What Is a Rimfire Scope? The Difference You Need to Know

Q: What Is Parallax In A Rimfire Scope?

Parallax is an apparent shift between the reticle and target when the shooter's eye moves relative to the scope's optical axis. Rimfire scopes are often configured with a closer parallax setting, commonly around 50 or 60 yards, to suit typical rimfire shooting distances.

Q: Can I Use A Centerfire Scope On A Rimfire Rifle?

Yes, a centerfire-rated scope can generally be used on a rimfire rifle if the mounting system is compatible. However, its parallax setting, magnification range, size, and weight may not be optimized for typical rimfire distances. A dedicated rimfire scope may provide a more suitable setup.

Q: What Size Scope Do I Need For A .22 Rifle?

A 2-7x or 3-9x scope with an objective lens around 32mm is a versatile choice for many .22 rifles. The ideal magnification and objective size depend on the intended shooting distance, available light, rifle configuration, and personal preference.

Q: Are Rimfire Scopes Durable?

Quality rimfire scopes are generally durable enough for the relatively light recoil and typical conditions associated with rimfire rifles. Features such as waterproofing, fogproofing, and shock-resistant construction can improve durability, especially for outdoor use.

A rimfire scope is a type of rifle scope designed specifically for rimfire rifles. These rifles use rimfire ammunition, which is smaller and less powerful than centerfire rounds. Rimfire scopes are built to match the lower recoil and shorter shooting distances typical of rimfire firearms. They often offer lower magnification, lighter construction, and parallax settings optimized for closer ranges compared to scopes made for larger rifles.

Key Features Of A Rimfire Scope

Rimfire scopes have unique qualities that set them apart from other rifle scopes. Here’s what makes them special:

Lower Magnification: Most rimfire scopes range from 2x to 9x magnification. This is ideal for targets at 25 to 100 yards, which is common for rimfire shooting.
Parallax Adjustment: Many rimfire scopes have parallax settings fixed at 50 or 60 yards. This helps the shooter see a clear image at the shorter distances rimfire rifles are used for.
Lightweight Build: Because rimfire rifles are lighter and have less recoil, rimfire scopes don’t need heavy construction or strong recoil resistance.
Simple Reticles: Rimfire scopes often feature basic duplex or crosshair reticles, making them easy to use for beginners and hobbyists.

How Rimfire Scopes Differ From Centerfire Scopes?

Many shooters wonder if they can use any scope on any rifle. While it’s possible, rimfire scopes work best for rimfire rifles due to these differences:

Feature	Rimfire Scope	Centerfire Scope
Magnification	2x–9x	3x–20x (or higher)
Parallax Setting	Fixed at 50–60 yards	Fixed at 100 yards or adjustable
Weight	Lighter	Heavier (to handle more recoil)
Reticle Type	Simple (duplex, crosshair)	Complex (BDC, mil-dot, illuminated)
Price	Usually lower	Can be expensive

A common mistake is using a centerfire scope on a rimfire rifle. While it works, the parallax won’t be correct for close targets, and the scope will be heavier than needed.

Choosing The Right Rimfire Scope

Selecting the best rimfire scope depends on your needs and how you use your rifle. Here are some important things to consider:

Magnification Range: For target shooting or plinking, a 3-9x scope is usually enough. For small game hunting, 2-7x works well.
Objective Lens Size: A 32mm lens offers enough light for most daylight shooting. Bigger lenses add weight and aren’t needed for rimfire distances.
Parallax Setting: Make sure the scope is set for 50 or 60 yards. This gives a sharp view at typical rimfire distances.
Reticle Simplicity: Basic crosshairs or duplex reticles are easier for fast aiming. Fancy reticles are not needed for most rimfire use.
Durability: While rimfire rifles have light recoil, choose scopes that are fog-proof and waterproof for reliability outdoors.
Mount Compatibility: Rimfire rifles often use 3/8-inch dovetail rails. Confirm the rings fit your rifle.
Budget: Rimfire scopes are available from $40 to $200. More expensive models may offer better glass, but basic models perform well for casual use.

Practical Uses For Rimfire Scopes

Rimfire rifles and scopes are popular for several activities:

Plinking: Casual shooting at cans or paper targets. A rimfire scope makes this fun and easy, even for beginners.
Target Shooting: Many competitions for .22 LR rifles use rimfire scopes. Lower magnification and parallax settings help accuracy at 25 to 100 yards.
Small Game Hunting: Squirrels, rabbits, and other small animals are common rimfire targets. A good scope helps you aim precisely without extra weight.
Training New Shooters: Rimfire rifles are perfect for teaching marksmanship. The simple reticles and clear view of rimfire scopes help new shooters gain confidence.

Common Mistakes When Using A Rimfire Scope

Over-magnification: High power scopes can make finding targets harder at short distances.
Ignoring Parallax: Using a scope with a 100-yard parallax setting on a rimfire rifle leads to blurry images and less accuracy.
Wrong Mounts: Using mounts that don’t fit your rifle’s rail causes shifting and poor zero.
Unnecessary Features: Paying for illuminated reticles or bullet drop compensators is usually a waste for rimfire shooting.
Forgetting Eye Relief: Rimfire scopes can have shorter eye relief. Make sure you can see the full view comfortably.

Comparing Popular Rimfire Scopes

Here’s a quick comparison of three popular rimfire scopes:

Model	Magnification	Objective Lens	Parallax Setting	Weight	Price (approx.)
Bushnell Banner 3-9×40	3-9x	40mm	50 yards	12 oz	$70
Vortex Crossfire II 2-7×32	2-7x	32mm	50 yards	14 oz	$130
Simmons 22 Mag 3-9×32	3-9x	32mm	50 yards	10 oz	$50

Notice how each scope has moderate magnification, a 32mm lens, and parallax set for 50 yards. These features match the needs of rimfire shooters.

Non-obvious Insights For Beginners

Many new shooters focus on high magnification, thinking it will make them more accurate. In rimfire shooting, too much magnification can show every small movement, making it harder to aim. Also, a lighter, simpler scope helps keep your rifle balanced, which is important for offhand shooting.

Another detail often missed is the importance of mounting height. A scope that sits too high above the bore can make it hard to get a good cheek weld, reducing accuracy. Choose the lowest rings that clear the barrel and action.

When To Upgrade Your Rimfire Scope?

You don’t need to spend a lot to get reliable performance. However, if you shoot in low light or want finer adjustments, consider scopes with better glass and turrets. For competitions, look for scopes with adjustable objectives for extra precision.

A good rimfire scope can last for years. Invest time in learning to use your scope well, and it will serve you across many shooting sessions.

Frequently Asked Questions

What Is Parallax In A Rimfire Scope?

Parallax is a focusing problem that happens when the target and the reticle are not on the same plane. Rimfire scopes set parallax at 50 or 60 yards, keeping the image sharp at common shooting distances.

Can I Use A Centerfire Scope On A Rimfire Rifle?

You can, but it’s not ideal. Centerfire scopes are heavier and often set for longer distances, which can reduce accuracy with a rimfire rifle.

What Size Scope Do I Need For A .22 Rifle?

A 2-7x or 3-9x scope with a 32mm lens is perfect for most. 22 rifles. This combination gives clear views and easy handling.

Are Rimfire Scopes Durable?

Most rimfire scopes are built to handle light recoil and normal use. Look for waterproof and fog-proof models for added durability.

Last Word
