Scope Tube Sealing and Gas Purging
Moisture inside your rifle optic can mess up a day of shooting and your expensive optic by inducing fogging and producing residue within the scope’s tube. The majority of scopes protect against moisture from going into the scope tube with a series of sealing O-rings which are waterproof. Normally, these water resistant optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be more than enough wetness prevention for basic use rifles, unless you anticipate taking your rifle boating and are worried about the scope still functioning if it is submerged in water and you can still salvage the rifle.
Rifle Optic Gas Purging
Another component of preventing the buildup of wetness inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Because this area is currently occupied by the gas, the glass is less influenced by temp shifts and pressure variations from the outdoor environment which could possibly enable water vapor to seep in around the seals to fill the void which would otherwise be there. These are good qualities of a decent rifle scope to seek out.
