What You Need to Know About Scopes
Rifle scopes enable you to exactly align a rifle at different targets by aligning your eye with the target over a distance. They do this through zoom by using a series of lenses inside the scope. The scope’s positioning can be adjusted for consideration of different ecological aspects like wind and elevation increases to account for bullet drop.
The scope’s function is to help the shooter understand exactly where the bullet will land based on the sight picture you are viewing via the scope as you line up the scope’s crosshair or reticle with the intended target. Many modern rifle scopes and optics have around eleven parts which are found internally and on the exterior of the optic. These scope parts consist of the rifle scope’s body, lenses, elevation turrets or dials, objective focus rings, and other parts. Learn about the eleven parts of rifle optics.
Rifle Optic Styles
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The kind of focal plane an optic has decides where the reticle or crosshair lies relative to the scopes zoom. It literally indicates the reticle is behind or in front of the magnification lens of the scope. Picking out the most ideal form of rifle optic is based on what variety of hunting or shooting you intend on undertaking.
Info on First Focal Plane Optics
First focal plane glass (FFP) feature the reticle in front of the zoom lens. This induces the reticle to increase in size based on the level 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 distance. One tick on a mil-dot reticle at one hundred yards without “zoom” is still the identical tick at one hundred yards by using 5x “zoom”. These kinds of scopes are beneficial for:
- Quick acquisition, far away types of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who recognize their aim point “hold over” plus “lead” equations for their firearms
- Shooters who don’t mind the reticle is bigger and takes up more visual sight room than a SFP reticle
About Second Focal Plane Glass
Second focal plane optics (SFP) include the reticle behind the magnification lens. This induces the reticle to remain at the very same scale in relation to the quantity of zoom being used. The result is that the reticle dimensions evolve based upon the magnification employed to shoot over lengthier ranges because the reticle markings present distinct increments which fluctuate with the zoom level. In the FFP illustration with the SFP glass, the 5x “zoom” 100 yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These types of optics work for:
- Far away styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots happen within much shorter ranges and distances
- Shooters who desire a clearer optic picture without area used up by the larger size FFP reticle
Zoom for Rifle Optics
The quantity of zoom a scope supplies is identified by the diameter, density, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Info on Single Power Lens Scopes
A single power rifle optic and scope comes with a zoom number designator like 4×32. This suggests the magnification power of the scope is 4x power while the objective lens is 32mm. The magnification of this type of optic can not adjust since it is a set power scope.
Variable Power Lens Rifle Optic Info
Variable power rifle scopes have adjustable power. It will list the zoom degree in a configuration such as 2-10×32. These numbers suggest the zoom of the scope could be changed between 2x and 10x power. This always utilizes the powers in-between 2 and 10. The power modification is achieved by employing the power ring part of the scope near the rear of the scope by the eye bell piece.
Rifle Optic Power Level and Range Correlation
Here are some advised scope power levels and the distances where they could be efficiently used. Highly magnified rifle scope glass will not be as effective as lower magnification glass due to the fact that too much zoom can be a negative aspect depending on your shooting distance. The same concept goes for extended ranges where the shooter needs enough power to see exactly where to best aim the rifle at the target.
Scope Lens Coating
All modern-day rifle optic lenses are layered. There are various types and qualities of glass finishings. Lens covering can be an important aspect of a rifle when thinking of high-end rifle optics and targeting units. The glass lenses are among the most key pieces of the optic as they are what your eye sees through while sighting a rifle in on the point of impact. The finishing on the lenses protects the lens surface and also helps with anti glare from excess sunrays and color discernibility.
HD Versus ED Glass Lens Coatings
Some scope brands also use “HD” or high-definition lens finishes which use various processes, polarizations, elements, and chemicals to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Scopes
Various optic lenses can also have various finishings applied to them. All lenses generally have at least some type of treatment or finishing used to them prior to being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is normally a protective and improving multi-purpose treatment. This lens treatment can shield the lens from scratches while minimizing glare and other less advantageous things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends upon the scope producer and just how much you spent on it. Both are indications of the lens quality.
Some scope makers also make it a point to define if their optic lenses are covered or “multi” covered. This means the lens has had numerous treatments applied to the surfaces. If a lens gets several treatments, it can establish that a producer is taking numerous actions to combat different natural elements like an anti-glare coating, a scratch resistant anti-abrasion coating, followed by a hydrophilic finish. This additionally does not necessarily imply the multi-coated lens is better than a single layered lens. Being “better” depends on the producer’s lens treatment solutions and the quality of glass used in constructing the rifle scope.
Anti-water Scope Lens Finish
Water on a scope’s lens does not improve maintaining a clear sight picture through an optic in any way. Lots of top of the line and premium scope makers will coat their lenses with a hydrophobic or hydrophilic coating. The Steiner Optics Nano-Protection is a fine example of this sort of treatment. It treats the surface area of the Steiner scope lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Rifle Glass Installing Choices
Mounting options for scopes come in a couple of choices. There are the basic scope rings which are separately mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally can be found in quick release versions which use throw levers which allow rifle operators to rapidly mount and remove the optics.
Hex Key Scope Ring Mounting Solutions
Basic, clamp design mounting scope rings use hex head screws to install to the flattop design Picatinny scope mounting rails on the tops of rifles. These styles of scope mounts use two individual rings to support the optic, and are normally made from 7075 T6 billet aluminum or similar materials which are developed for long distance precision shooting. This kind of scope mount is very good for rifle systems which are in need of a durable, unfailing mount which will not move regardless of how much the scope is moved or abuse the rifle takes. These are the type of mounts you really want to have for a dedicated scope setup on a far away scouting or hard target interdiction rifle which will pretty much never need to be changed or adjusted. Blue 242 Loctite threadlocker can also be used on the screws to stop the hex screw threads from wiggling out after they are installed tightly in place. An example of these mounting rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly remove 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 rifle platforms which are carried a lot, to remove the optic from the rifle for protection, or for scopes which are used in between numerous rifles.
Info Around Optic Tube Sealing and Gas Purging
Moisture inside your rifle optic can ruin a day of shooting and your costly optic by triggering fogging and creating residue inside of the scope tube. The majority of scopes prevent moisture from going into the scope tube with a system of sealing O-rings which are water resistant.
Rifle Glass Gas Purging
Another element of preventing the accumulation of moisture within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is currently taken up by the gas, the optic is less impacted by temperature alterations and pressure differences from the outdoor environment which could potentially allow water vapor to permeate in around the seals to fill the void which would otherwise exist. These are good qualities of a good rifle scope to seek out.
