Rifle scopes allow you to exactly aim a rifle at different targets by aligning your eye with the target over a distance. They accomplish this through zoom by making use of a series of lenses within the scope. The scope’s positioning can be adapted for consideration of many environmental things like wind and elevation increases or decreases to account for bullet drop.
The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are seeing with the optic as you align the scope’s crosshair or reticle with the intended target. Many modern rifle scopes have around eleven parts which are arranged inside and outside of the scope body. These optic pieces consist of the rifle scope’s body, lenses, windage and elevation dials or turrets, objective focus rings, and other parts. See all eleven parts of a scope.
Rifle Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane a scope has determines where the reticle or crosshair lies relative to the scopes magnifying adjustments. It literally implies the reticle is behind or before the magnification lens of the optic. Choosing the most beneficial style of rifle glass depends on what style of shooting or hunting you intend on undertaking.
First Focal Plane Glass
First focal plane optics (FFP) include the reticle before the magnification lens. This triggers the reticle to increase in size based upon the level of magnification being used. The benefit is that the reticle measurements are the same at the amplified distance as they are at the non amplified distance. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These types of scopes are practical for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where computations are small
- Experienced shooters who know their aim point “hold over” and also “lead” ratios for their firearms
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Info About Second Focal Plane Glass
Second focal plane scopes (SFP) include the reticle to the rear of the zoom lens. This triggers the reticle to remain at the same scale in relation to the volume of magnification being used. The end result is that the reticle dimensions shift based on the magnification chosen to shoot over lengthier ranges given that the markings present different increments which can vary with the magnification. In the FFP illustration with the SFP glass, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick reticle measurement. These particular types of optics are convenient for:
- Far away styles of shooting where shooters have increased time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and distances
- Shooters who prefer a clearer optic sight picture with less area taken up by the larger sized FFP reticle
The extent of scope zoom you need on your glass depends upon the kind of shooting you want to do. Virtually every kind of rifle optic delivers some level of zoom. The quantity of magnification a scope supplies is determined by the dimension, thickness, and curves of the lens glass within the rifle optic. The magnification of the optic is the “power” of the opic. This indicates what the shooter is observing through the scope is amplified times the power aspect of what can usually be seen by human eyes.
Single Power Lens Rifle Glass Facts
A single power rifle optic will have 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 zoom of this kind of optic can not fluctuate given that it is fixed.
Info About Adjustable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will list the magnification level in a configuration such as 2-10×32. These numbers indicate the magnification of the scope can be adjusted between 2x and 10x power. This always incorporates the power levels in-between 2 and 10. The power manipulation is achieved by applying the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range of Rifle Scopes
Here are some advised scope power levels and the distances where they may be effectively used. Bear in mind that higher magnification scopes will not be as practical as lower powered scopes because excessive zoom can be a negative thing in certain situations. The same goes for longer ranges where the shooter needs to have increased power to see exactly where to best aim the rifle at the target.
Details on Glass Lens Finishing
All modern rifle scope lenses are layered. Lens finishing is a vital aspect of a shooting platform when looking at high end rifle optics and scope setups.
HD Versus ED Lens Coatings
Some scope producers also use “HD” or high-definition lens coatings which use various procedures, polarizations, chemicals, and components to draw out different colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Glass Lens Finish Versus Multi-Coating
Various optic lenses can likewise have different finishes applied to them. All lenses normally have at least some type of treatment or covering applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while lowering 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 maker and how much you paid for it.
Some scope manufacturers likewise make it a point to specify if their optic lenses are coated or “multi” covered. This means the lens has multiple treatments applied to the surfaces of the glass. If a lens receives several treatments, it can establish that a producer is taking numerous steps to fight various environmental factors like an anti-glare covering, a scratch resistant anti-abrasion finishing, followed by a hydrophilic finishing. This also doesn’t always mean the multi-coated lens is much better than a single layered lens. Being “much better” hinges on the maker’s lens treatment technology and the quality of materials used in developing the rifle optic.
Hydrophobic Lens Finishing
Water on a lens doesn’t assist with preserving a clear sight picture through a scope at all. Numerous top of the line and military grade optic companies will coat their lenses with a hydrophilic or hydrophobic anti-water coating.
Rifle Scope Mounting Choices
Installing options for scopes are available in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also generally are made in quick release versions which use throw levers which allow rifle operators to rapidly install and dismount the optics.
Optic Mounts with Hex Key Rings
Standard, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope installation rails on rifles. These types of scope mounts use two separate rings to support the optic, and are often made from 7075 T6 billet aluminum which are designed for long range accuracy shooting. This type of scope install is perfect for rifles which need a durable, rock solid mount which will not move no matter how much the scope is moved or abused.
Rifle Optic Mounts with Quick-Release Cantilever Rings
These types of quick-release rifle scope mounts can be used to rapidly take off a scope and connect 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 transferred a lot, to swap out the optic from the rifle for protection, or for optics which are used in between numerous rifles.
Scope Tube Sealing and Gas Purging
Wetness inside your rifle optic can ruin a day of shooting and your expensive optic by triggering fogging and developing residue inside of the scope tube. Many scopes avoid wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Optic Gas Purging
Another component of avoiding the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Given that this area is already taken up by the gas, the scope is less impacted by climate shifts and pressure variations from the external environment which could potentially permit water vapor to permeate 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.
