Nightforce Optics 12-42x56mm BR Benchrest Series Riflescope, Matte Black Finish with Illuminated NP-R2 Reticle.125 MOA Adjustments, Adjustable Objective, 30mm Tube
Since 1992, Nightforce riflescopes have won more records in long-range benchrest competition — including several world records in .50 B.M.G. 1000 yard benchrest — than any other scope on the market. Both Precision Benchrest models include an externally adjustable illuminated reticle, true .125 M.O.A. click values and a broad range of internal adjustment. These are not “dual-purpose” or hunting scopes with a different name. Each was designed and built from the ground up to answer the specific demands of the long-range benchrest shooter. Each of our Precision Benchrest models feature 56mm multi-coated lenses, providing the superior resolution necessary to distinguish fine detail at extremely long ranges. An adjustable objective allows extra-fine focus to adjust parallax from 25 yards to infinity. Target turrets are calibrated in true .125 M.O.A. (1/8 click) values and can be re-indexed to zero after sighting in. Both Precision Benchrest riflescopes are equipped with a coil spring plunger return system to maximize tracking accuracy. The eyepiece provides fast reticle focusing, and a glass-etched illuminated reticle provides optimum image/reticle contrast under virtually any lighting conditions. You have two choices of magnification ranges. But only one choice in the ultimate benchrest riflescopes

Glass Info
Rifle scopes permit you to exactly aim a rifle at different targets by aligning your eye with the target at range. They accomplish this through magnification by utilizing a series of lenses inside the scope. The scope’s positioning can be adjusted to account for different environmental elements like wind and elevation decreases to make up for bullet drop.
The scope’s purpose is to help the shooter understand exactly where the bullet will hit based upon the sight picture you are viewing via the optic as you align the scope’s crosshair or reticle with the intended point of impact. Most contemporary rifle optics have about 11 parts which are found internally and on the exterior of the optic. These scope parts include the rifle scope’s body, lenses, modification turrets or dials, focus rings, and other elements. See all eleven parts of a rifle scope.
Rifle Scope Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding on the optimal type of rifle glass depends on what type of shooting you plan to do.
First Focal Plane Optic Facts
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This induces the reticle to increase in size based on the amount of zoom being used. The result is that the reticle measurements are the same at the magnified distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the same tick at 100 yards with 5x “zoom”. These kinds of scopes are useful for:
- Quick acquisition, long distance kinds of shooting
- Shooting situations where computations are marginal
- Experienced shooters who have an idea for their aim point “hold over” as well as “lead” ratios for their long gun
- Shooters who don’t mind the reticle is enlarged and uses up more visual sight room than a SFP reticle
About Second Focal Plane Scopes
Second focal plane optics (SFP) come with the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement.
- Far away styles of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within shorter ranges and spaces
- Shooters who desire a clearer optic picture with less space used up by the bigger FFP reticle
Zoom for Glass
The measure of scope magnification you need is based on the kind of shooting you want to do. Just about every type of rifle glass supplies some degree of magnification. The volume of zoom a scope delivers is determined by the diameter, density, and curvatures of the lens glass inside of the rifle scope. The zoom of the optic is the “power” of the opic. This signifies what the shooter is looking at through the scope is magnified times the power factor of what can generally be seen by human eyes.
Single Power Lens Glass
A single power rifle optic 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 zoom of this type of optic can not change considering that it is a set power scope.
Info About Adjustable Power Lens Optics
Variable power rifle scopes use variable power levels. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Optics
Here are some recommended scope powers and the ranges where they could be effectively used. Keep in mind that high magnification scopes and optics will not be as effective as lower magnification level scopes due to the fact that excessive zoom can be a detractor. The very same idea goes for extended ranges where the shooter needs increased power to see precisely where to properly aim the rifle.
Details on Lens Coverings
All contemporary rifle optic and scope lenses are layered. There are different types and qualities of glass lens finishings. Lens covering can be a crucial element of a rifle when considering high-end rifle optics and targeting systems. The glass lenses are one of the most key parts of the optic considering that they are what your eye looks through while sighting a rifle in on the point of impact. The covering on the lenses protects the lens surface area and even improves anti glare from refracted light and color perception.
