Nikon PROSTAFF 7 2.5-10×42 BDC
Low-light situations require superior glass and light gathering ability. Nikon’s new PROSTAFF 7 riflescope has all the features to ensure a successful hunt ” especially in those crucial times near dawn and dusk. Built with Nikon’s high-quality Fully-Multicoated lenses, 30mm main body tubes and 4-time zoom magnification range, the PROSTAFF 7 riflescope is the latest winning product in the long line of Nikon Sport Optics. The BDC’s unique see-through ballistic circles offer an incredible advantage for long range shooting, yet allow a normal sight picture for shorter-range shots where the crosshair itself is the aiming point. The various aiming points built into the BDC reticle allows hunters to hold ‘dead-on’ at ranges exceeding those previously thought possible and can be utilized with Nikon’s Spot On Ballistic Match Technology to give you exact aiming points at various yardages.

Information Scopes
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target over a range. They do this through zoom using a series of lenses within the scope. The scope’s alignment can be adjusted for consideration of separate ecological considerations like wind and elevation to make up 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 viewing with the optic as you line up the scope’s crosshair or reticle with the intended target. A lot of contemporary rifle scopes and optics have around 11 parts which are found inside and on the exterior of the scope. These optic pieces consist of the rifle scope’s body, lenses, modification turrets or dials, objective focus rings, and other elements. See all eleven parts of scopes.
The Varieties of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” style of scopes. The form of focal plane a scope has decides where the reticle or crosshair lies in regard to the optic’s magnification. It literally implies the reticle is situated behind or ahead of the magnification lens of the optic. Choosing the very best style of rifle optic is based on what variety of hunting or shooting you anticipate undertaking.
First Focal Plane Glass Facts
Focal plane scopes (FFP) come with the reticle in front of the zoom lens. This triggers 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 enhanced distance as they are at the non amplified range. One tick on a mil-dot reticle at 100 yards without “zoom” is still the exact same tick at 100 yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are marginal
- Experienced shooters who know their aim point “hold over” plus “lead” correlations for their long gun
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight room than a SFP reticle
Info on Second Focal Plane Scopes
Second focal plane optics (SFP) include the reticle to the rear of the zoom lens. This causes the reticle to stay at the same scale in connection with the level of zoom being used. The outcome is that the reticle measurements change based upon the magnification chosen to shoot over longer distances due to the fact that the reticle markings represent various increments which differ with the zoom. In the FFP illustration with the SFP optic, the 5x “zoom” one hundred yard tick would be 1/5th of the non “zoom” tick. These types of glass work for:
- Long distance kinds of shooting where shooters have more time to make ballistic calculations
- Shooting where most shots happen within shorter spaces and ranges
- Shooters who choose a clearer optic sight picture with less area taken up by the bigger FFP reticle
Details on Scope Magnification
The quantity of magnification a scope provides is figured out by the size, thickness, and curvatures of the lenses inside of the rifle scope. The zoom of the scope is the “power” of the scope.
Fixed Power Lens Rifle Glass Facts
A single power rifle optic comes with a zoom number designator like 4×32. This indicates the zoom power of the scope is 4x power and the objective lens is 32mm. The magnification of this kind of scope can not change because it is set from the factory.
Adjustable Power Lens Glass
Variable power rifle scopes use enhanced power. The power change is handled by the power ring part of the scope near the rear of the scope by the eye bell.
The Power Level and Range of Scopes
Here are some advised scope powers and the ranges where they can be efficiently used. Highly magnified glass will not be as useful as lower powered scopes considering that too much magnification can be a bad thing. The same relates to longer distances where the shooter needs to have sufficient power to see precisely where to properly aim the rifle.
Info on Rifle Scope Lens Coverings
All top teir rifle scope and optic lenses are layered. Lens covering can be a vital element of a shooting system when considering high end rifle optics and scope setups.
HD Versus ED Lenses
Some optic manufacturers additionally use “HD” or high-def lens coatings that apply different procedures, chemicals, polarizations, and components to draw out a wide range of colors and viewable target definition through lenses. This high-definition finishing is often used with higher density glass which decreases light’s chance to refract by means of the lens glass. Some scope makers use “HD” to describe “ED” implying extra-low dispersion glass. ED deals with how certain colors are presented on the chromatic spectrum and the chromatic deviance or aberration which is also called color distortion or fringing. Chromatic aberration can be noticeable over things with well defined outlines as light hits the item from certain angles.
What to Know About Single Finishing Versus Multi-Coating
Various optic lenses can likewise have different finishes applied to them. All lenses generally have at least some type of treatment or covering used to them prior to being used in a rifle scope or optic.
Single layered lenses have a treatment applied to them which is normally a protective and enhancing multi-purpose treatment. This lens treatment can safeguard the lens from scratches while minimizing 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 designer and how much money you spent for it. Both the manufacturer and amount are indications of the lens quality.
Some scope manufacturers also make it a point to specify if their optic lenses are coated or “multi” covered. This implies the lens has had multiple treatments applied to them. If a lens receives numerous treatments, it can show that a maker is taking several steps to fight different environmental elements like an anti-glare finish, a scratch resistant anti-abrasion finish, followed by a hydrophilic finishing. This also doesn’t always imply the multi-coated lens is much better than a single coated lens. Being “much better” depends upon the maker’s lens treatment solutions and the quality of components used in creating the rifle optic.
Info on Hydrophobic Covering
Water on a scope’s lens doesn’t help with keeping a clear sight picture through a scope at all. Lots of top of the line or high-end optic producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a good example of this type of treatment. It provides protection for the exterior of the Steiner optic lens so the water particles can not bind to it or produce surface tension. The outcome is that the water beads slide off of the scope to keep a clear, water free sight picture.
Choices for Mounting Rifle Scopes on Long Guns
Mounting options for scopes are available in a couple of options. There are the standard scope rings which are separately mounted to the scope and one-piece scope mounts which cradle the scope. These various kinds of mounts also generally are made in quick release variations which use throw levers which permit rifle operators to rapidly mount and remove the optics.
Glass Mounting Solutions 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 developed for long range accuracy shooting. This type of scope install is wonderful for rifles which need a durable, sound mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Quick-Release Cantilever Rifle Glass Rings
These types of quick-release rifle scope mounts can be used to quickly remove 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 also be switched out. The quick detach design is CNC crafted from anodized 6061 T6 aluminum and the mounting levers attach tightly to a flat top style Picatinny rail. This permits the scope to be sighted in while on the rifle, removed from the rifle, and remounted back on the rifle while maintaining precision. These types of mounts are useful and convenient for rifles which are hauled around a lot, to take off the scope from the rifle for protection, or for sight systems which are chosen for use between several rifles. An example of this mount type is the 30mm mount designed by Vortex Optics. It normally costs around $250 USD
Sealing and Gas Purging for Optic Tubes
Moisture inside your rifle optic can destroy a day of shooting and your expensive optic by triggering fogging and producing residue inside of the scope tube. Many scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are waterproof.
Glass Gas Purging
Another part of preventing the buildup of wetness inside of the rifle scope tube is filling the tube with a gas like nitrogen. Considering that this area is currently taken up by the gas, the optic is less influenced by condition shifts and pressure variations from the outside environment which may possibly allow water vapor to permeate in around the seals to fill the vacuum which would otherwise be there. These are good qualities of a decent rifle scope to look for.
