Information About Optics
Rifle scopes enable you to specifically align a rifle at various targets by lining up your eye with the target over a range. They accomplish this through magnifying the target by making use of a set of lenses within the scope. The scope’s alignment can be adapted to account for separate ecological things like wind and elevation increases to account for bullet drop.
The scope’s purpose is to understand precisely where the bullet will land based upon the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. The majority of contemporary rifle scopes have about 11 parts which are located inside and externally on the optic. These optic pieces consist of the rifle scope’s body, lenses, windage turrets or dials, focus rings, and other components. Learn about the eleven parts of rifle scopes.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the finest type of rifle scope is based around what type of shooting you plan to do.
Info on First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This induces the reticle to increase in size based on the extent of magnification being used. The benefit is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These types of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting scenarios where calculations are small
- Experienced shooters who have an idea for their target “hold over” plus “lead” correlations for their rifles
- Shooters who don’t mind the reticle is bigger and occupies more visual eyesight space than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane glass (SFP) come with the reticle to the rear of the zoom lens. This causes the reticle to stay at the very same overall size in relation to the volume of magnification being used. The effect is that the reticle measurements shift based upon the zoom employed to shoot over greater ranges given that the markings present various increments which differ with the zoom level. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick reticle measurement. These sorts of glass work for:
- Long distance types of shooting where shooters have additional time to make ballistic estimations
- Shooting where most shots occur within shorter ranges and distances
- Shooters who choose a clearer optic picture with less space used up by the enlarged FFP reticle
Scope Zoom
The extent of scope zoom you need depends on the type of shooting you choose to do. Just about every type of rifle scope provides some level of zoom. The quantity of zoom a scope offers is determined by the size, density, and curves of the lenses within the rifle scope. The magnification of the optic is the “power” of the glass. This denotes what the shooter is checking out through the scope is magnified times the power element of what can typically be seen by human eyes.
Single Power Lens Optics
A single power rifle scope uses a zoom number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of optic can not adjust considering that it is a fixed power scope.
Variable Power Lens Rifle Glass Info
Variable power rifle scopes use enhanced power. The power modification is handled 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 Scopes
Here are some advised scope power levels and the ranges where they can be successfully used. Highly magnified scopes will not be as useful as lower powered rifle scope glass because too much zoom can be a bad thing. The same goes for extended distances where the shooter needs sufficient power to see precisely where to best aim the rifle.
Rifle Glass Lens Coating
All contemporary rifle scope lenses are layered. There are various types and qualities of glass lens coatings. When thinking about luxury rifle targeting devices, Lens coating can be an important element of defining the capability of the rifle. The glass lenses are one of the most significant parts of the scope since they are what your eye looks through while sighting a rifle in on the target. The coating on the lenses offers protection to the lens exterior and assists with anti glare from refracted sunlight and color recognition.
About Rifle Scope Lens Coatings – HD Versus ED
Some scope brands likewise use “HD” or high-definition lens finishes which use various processes, chemicals, polarizations, and components to draw out different colors and viewable quality through the lens. Some scope producers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Rifle Glass Lens Finishing Versus Multi-Coating
Various scope lenses can even have various coverings applied to them. All lenses usually have at least some kind of treatment or covering 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 finely tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
Single layered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less useful 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 just how much you spent paying for it. Both the make and cost are signs of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has had several treatments applied to the surfaces of the glass. If a lens gets multiple treatments, it can indicate that a company is taking numerous actions to fight different natural aspects like an anti-glare finishing, a scratch resistant anti-abrasion finishing, followed by a hydrophilic coating. This also doesn’t always mean the multi-coated lens is better than a single layered lens. Being “much better” depends upon the manufacturer’s lens treatment techniques and the quality of materials used in creating the rifle glass.
Scope Lens Anti-water Finishing
Water on a lens doesn’t improve retaining a clear sight picture through a scope whatsoever. Many top of the line and premium scope producers 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 exterior of the Steiner glass lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads move off of the scope to maintain a clear, water free sight picture.
Choices for Mounting Optics on Long Guns
Mounting approaches for scopes are available in a couple of options. There are the standard scope rings which are individually mounted to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also generally come in quick release variations which use manual levers which enable rifle shooters to quickly mount and remove the scopes.
Hex Key Glass Ring Mounts
Basic, clamp design mounting scope rings use hex head screws to position to the flattop style Picatinny scope mount rails on rifles. These kinds of scope mounts use double detached rings to support the optic, and are usually constructed from 7075 T6 billet aluminum or similar materials which are created for long distance precision shooting. This kind of scope mount is good for rifles which require a durable, hard use mount which will not move no matter how much the scope is moved about or abuse the rifle takes. These are the type of mounts you should have for a faithful optics system on a reach out and touch someone hunting or tournament rifle which will seldom need to be altered or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the scope mount’s screws to protect against the hex screws from wiggling out after they are mounted securely in place. An example of these mounting rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD
Scope Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to quickly take off a scope and attach it to a different rifle. Multiple scopes can even be swapped out if they all use a similar design mount. These types of mounts come in handy for rifles which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between several rifles.
Info on Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and developing residue inside of the scope tube. Most scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Scope Gas Purging
Another part of avoiding the accumulation of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the scope is less affected by climate alterations and pressure variations from the outside environment which might potentially permit 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.