ED Versus HD Rifle Glass
Some rifle glass manufacturers will also use “HD” or high-def glass finishes that apply different procedures, components, polarizations, and chemical applications to enhance various colors and viewable target visibility through the lens. This high-definition finish is normally used with more costly high density lens glass which lowers light’s chance to refract through the lens glass. Some scope corporations use “HD” to describe “ED” indicating extra-low dispersion glass. ED handles how certain colors are presented on the chromatic spectrum and the chromatic aberration or deviance which is also called color distortion or fringing. Chromatic aberration can be noticeable around objects with well defined shapes as light hits the object from various angles.
Single Finish Versus Multi-Coating
Different scope lenses can also have various coverings applied to them. All lenses generally have at least some type of treatment or finish applied to them prior to being used in a rifle scope or optic. Since the lens isn’t simply a raw piece of glass, they require performance enhancing coatings. It is part of the carefully tuned optic. It requires a coating to be applied to it so that the lens will be efficiently usable in many kinds of environments, degrees of sunshine (full VS shade), and other shooting conditions.
This lens treatment can protect the lens from scratches while decreasing glare and other less helpful 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 manufacturers also make it a point to specify if their optic lenses are covered or “multi” coated. Being “better” depends on the manufacturer’s lens treatment technology and the quality of materials used in constructing the rifle scope.
Optic Lens Anti-water Finishing
Water on an optic’s lens doesn’t improve keeping a clear sight picture through a scope at all. Lots of top of the line or premium optic makers will coat their lenses with a hydrophobic or hydrophilic finish. The Steiner Optics Nano-Protection is a good example of this kind of treatment. It deals with the surface 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 roll off of the scope to keep a clear, water free sight picture.
Alternatives for Mounting Rifle Scopes on Long Guns
Mounting options for scopes are available in a few choices. There are the basic scope rings which are separately mounted to the optic and one-piece mounts which cradle the scope. These different kinds of mounts also usually come in quick release variations which use manual levers which allow rifle shooters to rapidly install and remove the scopes.
Hex Key Rifle Optic Ring Mounts
Basic, clamp-on style mounting scope rings use hex head screws to mount to the flattop style Picatinny scope mounting rails on rifles. These styles of scope mounts use a pair of independent rings to support the scope, and are normally made from 7075 T6 billet aluminum which are made for long distance precision shooting. This kind of scope mount is excellent for rifle systems which need a long lasting, hard use mount which will not move despite how much the scope is moved or abuse the rifle takes. These are the design of mounts you really want to have for a faithful optics setup on a reach out and touch someone hunting or competitors firearm which will pretty much never need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on the scope mount 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 style from Vortex Optics. The set usually costs around $200 USD
Scope Mounting Solutions with Quick-Release Cantilever Rings
These kinds of quick-release rifle scope mounts can be used to rapidly remove a scope from a rifle and reattach it to a different rifle. Several scopes can also be switched out if they all use a similar style mount. The quick detach design is CNC machined from anodized 6061 T6 aluminum and the mounting levers attach nicely to a flat top design Picatinny rail. This enables the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These kinds of mounts are useful and convenient for rifles which are moved a lot, to remove the scope from the rifle for protection, or for scopes which are used in between several rifles. An example of this mount style 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 glass can destroy a day of shooting and your costly optic by inducing fogging and generating residue inside of the scope’s tube. The majority of scopes prevent moisture from going into the optical tube with a series of sealing O-rings which are water resistant. Usually, these optics can be immersed under 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of humidity avoidance for standard use rifles for hunting and sporting purposes, unless you intend on taking your rifle sailing and are concerned about the optic still functioning if it goes overboard and you can still salvage the firearm.
Gas Purged Rifle Scope Tubes
Another element of preventing the buildup of moisture inside of the rifle scope’s tube is filling the tube with a gas like nitrogen. Given that this space is currently taken up by the gas, the scope is less affected by temperature shifts and pressure distinctions from the external environment which could potentially enable 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 seek out.
