What You Need to Know About Rifle Glass
Rifle scopes enable you to exactly align a rifle at various targets by aligning your eye with the target over a distance. They do this through zoom using a set of lenses inside the scope. The scope’s alignment can be adapted for consideration of various natural factors like wind and elevation increases or decreases to make up for bullet drop.
The scope’s function is to help shooters understand precisely where the bullet will hit based upon the sight picture you are seeing using the optic as you align the scope’s crosshair or reticle with the target. The majority of modern rifle scopes and optics have around eleven parts which are located within and externally on the scope body. These scope parts consist of the rifle scope’s body, lenses, adjustment turrets, objective focus rings, and other parts. Learn about the eleven parts of glass.
The Styles of Rifle Scopes
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. Deciding upon the perfect type of rifle glass is based around what type of shooting you plan to do.
First Focal Plane Optics
Focal plane scopes (FFP) come with the reticle in front of the magnifying lens. This causes the reticle to increase in size based upon the extent of magnification being used. The result 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 one hundred yards with no “zoom” is still the very same tick at one hundred yards with 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away kinds of shooting
- Shooting scenarios where estimations are marginal
- Experienced shooters who understand their target “hold over” and also “lead” equations for their weapon
- Shooters who don’t mind the reticle is bigger and occupies more visual sight area than a SFP reticle
Info About Second Focal Plane Scopes
Second focal plane optics (SFP) feature the reticle behind the magnifying lens. This induces the reticle to stay at the exact same dimensions relative to the volume of zoom being used. The result is that the reticle dimensions change based on the magnification chosen to shoot over lengthier ranges because the markings represent various increments which fluctuate with the magnification level. In the FFP example with the SFP glass, the 5x “zoom” 100 yard tick reticle measurement would be 1/5th of the non “zoom” tick measurement. These sorts of optics are convenient for:
- Long distance styles of shooting where shooters have more time to make ballistic estimations
- Shooting where most shots happen within shorter ranges and distances
- Shooters who desire a clearer optic sight picture with less space used up by the bigger FFP reticle
Rifle Optic Zoom
The amount of scope zoom you need on your scope is based on the kind of shooting you desire to do. Almost every style of rifle glass gives some degree of magnification. The level of zoom a scope delivers is determined by the diameter, thickness, and curves of the lenses inside of the rifle optic. The magnifying level of the scope is the “power” of the glass. This denotes what the shooter is aiming at through the scope is magnified times the power factor of what can usually be seen by human eyes.
Info on Fixed Single Power Lens Rifle Scopes
A single power rifle optic will have a magnification number designator like 4×32. This implies the zoom power of the scope is 4x power and the objective lens is 32mm. The zoom of this kind of scope can not change considering that it is set from the factory.
Variable Power Lens Rifle Optics
Variable power rifle scopes have adjustable power. These types of scopes will note the zoom amount in a configuration such as 2-10×32. These numbers imply the zoom of the scope can be set in between 2x and 10x power. This always includes the powers in-between 2 and 10. The power adjustment is achieved utilizing the power ring component of the scope near the back of the scope by the eye bell.
Glass Power Level and Ranges
Here are some advised scope power levels and the ranges where they could be efficiently used. Remember that high magnification optics will not be as effective as lower magnification level glass due to the fact that too much zoom can be a detractor. The same concept goes for longer distances where the shooter needs enough power to see exactly where to properly aim the rifle.
Optic Lens Finish
All modern rifle scope lenses are layered. Lens covering can be a crucial aspect of a rifle’s setup when looking at high end rifle optics and scope equipment.
ED Versus HD Glass
Some scope producers also use “HD” or high-definition lens coverings which use different processes, chemicals, polarizations, and elements to draw out different colors and viewable definition through the lens. Some scope makers use “HD” to refer to “ED” indicating extra-low dispersion glass.
Single Rifle Glass Lens Covering Versus Multi-Coating
Various optic lenses can likewise have various finishes used to them. All lenses normally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
This lens treatment can offer protection to the lens from scratches while decreasing glare and other less useful 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 producers likewise make it a point to define if their optic lenses are covered or “multi” coated. This implies the lens has numerous treatments applied to the surfaces of the glass. If a lens receives multiple treatments, it can prove that a company is taking numerous actions to combat different natural elements like an anti-glare finishing, a scratch resistant anti-abrasion covering, followed by a hydrophilic finishing. This also does not necessarily imply the multi-coated lens is better than a single coated lens. Being “better” depends on the manufacturer’s lens treatment technology and the quality of components used in constructing the rifle glass.
About Anti-water Coating
Water on a lens does not improve preserving a clear sight picture through an optic whatsoever. Many top of the line and high-end scope 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 treats the exterior of the Steiner optic lens so the water molecules can not bind to it or develop surface tension. The result is that the water beads move off of the scope to keep a clear, water free sight picture.
Choices for Mounting Rifle Optics on Long Guns
Mounting approaches for scopes come in a few options. There are the standard scope rings which are individually mounted to the optic and one-piece mounts which cradle the scope. These various kinds of mounts also usually are made in quick release variations which use manual levers which enable rifle shooters to quickly install and dismount the scope.
Hex Key Optic Ring Mounts
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 different rings to support the optic, and are often made from 7075 T6 billet aluminum which is developed for long distance accuracy shooting. This type of scope install is fine for rifles which need a durable, rock solid mounting solution which will not move no matter how much the scope is moved or abused.
Quick-Release Cantilever Glass Rings
These types of quick-release rifle scope mounts can be used to rapidly connect and detach a scope from a rifle before reattaching it to a different rifle. Several scopes can also be swapped out if they all use a similar style mount. These types of mounts come in handy for rifles which are transferred a lot, to swap out the optic from the rifle for protecting the scope, or for optics which are used between numerous rifles or are situationally focused.
Details on Glass Tube Sealing and Gas Purging
Wetness inside your rifle optic can mess up a day of shooting and your costly optic by causing fogging and creating residue inside of the scope tube. Many scopes prevent moisture from entering the scope tube with a system of sealing O-rings which are waterproof.
Gas Purged Optic Tubes
Another part of avoiding the accumulation of wetness within the rifle scope tube is filling the tube with a gas like nitrogen. Given that this area is already occupied by the gas, the scope is less altered by temp alterations and pressure variations from the external environment which might possibly enable water vapor to leak in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
