Rifle Scope Product Details

Nightforce BEAST 5-25×56 F1 ZS i4F Ill Brke PTL TreMor3 C576
This Nightforce Beast 5-25×56 riflescope with Tremor 3 reticle features Zerostop, I4F, .1 Mil-Radian, and a parallax adjustment of 45 meters to infinity. Why is Nightforce’s most advanced riflescope called the BEAST It’s not about size, weight, or appearance. The Nightforce BEAST is called that because nothing like it has ever created before now. To solve problems with older models Nightforce used new technologies to create the BEAST. The goal was to include features that would have been pipe dreams to others. Nightforce’s BEAST is the end product of that goal. Nightforce is pleased to offer the BEAST to hunters worldwide. Creating the BEAST was a challenging, demanding, and overwhelming task. The only fitting name for this product is BEAST since it seems like a monster. BEAST stands for “Best Example of Advanced Scope Technology.” Because that’s what it is.

Info Rifle Scopes

Rifle scopes enable you to specifically align a rifle at different targets by lining up your eye with the target at range. They do this through zoom by using a set of lenses within the scope. The scope’s positioning can be adapted to take into account separate natural factors like wind and elevation increases to make up for bullet drop.

The scope’s function is to understand exactly where the bullet will hit based on the sight picture you are viewing with the scope as you align the scope’s crosshair or reticle with the target. Most modern-day rifle scopes and optics have around eleven parts which are located inside and externally on the scope body. These parts include the rifle scope’s body, lenses, windage turrets, focus rings, and other parts. See all eleven parts of a rifle scope.

The Styles of Rifle Scopes

Rifle scopes can be either “first focal plane” or “second focal plane” type of optics. Deciding upon the finest type of rifle glass is based around what type of shooting you plan on doing.

First Focal Plane Optic Info

Focal plane scopes (FFP) feature the reticle in front of the magnification lens. These kinds of scopes are beneficial for:

  • Quick acquisition, long distance types of shooting
  • Shooting situations where calculations are small
  • Experienced shooters who know their target “hold over” and also “lead” correlations for their firearm
  • Shooters who do not mind the reticle is enlarged and uses up more visual eyesight space than a SFP reticle

Second Focal Plane Glass Facts

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 would be 1/5th of the non “zoom” tick.

  • Long distance forms of shooting where shooters have additional time to make ballistic calculations
  • Shooting where most of the shots occur within shorter proximities and ranges
  • Shooters who like a clearer optic sight picture without space taken up by the larger size FFP reticle

Zoom for Glass

The quantity of scope magnification you need on your optic depends upon the style of shooting you want to do. Just about every style of rifle optic offers some amount of magnification. The amount of zoom a scope supplies is identified by the size, density, and curves of the lenses inside of the rifle optic. The magnification of the optic is the “power” of the opic. This means what the shooter is aiming at through the scope is magnified times the power aspect of what can normally be seen by human eyes.

Fixed Power Lens Rifle Optics

A single power rifle scope comes with a magnification number designator like 4×32. This means the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not adjust considering that it is a fixed power optic.

Info About Variable Power Lens Rifle Glass

Variable power rifle scopes use enhanced power. The power change is achieved by making use of the power ring part of the scope near the rear of the scope by the eye bell.

The Power Level and Range of Rifle Glass

Here are some recommended scope power levels and the ranges where they could be efficiently used. High power glass will not be as effective as lower powered scopes since too much magnification can be a bad thing. The exact same idea relates to longer distances where the shooter needs enough power to see where to best aim the rifle at the target.

Lens Finishing for Rifle Glass

All contemporary rifle scope and optic lenses are layered. Lens coating can be a vital element of a shooting system when looking into high end rifle optics and scope systems.

HD Versus ED Lenses

Some glass makers additionally use “HD” or high-def glass finishings which employ various processes, polarizations, rare earth compounds, and components to enhance various colors and viewable definition through the lens. This high-definition finish is typically used with more costly, high density glass which brings down light’s potential to refract through the lens glass. Some scope brands use “HD” to refer to “ED” signifying extra-low dispersion glass. ED handles how colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is similarly called color distortion or fringing. Chromatic aberration can be noticeable over objects with well defined outlines as light hits the item from various angles.

Rifle Scope Lens Single Covering Versus Multi-Coating

Various optic lenses can likewise have different coatings applied to them. All lenses normally have at least some type of treatment or coating applied to them before they are used in a rifle scope or optic.

Single coated lenses have a treatment applied to them which is normally a protective and boosting multi-purpose treatment. This lens treatment can safeguard 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 manufacturer and the amount you paid for it. Both the manufacturer and amount are indications of the lens quality.

Some scope producers similarly make it a point to specify if their optic lenses are coated or “multi” coated. Being “much better” depends on the maker’s lens treatment innovation and the quality of materials used in constructing the rifle scope.

Hydrophobic Rifle Optic Lens Coating

Water on a scope lens does not support maintaining a clear sight picture through an optic in any way. Numerous top of the line and premium optic manufacturers 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 provides protection for the surface of the Steiner glass lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads slide off of the scope to maintain a clear, water free sight picture.

Scope Installation Choices

Mounting options for scopes are available in a few choices. There are the standard scope rings which are individually mounted to the scope and one-piece scope mounts which cradle the scope. These various types of mounts also normally are made in quick release versions which use throw levers which allow rifle shooters to rapidly mount and remove the scope.

Hex Key Rifle Scope Ring Mounting Solutions

Basic, clamp style mounting optic rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These styles of scope mounts use two independent rings to support the optic, and are normally constructed from 7075 T6 billet aluminum or similar materials which are manufactured for long distance precision shooting. This kind of scope mount is exceptional for rifles which need to have a long lasting, rock solid mount which will not shift despite just 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 optics system on a reach out and touch someone hunting or hard target interdiction firearm which will rarely need to be modified or recalibrated. Blue 242 Loctite threadlocker can additionally be used on the mount’s screws to keep the hex screws from backing out after they are installed firmly in place. An example of these mounting rings are the 30mm type from Vortex Optics. The set generally costs around $200 USD

Quick-Release Cantilever Rifle Scope Rings

These types of quick-release rifle scope mounts can be used to quickly detach a scope from a rifle and reattach it to a different rifle. If they all use a similar design mount, a number of scopes can often be swapped out. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top style Picatinny rail. This allows the scope to be sighted in while on the rifle, taken off of the rifle, and remounted back on the rifle while keeping accuracy. These kinds of mounts come in beneficial for rifles which are transferred a lot, to take off the scope glass from the rifle for protection, or for sight systems which are utilized in between several rifles. An example of this mount style is the 30mm mount designed by Vortex Optics. It usually costs around $250 USD

Info Around Rifle Scope Tube Sealing and Gas Purging

Moisture inside your rifle scope can destroy a day on the range and your costly optic by triggering fogging and developing residue within the scope’s tube. Most scopes protect against wetness from getting in the optical tube with a series of sealing O-rings which are water resistant. Normally, 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 ample moisture content avoidance for conventional use rifles, unless you plan on taking your rifle on boats and are concerned about the scope still working if it falls overboard and you can still find the rifle.

Info on Scope Tube Gas Purging

Another component of preventing the buildup of wetness inside of the rifle optic tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the optic is less influenced by temperature level changes and pressure differences from the outdoor environment which may potentially allow water vapor to leak in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a good rifle scope to look for.
