Rifle Scope Product Features
About this item
A subset of the Viper HS line, the Viper HS LR (Hunting & Shooting Long Range) 4-16×44 Second Focal Plane scope is perfect for when you need to extend your shooting range and bullet drop and wind drift compensation are crucial.
The Dead-Hold BDC reticle is good for any hunting or shooting at varying ranges where estimating hold-over would be a concern.
In the advanced optical system, the XD glass renders an image that is sharp and clear from edge to edge. There are XR multi-coated lenses allowing you to capture the most light from dawn til dusk. The 4x zoom range will pull you close to your target.
The HS LR offers exposed target-style elevation turrets for dialing elevation at extended ranges. The CRS Zero Stop allows you to get back to referencing zero even after coming up several revolutions on the turret.
Ultra-hard, scratch resistant Armortek coatings protect the exterior lenses of the scope. Argon purging provides fogproof and waterproof performance. The hard-anodized matte black finish is extremely durable and looks awesome too.

About Optics
Rifle scopes enable you to specifically aim a rifle at various targets by lining up your eye with the target over a range. They do this through zoom by using a series of lenses inside the scope. The scope’s alignment can be adjusted to account for many ecological factors like wind and elevation decreases to account for bullet drop.
The scope’s purpose is to understand exactly where the bullet will land based on the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the target. Many contemporary rifle scopes have about 11 parts which are located within and on the exterior of the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment dials, objective focus rings, and other components. See all eleven parts of scopes.
Rifle Glass Varieties
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The style of focal plane an optic has establishes where the reticle or crosshair lies relative to the optic’s zoom. It actually indicates the reticle is behind or ahead of the magnification lens of the optic. Looking for the most suitable type of rifle optic depends on what type of hunting or shooting you anticipate undertaking.
Info About First Focal Plane Glass
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This triggers the reticle to increase in size based upon the amount of magnification being used. The outcome is that the reticle measurements are the same at the enhanced range as they are at the non magnified range. For example, one tick on a mil-dot reticle at one hundred yards with no “zoom” is still the very same tick at 100 yards with 5x “zoom”. These types of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting situations where calculations are minor
- Experienced shooters who understand their target “hold over” and also “lead” relationships for their long gun
- Shooters who don’t mind the reticle is enlarged and takes up more visual sight room than a SFP reticle
Second Focal Plane Glass Info
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” 100 yard tick measurement would be 1/5th of the non “zoom” tick measurement.
- Long distance kinds of shooting where shooters have additional time to make ballistic computations
- Shooting where most shots take place within shorter spaces and ranges
- Shooters who like a clearer optic sight picture without area taken up by the enlarged FFP reticle
Zoom for Scopes
The amount of magnification a scope supplies is identified 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.
Single Power Lens Optics
A single power rifle optic or scope uses 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 kind of optic can not change since it is a set power scope.
Variable Power Lens Scope Info
Variable power rifle scopes use variable power levels. The power adjustment is handled by making use of the power ring part of the scope near the back of the scope by the eye bell.
Power and Range
Here are some suggested scope powers and the ranges where they could be effectively used. Remember that higher magnification optics and scopes will not be as practical as lower powered scopes because excessive magnification can be a bad thing. The exact same idea goes for extended distances where the shooter needs to have enough power to see where to properly aim the rifle.
Info on Rifle Scope Lens Finish
All contemporary rifle scope and optic lenses are coated. There are various types and qualities of glass finishings. When researching high end rifle targeting systems, Lens finishing can be a critical element of a rifle. The lenses are among the most essential pieces of the optic since they are what your eye looks through while sighting a rifle in on the target. The finishing on the lenses safeguards the lens surface and even assists with anti glare capabilities from excess daylight and color discernibility.
About Lens Coatings – HD Versus ED
Some scope makers likewise use “HD” or high-definition lens finishes which use various techniques, elements, chemicals, and polarizations to draw out various colors and viewable definition through the lens. Some scope producers use “HD” to refer to “ED” meaning extra-low dispersion glass.
Single Covering Versus Multi-Coating for Rifle Scopes
Different optic lenses can also have different coatings applied to them. All lenses generally have at least some type of treatment or finishing applied to them prior to being used in a rifle scope or optic.
This lens treatment can safeguard the lens from scratches while decreasing glare and other less beneficial things experienced in the shooting environment while sighting in with the scope. The quality of a single covered lens depends on the scope maker and how much you paid for it.
Some scope manufacturers also make it a point to define if their optic lenses are layered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of products used in developing the rifle scope.
Hydrophobic Lens Finishes
Water on an optic’s lens doesn’t assist with maintaining a clear sight picture through a scope in any way. Lots of top of the line or high-end scope producers will coat their lenses with a hydrophilic or hydrophobic covering. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with the surface of the Steiner glass lens so the H2O molecules can not bind to it or develop surface tension. The outcome is that the water beads roll off of the scope to keep a clear, water free sight picture.
Rifle Glass Installation Options
Mounting approaches for scopes are available in a few choices. There are the basic scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various types of mounts also generally can be found in quick release variations which use manual levers which permit rifle shooters to rapidly install and remove the glass.
Hex Key Rifle Scope Ring Mounts
Standard, clamp style 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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which are developed for long distance precision shooting. This type of scope install is fine for rifles which need a long lasting, rock solid mount which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Rifle Glass Ring Mounts
These types of quick-release rifle scope mounts can be used to rapidly detach a scope and attach it to a different rifle. Numerous scopes can even be swapped out if they all use a compatible design mount. These types of mounts come in handy for rifle platforms which are transferred a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between multiple rifles.
Details on Glass Tube Sealing and Gas Purging
Moisture inside your rifle scope can ruin a day of shooting and your costly optic by bringing about fogging and developing residue inside of the scope tube. A lot of scopes prevent wetness from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Rifle Scope Tubes
Another component of preventing the buildup of wetness within the rifle optic’s tube is filling the tube with a gas like nitrogen. Considering that this space is already taken up by the gas, the scope is less altered by temp alterations and pressure differences from the outside environment which could possibly enable 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.
