Rifle Optic Facts
Rifle scopes permit you to exactly aim a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through zoom by employing a set of lenses inside the scope. The scope’s positioning can be adjusted for the consideration of numerous environmental elements like wind speed and elevation increases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will hit based on the sight picture you are seeing through the scope as you align the scope’s crosshair or reticle with the target. A lot of modern rifle optics have about eleven parts which are found inside and externally on the scope. These optic pieces consist of the rifle scope’s body, lenses, windage dials or turrets, focus rings, and other components. Learn about the eleven parts of rifle scopes.
The Types of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Choosing the finest type of rifle scope depends on what type of shooting you plan to do.
First Focal Plane Optic Details
Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where calculations are minor
- Experienced shooters who understand their aim point “hold over” and “lead” ratios for their firearms
- Shooters who do not mind the reticle is bigger and takes up more visual eyesight area than a SFP reticle
About Second Focal Plane Scopes
Second focal plane scopes (SFP) include the reticle behind the zoom lens. In the FFP example with the SFP scope, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have increased time to make ballistic computations
- Shooting where most shots take place within much shorter distances and ranges
- Shooters who choose a clearer optic sight picture without room taken up by the larger size FFP reticle
Magnification for Rifle Optics
The quantity of zoom a scope supplies is figured out 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.
Single Power Lens Rifle Glass
A single power rifle optic uses a magnification number designator like 4×32. This indicates the magnification power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of optic can not adjust since it is a set power scope.
Variable Power Lens Glass
Variable power rifle scopes use variable power levels. The power modification is achieved by using the power ring part of the scope near the rear of the scope by the eye bell.
The Power and Range Correlation of Optics
Here are some recommended scope power settings and the ranges where they can be successfully used. Bear in mind that higher power optics and scopes will not be as practical as lower magnification level glass due to the fact that excessive zoom can be a negative thing in certain situations. The same goes for longer ranges where the shooter needs to have sufficient power to see exactly where to best aim the rifle at the target.
About Lens Covering
All top of the line rifle glass lenses are covered. Lens covering can be a vital element of a shooting system when purchasing high end rifle optics and scope systems.
ED Versus HD Rifle Optics
Some scope makers also use “HD” or high-definition lens finishes which use various processes, elements, polarizations, and chemicals to draw out separate colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” to signify the lens has extra-low dispersion glass.
Info on Single Finishing Versus Multi-Coating
Different optic lenses can also have different coatings used to them. All lenses typically have at least some type of treatment or coating used to them before being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less useful things experienced in the shooting environment while sighting in with the scope. The quality of a single coated lens depends on the scope producer and how much you paid for it.
Some scope producers also make it a point to specify if their optic lenses are layered or “multi” covered. This implies the lens has had multiple treatments applied to them. If a lens receives several treatments, it can establish that a producer is taking several actions to combat different environmental factors like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finish. This also does not necessarily imply the multi-coated lens is much better than a single covered lens. Being “much better” depends on the manufacturer’s lens treatment technology and the quality of products used in building the rifle glass.
Hydrophobic Scope Lens Finish
Water on a lens does not help 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 finishing which is water repellent.
Options for Installing Glass on Firearms
Mounting solutions for scopes are available in a few 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 typically come in quick release variations which use toss levers which permit rifle shooters to rapidly mount and dismount the optics.
Hex Key Glass Rings
Basic, clamp-on type mounting scope rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These kinds of scope mounts use two individual rings to support the optic, and are usually constructed from 7075 T6 billet aluminum which are manufactured for far away accuracy shooting. This type of scope mount is excellent for rifle systems which need a durable, hard use mount which will not move despite how much the scope is moved or jarring the rifle takes. These are the type of mounts you want for a devoted scope system on a reach out and touch someone scouting or sniper competition long gun which will almost never need to be altered or recalibrated. Blue 242 Loctite threadlocker can also be used on the mount screws to stop the hex screws from backing out after they are installed safely in position. An example of these mounting rings are the 30mm style from Vortex Optics. The set generally costs around $200 USD
Rifle Glass Mounts with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle. A wide range of scopes can also be swapped out if they all use a complementary style mount. The quick detach mount style is CNC machined from anodized 6061 T6 aluminum and the mounting levers connect securely to a flat top style Picatinny rail. This lets the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while preserving accuracy. These types of mounts are useful and convenient for shooting platforms which are carried a lot, to take off the scope glass from the rifle for protection, or for scopes which are chosen for use between numerous rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It generally costs around $250 USD
Sealing and Gas Purging for Rifle Optic Tubes
Moisture inside your rifle optic can mess up a day of shooting and your pricey optic by causing fogging and making residue within the scope’s tube. Most optics protect against wetness from entering the scope tube with a series of sealing O-rings which are waterproof. Usually, these water-resistant optics can be submerged under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be more than enough moisture prevention for standard use rifles, unless you plan on taking your rifle sailing and are concerned about the optic still performing if it is submerged in water and you can still rescue the gun.
Details on Rifle Scope Tube Gas Purging
Another element of preventing the buildup of moisture within the rifle scope’s tube is filling the tube with a gas like nitrogen. Considering that this area is already taken up by the gas, the optic is less influenced by condition alterations and pressure differences from the outdoor environment which might potentially allow 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.
