Frequently asked questions about CenterPoint® optics products...
What is the magnification?
ANSWER: These are the numbers before the x. For example 4x32 is a 4power magnification, meaning items viewed through the scope are 4x their size. Or, the 4-16x56 is a variable power scope, with adjustable magnification from 4x to 16x.
- Low power riflescopes are ideal at close range and for shooting moving targets.
- Medium power riflescopes are ideal for hunting big game targets at medium range.
- High power riflescopes are ideal for shooting, when the target is motionless and for varmints and other small game.
What size is the objective?
ANSWER: The objective lens is the end opposite the end you look through. The last number (3-9x40) is the diameter of the objective lens in millimeters. The larger the objective lens, the more light that can pass through it and the brighter the image at a given magnification. As power increases, the need for light also increases; otherwise you'll be looking at a large dark shadow. That's why high-powered scopes have large objective lenses. A 4x32 is brighter than a 12x40.
What is adjustable objective (AO) and what is the benefit of it?
ANSWER: Scopes that come with the adjustable objective will have a rotating ring on the front objective bell or an adjustment knob on the side opposite the windage dial. It allows the shooter to adjust for the distance they are shooting. A scopes adjustment range depends on the magnification. For example, the CenterPoint 6x32mm (CP632AORG) is adjustable from 3yds to infinity.
A scope that does not have AO is factory set for a specific distance (depending on the scope use) for example, the CenterPoint 3-9x40mm Tactical (CP394RC) is factory set at 100yds but the CenterPoint 3-9x32mm (CP3920 is factory set at 35yds. This is because the 3-9x32mm is geared toward airgun and .22's which are typically used for close range shooting.
Each scopes parallax setting (AO) are listed in the specifications chart on the back page of the CenterPoint catalog or on the specifications page in the column marked parallax setting (yds).
What is Parallax?
ANSWER: Parallax occurs when viewing distant targets and the reticle appears to shift or move. Adjustable objectives or side focus adjustment knobs allow the shooter to correct for parallax by dialing in on the distance of the target.
Why do I need a red/green illuminated reticle?
ANSWER: Illumination is a great feature for scopes because it allows the shooter to have a clear, bright reticle in any light condition. Standard black reticles can get lost if you are in the brush or a dark wooded area. Illumination will give contrast to the background, making it easier to identify your target. Offering dual illumination gives the user two contrasting colors for various lighting conditions and backgrounds.
Navigate within the web site and click on one of the scopes with the illuminated reticle. There is an animation of the reticle changing from black to green to red in different light conditions.
Are these scopes just for airguns?
ANSWER: No. All CenterPoint scopes will withstand the recoil of the most powerful caliber rifles on the market. They have gone through significant torture testing, including being used on everything from a high powered Webley Patriot break barrel to a .416 Rigby Magnum Centerfire Rifle.
Which ring's to use with which scope?
ANSWER: When determining which rings to partner with your CenterPoint scope, there are a few different questions to ask:
- What type of base is used on your gun? There are several different types of bases, we supply rings for the two most standard. 3/8" dovetail, which is commonly used on airguns and .22's. This is a grooved receiver like you see on airguns. The other is a 5/8" weaver rail. Depending on which type of base is on your gun, this will naw down the choices.
- What is the diameter of your scope's tube? 30mm or 25mm(1")?
- What size is the objective lens? This is the last number in description, i.e. 3-9x40mm, has a 40mm objective and the 8-32x56mm has a 56mm objective. This will determine what size profile your rings need to beow, medium or high.
- Low Profile - Fits up to 42mm Objective
- Medium Profile - Fits up to 45mm Objective
- High Profile - Fits up to 56mm Objective
For example - if you have a CenterPoint 8-32x56mm (CP832AORG) and a weaver style base on your gun: the tube size for this scope is 30mm and the objective is 56mm. Therefore, you would need CenterPoint Weaver Rings - 30mm, High Profile (CPM2PW-30H).
What is the purpose of the recoil pin on the rear ring? What do I do with it when mounting the scope?
ANSWER: All CenterPoint Dovetail ring mounts feature a removable recoil pin sited underneath the rear ring. Use supplied hex wrench to adjust the pin and slot it in to the recess of certain air rifle models to prevent the mount moving rearward under heavy recoil. Screw in such that the top of the screw is flush with the dovetail surface. Line the recoil pin up with the rear hole on the tube. For rifles that do not have this recess, simply remove the top half of the ring and unscrew the recoil pin to remove it.
Is the reticle first focal plane or second focal plane?
ANSWER: For scopes with reticle on first focal plane, the reticle will be proportionally changed when you change the power setting (the higher the power, the thicker the reticle). For scopes with reticle on second focal plane, the reticle will stay the same size/proportion no matter which power setting. All current CenterPoint scopes are made with the reticle on the second focal plane.
If the reticle is second focal plane, what magnification is the mil-dot reticle calibrated for?
ANSWER: Scopes with the highest magnification greater than 10x will be calibrated at 10x. For scopes with the highest magnification less than 10x, it is calibrated at the highest power. For example a 3-9x40mm would be calibrated at 9x and 8-32x56mm would be calibrated at 10x. It is recommended that you set the power at 10x, or the highest magnification setting for scopes less than 10x, when you use the scope for range estimating purposes.
On the Quick Aim Sights (red/green dot sights), what is the size of the dot at 100yards?
ANSWER: 7.5 MOA (Minute of Angle) or 7.5" at 100yds.
What is MOA? What does it mean if my scopes windage and elevation adjustment is 1/4 MOA?
ANSWER: MOA stands for Minute of Angle - a term used to designate variances on a target at 100 yards, most commonly used to describe the adjustment on a scope. If your scope's adjustment is 1/4 MOA, then for every click of the adjustment knob, the bullet's point of impact will move 1/4" at 100yds.
What is the best way to keep my scope lenses clean?
What maintenance is required on a riflescope?
ANSWER: None. With proper care and mounting, your scope will not need any maintenance. No lubricants or solvents are required to preserve mechanical function.
I have misplaced one of the Allen tools needed to adjust my scope, what should I do?
