.22 Magnum AR 15 Upper: The Ultimate Guide


When it comes to firearms, the AR-15 is one of the most popular rifles in America. It’s versatile, customizable and has been used by military personnel all over the world. But what if you wanted something a little different? Enter the .22 Magnum AR 15 Upper.

This unique upper receiver is designed to fit onto your existing lower and transform your rifle into a rimfire shooter. In this article, we’ll explore all things related to this conversion kit including comparisons with other uppers, benefits of owning one and tips for using it effectively.

What Is A .22 Magnum AR 15 Upper?

First off let’s define what exactly a .22 magnum is – also known as the WMR (Winchester Magnum Rimfire) cartridge. It's essentially a beefed-up version of its younger sibling – the standard .22 LR cartridge but packs more punch due to its wider bullet diameter and higher velocity.

Now that we have an understanding of what exactly we're dealing with here let's dive in further on topis related solely to ".22 magnum ar 15 upper".

The “Upper” part refers specifically to just that; it's only half of an entire firearm, which houses parts such as barrel assembly bolt carrier group receiver rails etc whereas "AR-15" refers specifically only lowers which are responsible for housing lower receiver assembly trigger guard grip magazine well etc.

Comparing With Other Uppers

One thing people often wonder when thinking about purchasing a new item like this upper is how does it compare? Let's see:

Standard Uppers

Compared with standard uppers (.223/5.56), there are several differences worth noting:

  1. Ammunition Cost: One significant advantage using .22 magnum cartridges over .223 or 5.56 NATO rounds would be cost savings.
  2. Recoil: As a rimfire cartridge, the .22 Magnum also offers considerably less recoil than standard uppers which makes it perfect for beginners or those seeking a more relaxed shooting experience.
  3. Distance Accuracy: Due to its smaller size, the effective range of .22 magnum is considered shorter (around 200 yards), but this still gives you plenty of leeway for target or small game hunting.

Other Rimfire Uppers

While there are other rimfire uppers available such as .17 HMR and .22 LR, these cartridges aren’t as powerful as .22 magnum. This essentially means that they have reduced stopping power especially when dealing with larger animals.

Benefits Of Owning A .22 Magnum AR-15 Upper

Some of the unique benefits you stand to gain from owning one include:

  1. Economic Value – Using lower priced ammunition compared to 5.56/.223 rounds can save you quite some cash.
  2. Effective Hunting – The high velocity and long-range accuracy make this upper ideal for small game hunting in addition to training purposes.
  3. Tactical Advantage- In tactical situations, having access to multiple caliber weapons gives an edge against your opponent.

Tips For Using Your New Conversion Kit Effectively

Using your new kit requires preparation and proper handling techniques:

  1. Always check your ammo before loading any firearm; ensure that it matches specifications designated by manufacturer guidelines.
  2. Ensure compatibility between your upper receiver and lower receiver before attaching them together using appropriate tools like torque wrenches etc..
  3. Clean thoroughly after every use because buildup of debris may cause jamming issues.


The .22 Magnum AR 15 Upper is an excellent addition to anyone looking for something different from their go-to firearms arsenal at a great value price point without sacrificing performance capabilities across basic target practice on through hunting needs!


What is a .22 Magnum AR 15 Upper and how does it work?

A .22 Magnum AR 15 Upper is a conversion kit that can be added to your existing AR-15 rifle, allowing it to fire the .22 WMR (Winchester Magnum Rimfire) cartridge. The upper receiver contains all necessary components, including barrel, bolt carrier group, and magazine.

The kit can be easily installed onto an existing lower receiver of your AR-15 rifle with minimal modifications required. It allows for greater versatility in shooting as the smaller caliber round offers less recoil which results in more accurate shooting at longer ranges.

One of the primary benefits of this conversion is that it offers significant cost savings over traditional ammunition such as a standard 5.56 NATO round while providing similar performance characteristics.

What are some notable features of a .22 Magnum AR 15 Upper?

One notable feature of these uppers is their lightweight construction which allows for ease-of-use during extended periods at the range or out hunting small game animals such as squirrels or rabbits.

Another feature worth mentioning about these uppers includes its compatibility with most standard parts from other manufacturers; this makes customization easy when you want to add your personal touch to your weapon system.

Finally, perhaps one of its most compelling features – these uppers allow for both indoor and outdoor use due to their reduced noise output when compared with larger calibers like 5.56 NATO rounds.

Can I use any type/brand/make/configuration/etc.. lower receiver with my new .22 magnum upper?

While many lower receivers on the market will work well alongside a new .22 magnum upper receiver- there are certain things you should keep in mind that could make matching components easier:

  1. Make sure they’re both compatible regarding size: not all lowers will fit perfectly onto every different kind or brand's top end.
  2. Check if there’s sufficient clearance between the uppers' and lowers' components.
  3. Ensure that both parts have enough space to accommodate one another.

It is recommended you do some research beforehand or consult with a professional prior to making any changes or upgrades, as compatibility issues may arise if not done correctly.

What kind of ammunition should I use in my .22 Magnum AR 15 Upper?

When it comes to selecting the right ammunition for your new .22 magnum upper receiver, there are many different brands and styles available on the market today- each offering their own unique benefits.

You'll want to choose ammo that provides high accuracy while remaining consistent across multiple rounds. Make sure you're using high-quality brass cased cartridges with good reviews from reputable sources like online forums or user groups.

Some of our top recommendations in this area include offerings from CCI Maxi Mag, Hornady V-Max, Federal Game-Shok Ultra Match – all of which offer excellent performance characteristics when used in conjunction with your new upper receivers.

How accurate is a .22 Magnum AR 15 Upper compared to other caliber rifles?

When discussing accuracy between different calibers such as those found on an AR-15 platform – It's important first understand that several factors come into play when determining how well a gun will perform at long ranges including wind speed/direction; atmospheric pressure; bullet weight/shape; barrel length/materials/etc..

That being said though- typically speaking: A properly tuned .22 magnum upper can be highly accurate out past one hundred yards unless shooting conditions are less than ideal (windy weather). Shooting position also plays an important role here as stability matters greatly when trying achieve maximum precision shots at distance.

Compared against larger calibers like 5.56 NATO rounds which experience more recoil during firing/reloading procedures due their heavier weight/bullet size – The smaller grain count and lighter caliber round means less kickback after each shot allowing for faster follow-up shots while still retaining accuracy over long distances.
