Hammers 30mm Tube 3X Magnifier Scope for Red Dot Reflex Sight
A great add-on to tactical red dot sights. It converts the sights instantly into a sighting system for longer range targeting and sniping. Sometimes the combination use of red dot sight and magnifier scope will have the dot reticle out of center in the field of view of the magnifier due to natural slight misalignment of optical axis between the sight and the magnifier. This professional grade Hammers magnifier scope is adjustable for windage and elevation to better align with the red dot sight without changing the actual ZERO of the sight. 30mm main tube of the magnifier works with standard 30mm scope mount of desired center height that matches that of the red dot sight. Rubber armored turret and grip area. It would be the best if you could get one of those flip mounts that rotate to stay on and off line of sight quickly. It is just that you need to be sure the center height of the mount used matches that of the red dot sight. Specifications: Magnification: 3x. Eye relief: 50mm (2inch) Weight:7.8oz. Overall length: 4 1/2inch. Accessories: lens covers

What You Need to Know About Rifle Glass
Rifle scopes allow you to exactly align a rifle at various targets by aligning your eye with the target over a range. They accomplish this through magnifying the target by using a set of lenses within the scope. The scope’s alignment can be dialed in to account for separate ecological elements like wind speed and elevation decreases to account for bullet drop.
The scope’s purpose is to help shooters understand precisely where the bullet will land based on the sight picture you are seeing with the scope as you line up the scope’s crosshair or reticle with the target. Most contemporary rifle scopes have around eleven parts which are located inside and externally on the scope. These scope parts include the rifle scope’s body, lenses, modification dials or turrets, objective focus rings, and other parts. See all eleven parts of a scope.
About Optic Types
Rifle scopes can be either “first focal plane” or “second focal plane” type of scopes. The form of focal plane a scope has identifies where the reticle or crosshair lies in connection with the optic’s zoom. It actually suggests the reticle is located behind or in front of the magnifying lens of the scope. Selecting the most beneficial type of rifle optic is based on what kind of hunting or shooting you intend on doing.
First Focal Plane Scope Details
Focal plane scopes (FFP) feature the reticle in front of the magnifying lens. This causes the reticle to increase in size based on the extent of magnification being used. The benefit is that the reticle measurements are the same at the magnified distance as they are at the non magnified distance. For example, one tick on a mil-dot reticle at one hundred yards without having “zoom” is still the corresponding tick at 100 yards using 5x “zoom”. These kinds of scopes work for:
- Quick acquisition, far away types of shooting
- Shooting circumstances where estimations are marginal
- Experienced shooters who have an idea for their aim point “hold over” and also “lead” correlations for their firearm
- Shooters who do not mind the reticle is bigger and occupies more visual eyesight area than a SFP reticle
Second Focal Plane Optic Facts
Second focal plane optics (SFP) include the reticle to the rear of the zoom 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 measurement.
- Far away styles of shooting where shooters have more time to make ballistic computations
- Shooting where most of the shots take place within shorter ranges and proximities
- Shooters who would like a clearer optic picture with less space used up by the larger sized FFP reticle
Ins and Outs of Rifle Optic Zoom
The level of scope zoom you need on your optic is based on the form of shooting you like to do. Just about every kind of rifle optic gives some amount of zoom. The amount of magnification a scope gives is determined by the diameter, density, and curves of the lenses within the rifle scope. The zoom of the optic is the “power” of the scope. This indicates what the shooter is checking out through the scope is amplified times the power element of what can typically be seen by human eyes.
Single Power Lens Optic Info
A single power rifle scope uses a magnification 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 fluctuate considering that it is a fixed power scope.
Adjustable Power Lens Glass Details
Variable power rifle scopes use variable power levels. The power modification is accomplished by the power ring part of the scope near the back of the scope by the eye bell.
The Power Level and Range of Rifle Optics
Here are some suggested scope power levels and the distances where they could be efficiently used. High power glass will not be as useful as lower magnification glass because too much zoom can be a negative aspect depending on your shooting distance. The exact same concept applies to extended ranges where the shooter needs to have sufficient power to see precisely where to best aim the rifle at the target.
Details on Lens Finishing
All modern rifle scope lenses are layered. There are various types and qualities of glass finishes. Lens covering is a crucial element of a rifle when looking into high-end rifle optics and scope systems. The lenses are one of the most vital pieces of the glass since they are what your eye sees through while sighting a rifle in on the point of impact. The finish on the lenses shields the lens surface area and helps with anti glare capabilities from refracted natural light and color perception.
