What You Need to Know About Rifle Optics
Rifle scopes permit you to precisely align a rifle at various targets by aligning your eye with the target over a distance. They accomplish this through magnifying the target by employing a set of lenses within the scope. The scope’s positioning can be adjusted to take into account many ecological factors like wind speed and elevation decreases to make up for bullet drop.
The scope’s function is to understand precisely where the bullet will hit based upon the sight picture you are seeing through the optic as you line up the scope’s crosshair or reticle with the target. Most modern rifle scopes have about 11 parts which are arranged within and on the exterior of the scope body. These optic pieces include the rifle scope’s body, lenses, adjustment turrets or dials, focus rings, and other parts. Learn about the eleven parts of rifle scopes.
Rifle Glass Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Considering the optimal type of rifle scope is based around what type of shooting you plan to do.
About First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnification lens. This triggers the reticle to increase in size based on the amount of magnification being used. The benefit is that the reticle measurements are the same at the magnified range as they are at the non magnified range. One tick on a mil-dot reticle at 100 yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These types of scopes are useful for:
- Quick acquisition, far away kinds of shooting
- Shooting circumstances where computations are minimal
- Experienced shooters who know their aim point “hold over” and “lead” equations for their long guns
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
About Second Focal Plane Optics
Second focal plane optics (SFP) feature the reticle to the rear of the magnification lens. In the FFP example with the SFP scope, the 5x “zoom” one hundred yard tick measurement would be 1/5th of the non “zoom” tick.
- Far away forms of shooting where shooters have extra time to make ballistic estimations
- Shooting where most of the shots occur within shorter ranges and proximities
- Shooters who want a clearer optic picture with less area taken up by the bigger FFP reticle
Zoom for Rifle Optics
The amount of scope zoom you require is based on the kind of shooting you like to do. Almost every type of rifle scope delivers some level of magnification. The quantity of zoom a scope gives is determined by the dimension, density, and curves of the lenses inside of the rifle optic. The magnification level of the optic is the “power” of the glass. This denotes what the shooter is aiming at through the scope is amplified times the power factor of what can usually be seen by human eyes.
Single Power Lens Glass
A single power rifle optic and scope uses a zoom number designator like 4×32. This implies the magnification power of the scope is 4x power while the objective lens is 32mm. The zoom of this kind of scope can not change since it is fixed.
Adjustable Power Lens Rifle Optics
Variable power rifle scopes use enhanced power. The power adjustment is accomplished using the power ring part of the scope near the back of the scope by the eye bell.
Power and Range Correlations
Here are some recommended scope powers and the ranges where they may be successfully used. Highly magnified rifle scope glass will not be as beneficial as lower powered rifle scope glass considering that too much magnification can be a bad thing. The same relates to extended ranges where the shooter needs to have increased power to see where to best aim the rifle at the target.
Info on Glass Lens Coatings
All cutting-edge rifle optic and scope lenses are covered. Lens finishing can be an essential element of a rifle’s setup when buying high end rifle optics and scope setups.
HD Versus ED Optic Lens Coatings
Some scope makers also use “HD” or high-definition lens coverings which use various procedures, polarizations, chemicals, and elements to draw out various colors and viewable definition through the lens. Some scope manufacturers use “HD” to refer to “ED” implying extra-low dispersion glass.
Rifle Scope Lens Single Finish Versus Multi-Coating
Various optic lenses can likewise have various coverings applied to them. All lenses usually have at least some type of treatment or finish used to them before being used in a rifle scope or optic.
Single covered lenses have a treatment applied to them which is generally a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while minimizing 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 producer and just how much you paid for it. Both are indicators of the lens quality.
Some scope producers likewise make it a point to specify if their optic lenses are layered or “multi” coated. This suggests the lens has multiple treatments applied to them. If a lens gets several treatments, it can prove that a maker is taking multiple actions to fight different natural elements like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic covering. This additionally doesn’t necessarily suggest the multi-coated lens will perform better than a single coated lens. Being “much better” is dependent on the maker’s lens treatment solutions and the quality of materials used in creating the rifle scope.
Anti-water Rifle Scope Lens Finishing
Water on a lens does not improve maintaining a clear sight picture through an optic at all. Lots of top of the line or high-end scope manufacturers will coat their lenses with a hydrophilic or hydrophobic finishing. The Steiner Optics Nano-Protection is a fine example of this kind of treatment. It deals with 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 maintain a clear, water free sight picture.
Choices for Mounting Glass on Firearms
Mounting solutions for scopes can be found in a couple of choices. There are the basic scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These different types of mounts also generally come in quick release variations which use manual levers which enable rifle shooters to quickly install and dismount the optics.
Rifle Scope Mounting Solutions with Hex Key Rings
Standard, clamp-on type mounting optic rings use hex head screws to fix to the flattop style Picatinny scope mounting rails on rifles. These varieties of scope mounts use a pair of independent rings to support the scope, and are made from 7075 T6 billet aluminum which are made for far away accuracy shooting. This kind of scope mount is effective for rifle systems which are in need of a long lasting, unfailing mount which will not move despite just how much the scope is moved or jarring the rifle takes. These are the style of mounts you should get for a specialized scope setup on a far away scouting or sniper competition rifle that will rarely need to be altered or adjusted. Blue 242 Loctite threadlocker can also be used on screws to prevent the hex screws from wiggling out after they are mounted firmly in position. An example of these rings are the 30mm type made by Vortex Optics. The set typically costs around $200 USD
Quick-Release Cantilever Rifle Optic Ring Mounting Solutions
These types of quick-release rifle scope mounts can be used to rapidly connect and remove a scope from a rifle before reattaching it to a different rifle. Multiple scopes can also be switched out if they all use a compatible style mount. These types of mounts come in handy for rifle platforms which are transported a lot, to swap out the optic from the rifle for protection, or for scopes which are used in between numerous rifles or are situationally focused.
Details on Rifle Optic Tube Sealing and Gas Purging
Wetness inside your rifle optic can destroy a day of shooting and your expensive optic by causing fogging and developing residue inside of the scope tube. A lot of scopes prevent moisture from getting in the scope tube with a system of sealing O-rings which are water resistant.
Gas Purged Scope Tubes
Another component of preventing the buildup of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Because this area is currently taken up by the gas, the scope is less impacted by temp shifts and pressure differences from the external environment which may 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 look for.
