What is a .22 Conversion Kit for AR-15?
Definition
The AR-15 rifle. It’s a cornerstone of the American firearms landscape, a platform embraced by enthusiasts for its modularity, customization options, and inherent adaptability. Whether you’re a seasoned shooter or just starting out, the AR-15’s popularity is undeniable. However, one of the primary drawbacks associated with enjoying this versatile platform is the cost of ammunition. The price of .223/5.56 rounds can quickly add up, limiting range time and the opportunity to hone your skills. This is where a solution steps in: the .22 conversion kit.
This article delves into the world of .22 conversion kits for AR-15s, exploring their benefits, types, and essential considerations. By understanding these kits, you can unlock a more cost-effective way to practice, train, and enjoy your AR-15. The .22 conversion kit offers a practical path to extended range sessions, improved shooting proficiency, and pure shooting enjoyment, all while preserving the familiar handling and feel of your primary firearm.
Explanation
At its core, a .22 conversion kit is a clever modification designed to adapt your existing AR-15 rifle to fire .22 Long Rifle (LR) ammunition. Essentially, the kit replaces parts of your existing bolt carrier group, enabling the AR-15 to chamber, fire, and extract .22 LR rounds. These kits usually include a modified bolt carrier group and/or a .22 LR-specific magazine.
The conversion process is typically straightforward. You remove your standard bolt carrier group from your AR-15’s upper receiver and replace it with the .22 conversion kit’s bolt carrier group. The .22 conversion bolt carrier group is designed to accommodate the smaller .22 LR cartridge. You’ll also often swap in a dedicated .22 LR magazine designed to feed the rimfire rounds reliably.
Unlike a dedicated .22 AR-15 rifle, which has a completely separate upper receiver and bolt, the conversion kit utilizes the existing lower receiver and barrel of your AR-15. This is a key advantage, preserving the familiar ergonomics and control of your AR-15 while drastically reducing the cost per shot. The modularity of the AR-15 platform makes this conversion process relatively easy and reversible, allowing you to switch between centerfire and rimfire capabilities quickly.
Advantages of Using a .22 Conversion Kit
Money Savings
The most immediately apparent advantage is the significant reduction in ammunition costs. .22 LR ammunition is significantly cheaper than .223/5.56. The price difference is substantial, allowing you to purchase far more rounds for the same amount of money. This increased accessibility to practice ammunition translates directly into more range time and more opportunities to hone your skills. The more you shoot, the better you become. This cost-effectiveness makes the .22 conversion kit a smart investment for any AR-15 owner looking to maximize their time at the range without breaking the bank.
Practice and Development
Beyond the financial benefits, a .22 conversion kit opens doors to enhanced training opportunities. The .22 LR round replicates the feel of shooting a centerfire rifle but with minimal recoil and noise. This low recoil enables shooters to concentrate on fundamental techniques like trigger control, sight alignment, and breathing without the distractions of a heavy-recoiling round. You can perform the same drills you’d use with your .223/5.56 AR-15, focusing on the basics with a cost-effective ammunition.
Fun Shooting and Recreation
The joy of shooting .22 LR is undeniable. Whether you’re plinking at targets, introducing new shooters to the sport, or simply enjoying a leisurely day at the range, .22 LR is a blast. The low noise and minimal recoil make it perfect for casual shooting and can be especially enjoyable for introducing new shooters or families to the world of firearms. The conversion kit allows you to transform your AR-15 into a fun and approachable recreational firearm.
Recoil Reduction
The near-absence of recoil is another advantage. This allows for faster follow-up shots and reduces the fatigue associated with prolonged shooting sessions. This is particularly beneficial for new shooters, who may find the recoil of a .223/5.56 round intimidating. The conversion kit provides a stepping stone to more powerful calibers, increasing comfort, allowing for greater confidence, and improving marksmanship skills.
Stealthy Training
Depending on your local regulations, shooting full-power .223/5.56 rounds may have restrictions on where they are allowed. However, .22 LR might be permitted in areas where centerfire rounds are not. The .22 conversion kit therefore offers a way to maintain your skills even when access to a full-fledged range or shooting area is limited. This allows for convenient and continuous skill development.
Available Kit Styles
Bolt Carrier Group Conversions
The most common type of .22 conversion kit is the bolt carrier group (BCG) conversion. These kits consist primarily of a replacement bolt carrier group (sometimes including a magazine). The replacement bolt is modified to accommodate the .22 LR round, featuring a firing pin designed to strike the rimfire cartridge’s rim. These kits are generally easy to install. You simply remove your existing AR-15 bolt carrier group and replace it with the .22 conversion kit’s bolt carrier group. Many manufacturers create conversion kits that readily install into your existing lower.