HD Versus ED Optic Lens Coatings
Some glass companies additionally use “HD” or high-def glass coverings which apply various processes, components, chemicals, and polarizations to enhance various colors and viewable target definition through the lens. This HD finishing is often used with more costly high density glass which lowers light’s potential to refract through the lens glass. Some scope corporations use “HD” to refer to “ED” suggesting extra-low dispersion glass. ED deals with how certain colors are presented on the chroma spectrum and the chromatic aberration which is also called color distortion or fringing. Chromatic aberration may be visible over objects with well defined outlines as light hits the item from certain angles.
What to Know About Single Coating Versus Multi-Coating
Various optic lenses can also have different coverings used to them. All lenses generally have at least some type of treatment or finish used to them prior to being used in a rifle scope or optic.
Single coated lenses have a treatment applied to them which is usually a protective and boosting multi-purpose treatment. This lens treatment can preserve the lens from scratches while decreasing glare and other less advantageous things experienced in the shooting environment while sighting in with the optic. The quality of a single coated lens depends upon the scope developer and the amount you spent for it. Both are indications of the lens quality.
Some scope producers similarly make it a point to specify if their optic lenses are layered or “multi” covered. Being “better” depends on the maker’s lens treatment innovation and the quality of materials used in developing the rifle scope.
Info on Hydrophobic Finishing
Water on an optical lens doesn’t improve maintaining a clear sight picture through a scope at all. Numerous top of the line or premium scope manufacturers will coat their lenses with a hydrophilic or hydrophobic coating. The Steiner Optics Nano-Protection is a good example of this sort of treatment. It treats the exterior surfaces of the Steiner optic lens so the H2O particles can not bind to it or create surface tension. The result is that the water beads roll off of the scope to keep a clear, water free sight picture.
Options for Mounting Rifle Scopes on Long Guns
Installing options for scopes come in a few choices. There are the standard scope rings which are individually mounted to the optic and one-piece scope mounts which cradle the scope. These various kinds of mounts also normally are made in quick release versions which use manual levers which permit rifle shooters to quickly mount and remove the scope.
Hex Key Rifle Optic Rings
Normal, clamp design mounting scope rings use hex head screws to mount to the flattop design Picatinny scope mount rails on rifles. These types of scope mounts use a couple of different rings to support the optic, and are made from 7075 T6 billet aluminum which are created for long range precision shooting. This type of scope mount is great for rifles which need a resilient, rock solid mounting solution which will not move no matter how much the scope is moved or abuse the rifle takes.
Rifle Scope Mounting Solutions with Quick-Release Cantilever 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. Several scopes can also be swapped out if they all use a complementary designed mount. The quick detach mount style is CNC crafted from anodized 6061 T6 aluminum and the mounting levers fasten nicely to a flat top design Picatinny rail. This allows the scope to be sighted in while on the rifle, removed from the rifle, and remounted while retaining the original sighting settings. These kinds of mounts are useful and beneficial for rifles which are transferred between vehicles a lot, to remove the scope glass from the rifle for protection, or for optics which are employed between several rifles. An example of this mount style is the 30mm mount designed by the Vortex Optics manufacturer. It usually costs around $250 USD
Details on Optic Tube Sealing and Gas Purging
Moisture inside your rifle glass can ruin a day of shooting and your costly optic by inducing fogging and generating residue inside of the scope tube. A lot of scopes protect against moisture from going into the scope tube with a series of sealing O-rings which are waterproof. Generally, these scopes can be immersed beneath 20 or 30 feet of water before the water pressure can push moisture past the O-rings. This should be plenty of moisture prevention for standard use rifles for hunting and sporting purposes, unless you plan on taking your rifle sailing and are concerned about the scope still performing if it goes over the side and you can still rescue the firearm.
Scope Gas Purging
Another part of preventing the buildup of wetness within the rifle optic tube is filling the tube with a gas like nitrogen. Because this area is already taken up by the gas, the optic is less affected by condition changes and pressure variations from the outdoor environment which could possibly permit water vapor to seep in around the seals to fill the void which would otherwise exist. These are good qualities of a decent rifle scope to look for.
