Rifle Scope Info
Rifle scopes permit you to precisely align 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 set of lenses within the scope. The scope’s positioning can be adjusted to take into account many ecological things like wind speed and elevation to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based on the sight picture you are viewing through the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle scopes and optics have around 11 parts which are located inside and externally on the optic. These parts consist of the rifle scope’s body, lenses, elevation dials or turrets, objective focus rings, and other components. See all eleven parts of scopes.
Rifle Scope Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding on the optimal type of rifle scope is based around what type of shooting you plan to do.
First Focal Plane Scopes
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the amount of magnification being used. The result is that the reticle measurements are the same at the amplified distance as they are at the non magnified range. For instance, one tick on a mil-dot reticle at 100 yards without having “zoom” is still the exact same tick at one hundred yards with 5x “zoom”. These types of scopes are valuable for:
- Quick acquisition, long distance kinds of shooting
- Shooting circumstances where computations are marginal
- Experienced shooters who understand their target “hold over” and “lead” ratios for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Second Focal Plane Glass
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” 100 yard tick would be 1/5th of the non “zoom” tick measurement.
- Far away kinds of shooting where shooters have additional time to make ballistic calculations
- Shooting where most shots happen within much shorter ranges and spaces
- Shooters who want a clearer optic picture with less room used up by the larger size FFP reticle
About Glass Magnification
The amount of scope magnification you need is based on the sort of shooting you wish to do. Nearly every kind of rifle glass supplies some level of magnification. The amount of zoom a scope supplies is determined by the size, density, and curves of the lens glass inside of the rifle optic. The zoom of the optic is the “power” of the opic. This indicates what the shooter is looking at through the scope is magnified times the power factor of what can generally be seen by human eyes.
Info on Fixed Power Lens Rifle Scopes
A single power rifle optic uses a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of scope can not change because it is a fixed power scope.
Variable Power Lens Rifle Scope Facts
Variable power rifle scopes have adjustable power. These types of scopes will note the magnification degree in a format such as 2-10×32. These numbers suggest 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 manipulation is accomplished by working with the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope power settings and the distances where they could be successfully used. Bear in mind that higher power optics and scopes will not be as effective as lower magnification level scope and optics due to the fact that too much magnification can be a bad thing. The exact same concept goes for longer distances where the shooter needs sufficient power to see where to properly aim the rifle.
Lens Covering for Scopes
All current rifle scope lenses are layered. Lens finish is an essential aspect of a rifle when purchasing high end rifle optics and scope setups.
Info on Lens Coatings – HD Versus ED
Some rifle glass suppliers additionally use “HD” or high-def glass finishings that make the most of various procedures, polarizations, elements, and chemicals to enhance numerous colors and viewable target definition through the lens. This high-def finish is frequently used with higher density lens glass which decreases light’s capability to refract through the lens glass. Some scope producers use “HD” to describe “ED” meaning extra-low dispersion glass. ED deals with how colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration is often visible over items with hard shapes as light hits the item from specific angles.
Glass Lens Single Finish Versus Multi-Coating
Different optic lenses can also have different coverings applied to them. All lenses usually have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic.
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 manufacturer and how much you paid for it.
Some scope producers similarly make it a point to define if their optic lenses are coated or “multi” coated. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of materials used in building the rifle scope.
Anti-water Lens Finish
Water on a scope lens does not assist with keeping a clear sight picture through an optic at all. Lots of top of the line or premium optic makers will coat their lenses with a hydrophobic or hydrophilic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It treats the surface area of the Steiner glass lens so the water particles can not bind to it or create surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Options for Mounting Glass on Firearms
Installing solutions for scopes are available in a few choices. There are the standard scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These different types of mounts also normally are made in quick release versions which use toss levers which permit rifle operators to quickly install and remove the scopes.
Hex Key Optic Ring Mounting Solutions
Basic, clamp-on design mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mount rails on the tops of rifles. These varieties of scope mounts use double separate rings to support the optic, and are made from 7075 T6 billet aluminum which are developed for far away precision shooting. This form of scope mount is very good for rifles which require a durable, unfailing mount which will not change despite how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a dedicated optics system on a far away hunting or hard target interdiction long gun that will almost never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used to prevent the hex screws from backing out after they are mounted securely in place. An example of these mounting rings are the 30mm type made by the Vortex Optics company. The set usually costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to quickly connect and take off a scope from a rifle. Multiple scopes can also be swapped out if they all use a complementary style mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten securely to a flat top design Picatinny rail. This permits the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while retaining accuracy. These kinds of mounts are useful and handy for shooting platforms which are hauled around a lot, to remove the scope from the rifle for protection, or for scopes which are adopted in between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Info Around Glass Tube Sealing and Gas Purging
Wetness inside your rifle scope can mess up a day of shooting and your pricey optic by causing fogging and creating residue inside of the scope tube. The majority of scopes avoid moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another component of avoiding the accumulation of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Because this space is already taken up by the gas, the glass is less impacted by temperature level changes and pressure distinctions from the outside 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 good rifle scope to look for.
