Info About Rifle Scopes
Rifle scopes allow you to specifically aim a rifle at different targets by lining up your eye with the target at range. They do this through magnifying the target by making use of a series of lenses inside the scope. The scope’s positioning can be dialed in to take into account numerous ecological considerations like wind and elevation to make up for bullet drop.
The scope’s purpose is to help shooters understand exactly where the bullet will hit based on the sight picture you are viewing through the scope as you line up the scope’s crosshair or reticle with the intended target. Many contemporary rifle scopes have around eleven parts which are arranged inside and externally on the optic. These parts include the rifle scope’s body, lenses, elevation dials or turrets, focus rings, and other elements. See all eleven parts of a rifle optical system.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The type of focal plane a scope has establishes where the reticle or crosshair is located in regard to the scopes zoom. It literally suggests the reticle is located behind or before the magnifying lens of the scope. Selecting the most ideal type of rifle glass depends upon what type of shooting you anticipate doing.
First Focal Plane Optic Facts
First focal plane glass (FFP) feature the reticle before the zoom lens. This induces the reticle to increase in size based upon the amount of magnification being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. As an example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the exact same tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, long distance types of shooting
- Shooting situations where computations are very little
- Experienced shooters who recognize their aim point “hold over” plus “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight space than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane scopes (SFP) come with the reticle behind the magnification lens. This induces the reticle to remain at the same scale in relation to the level of zoom being used. The result is that the reticle measurements shift based on the magnification applied to shoot over lengthier distances considering the markings present various increments which fluctuate with the zoom level. In the FFP example with the SFP glass, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick measurement. These varieties of scopes are convenient for:
- Long distance styles of shooting where shooters have additional time to make ballistic calculations
- Shooting where most of the shots happen within much shorter ranges and spaces
- Shooters who prefer a clearer optic sight picture with less area used up by the larger size FFP reticle
Details on Rifle Glass Magnification
The amount of zoom a scope offers is identified by the size, thickness, and curvatures of the lenses inside of the rifle scope. The magnification of the scope is the “power” of the scope.
Fixed Single Power Lens Rifle Glass Facts
A single power rifle optic comes with a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power while the objective lens is 32mm. The magnification of this kind of optic can not change given that it is a set power scope.
About Adjustable Power Lens Rifle Optics
Variable power rifle scopes can be modified between magnified levels. The power modification is performed using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range Correlation of Rifle Glass
Here are some advised scope power levels and the ranges where they can be efficiently used. Remember that high magnification optics will not be as efficient as lower powered optics and scopes because excessive magnification can be a detractor. The same idea applies to extended ranges where the shooter needs enough power to see where to properly aim the rifle.
Scope Lens Finish
All state-of-the-art rifle scope and optic lenses are layered. Lens coating is a vital aspect of a rifle system when looking into high end rifle optics and scope equipment.
HD Versus ED Rifle Glass Lens Coatings
Some scope makers also use “HD” or high-definition lens finishes which use different procedures, polarizations, chemicals, and elements to draw out different colors and viewable quality through the lens. Some scope manufacturers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Finish Versus Multi-Coating
Various optic lenses can likewise have various finishings applied to them. All lenses usually have at least some type of treatment or finish applied to them before they are used in a rifle scope or optic.
This lens treatment can offer protection to 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 coated lens depends on the scope maker and how much you paid for it.
Some scope producers likewise make it a point to specify if their optic lenses are coated or “multi” coated. This indicates the lens has had several treatments applied to the surfaces. If a lens gets numerous treatments, it can show that a producer is taking numerous steps to fight different natural factors like an anti-glare coating, a scratch resistant anti-abrasion finishing, followed by a hydrophilic covering. This also doesn’t always suggest the multi-coated lens is much better than a single layered lens. Being “much better” depends on the maker’s lens treatment solutions and the quality of glass used in developing the rifle optic.
Details on Anti-water Finishing
Water on an optical lens does not assist with keeping a clear sight picture through an optic in any way. Lots of top of the line and premium optic manufacturers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this type of treatment. It provides protection for the exterior of the Steiner optic lens so the H2O particles can not bind to it or produce surface tension. The result is that the water beads slide off of the scope to keep a clear, water free sight picture.
Rifle Glass Installation Options
Installing options for scopes are available in a few options. There are the basic scope rings which are separately installed to the scope and one-piece mounts which cradle the scope. These various kinds of mounts also usually are made in quick release variations which use throw levers which allow rifle shooters to quickly install and dismount the glass.
Hex Key Rifle Optic Ring Mounting Solutions
Standard, clamp-on style mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use two separate rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are created for far away precision shooting. This form of scope mount is good for rifle systems which are in need of a resilient, unfailing mount which will not change regardless of just how much the scope is moved or jarring the rifle takes. These are the style of mounts you want for a devoted scope system on a long distance scouting or tournament firearm that will pretty much never need to be changed or recalibrated. Blue 242 Loctite threadlocker can additionally be used to keep the hex screws from backing out after they are installed safely in place. An example of these rings are the 30mm type from Vortex Optics. The set normally costs around $200 USD
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to quickly connect and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be swapped out if they all use a compatible design mount. These types of mounts come in handy for long guns which are carried a lot, to swap out the optic from the rifle for protection, or for scopes which are used between numerous rifles or are situationally focused.
Scope Tube Sealing and Gas Purging
Wetness inside your rifle scope can destroy a day of shooting and your pricey optic by triggering fogging and making residue within the scope’s tube. A lot of optics protect against humidity from entering the optical tube with a series of sealing O-rings which are waterproof. Generally, these water resistant optics can be submerged within 20 or 30 feet of water before the water pressure can force moisture past the O-rings. This should be ample humidity prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle aboard a watercraft and are worried about the optic still performing if it is submerged in water and you can still find the gun.
Gas Purged Optic Tubes
Another element of avoiding the accumulation of wetness inside of 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 scope is less altered by temp changes and pressure variations from the outdoor environment which might possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to seek out.