Consideration of the Magazine
Many .22 conversion kits include their own proprietary magazines. The magazines often are made to ensure the .22 LR cartridges are fed reliably. You may have to use these magazines because the conversion kit will not interface with standard AR-15 magazines. Consider the magazines’ capacity and reliability. Some conversion kits might work with adapters or modified versions of standard AR-15 magazines, but it’s important to ensure proper feeding.
Various Brands and Models
Several reputable manufacturers offer .22 conversion kits for AR-15s. Brands such as CMMG and Spikes Tactical, are well known and are respected for their quality and reliability. They typically offer a complete conversion kit that will give you a drop-in and ready to use system. Researching the brands and comparing reviews will help you find the right option. When browsing, it is useful to compare the build quality, the included features, and the prices.
Important Considerations Before Purchasing a Conversion Kit
Match to the Rifle’s Build
The first and most important consideration is compatibility. Ensure the conversion kit is compatible with your AR-15’s upper receiver. Most kits are designed to work with standard AR-15 uppers, but it’s always wise to verify compatibility, especially if you have a non-standard configuration. Also, be mindful of the barrel twist rate. .22 LR cartridges typically perform best with specific twist rates. Confirm that your barrel’s twist rate is suitable for .22 LR ammunition.
Reliability Factor
Reliability is paramount. Conversion kits can sometimes be sensitive to different types of .22 LR ammunition. Experiment with a few different brands and types of .22 LR ammunition to find what performs best in your setup. Be prepared to troubleshoot potential issues such as failures to feed, failures to extract, or failures to fire. Some minor adjustments might be necessary to achieve optimal reliability.
Accuracy Expectations
Understand the potential differences in accuracy between a .22 conversion and your .223/5.56 AR-15. While conversion kits can be accurate, they may not always replicate the precision of a dedicated centerfire rifle. The accuracy can be impacted by the conversion kit’s bolt, the barrel’s twist rate, and the ammo. Manage your expectations. The value of the .22 conversion kit is primarily in its cost-effectiveness and practice utility.
Maintenance and Cleaning
The .22 conversion kit requires regular cleaning. .22 LR ammunition can leave behind more fouling than centerfire rounds. Clean the kit after each shooting session to maintain its functionality. Follow the manufacturer’s recommendations for cleaning, using appropriate bore cleaners and solvents. Proper cleaning ensures reliable performance and extends the life of the kit.
Cost Considerations
The price of .22 conversion kits varies depending on the brand, features, and included accessories. Set a budget. Compare different options, and read reviews to find the best value for your needs. Consider the long-term savings on ammunition costs when making your decision.
Installation and Use
The installation of a .22 conversion kit is generally straightforward, but it’s crucial to follow the manufacturer’s instructions carefully.
Begin by ensuring your AR-15 is unloaded. Remove the magazine and verify the chamber is empty.
Remove the existing bolt carrier group from your upper receiver.
Insert the .22 conversion kit’s bolt carrier group.
Insert the .22 LR magazine.
Follow all safety precautions. Always treat the firearm as if it is loaded.

For optimal results, experiment with different types of .22 LR ammunition to determine which performs best in your rifle. Always clean your .22 conversion kit after each shooting session, and adhere to the manufacturer’s cleaning instructions.
Troubleshooting Common Difficulties
Troubleshooting Feeding Issues
Failures to feed (FTF) can result if the .22 LR cartridges are not properly aligned with the chamber. Check that your magazine is securely inserted and that the magazine follower is functioning correctly. Ensure your ammunition is in good condition and clean. Sometimes the bolt itself can experience issues. If the bolt does not seem to be functioning smoothly, it is important to make adjustments to the kit. Try a different brand of ammunition.
Addressing Extraction Problems
Failures to extract (FTE) can happen when the spent casing is not fully removed from the chamber. This can be caused by a dirty chamber, weak extractor, or insufficient gas pressure. Clean the chamber thoroughly, and check the extractor for any damage. Try different brands of ammunition. A little bit of gun oil may help, but use with caution.
Correcting Issues of Failure to Fire
Failures to fire (FTF) sometimes result from light primer strikes. This can be caused by a weak firing pin spring or a dirty firing pin channel. Clean the firing pin channel thoroughly, and consider replacing the firing pin spring. Try a different brand of ammunition as well.
Tackling Accuracy Issues
Inaccuracy may arise from various factors, including ammunition type and barrel conditions. Try different brands and types of ammunition to see if accuracy improves. Ensure your barrel is clean. Use a quality bore cleaner and follow the manufacturer’s instructions.
