The CMMG .22LR Conversion Kit Review

The CMMG .22LR Conversion Kit is designed to quickly convert a standard AR-15 rifle, originally chambered in 5.56 NATO or .223 Remington, to a .22LR caliber rifle. The kit typically includes a .22LR bolt carrier group (BCG) and a compatible magazine, making the conversion process straightforward:

  • Bolt Carrier Group (BCG): The conversion bolt is the heart of the kit and is designed to replace the standard 5.56/.223 BCG in the AR-15. It is built to mimic the dimensions and fit of the original BCG but is chambered for .22LR cartridges.

  • Magazines: The kit comes with one or more magazines designed to fit .22LR rounds but sized to accommodate the AR-15's magazine well.

The CMMG .22LR "Bravo" kit comes with a .22LR conversion bolt,and three magazines, all conveniently packaged together in an easy-to-open blister pack.

The CMMG .22LR "Bravo" kit comes with everything you need! Note: the bolt includes a handy black rubber protective cap for storage outside of the rifle.

Installation Process

Installing a CMMG .22LR Conversion Kit is remarkably simple and can be done in a few quick steps, making it accessible even to those who are not highly technical:

1. Remove the existing 5.56/.223 BCG: Clear your AR-15, ensuring it is safe and unloaded. Remove the existing bolt carrier group from your rifle.

To install the CMMG .22 conversion bolt, simply break open your AR15...

...and remove the .223/5.56 bolt carrier group (BCG).

2. Insert the .22LR Conversion Bolt: With the black rubber protective cap removed, slide the .22LR conversion bolt into place where the original BCG was located. Use your existing AR-15 charging handle. Cycle the bolt to ensure smooth operation and lubricate as necessary.

With the black rubber protective cap removed, fully insert the CMMG .22LR conversion bolt in place of your rifle's bolt carrier group, push it fully flush into the upper reciever...

...and close up your AR15. It's a good idea to work the bolt a couple of times to ensure everything is cycling smoothly. Apply lubrication as required.

3. Load the .22LR Magazine: Insert the provided .22LR magazine loaded with .22LR ammunition.

The CMMG .22LR conversion kit's magazines fit into the standard AR15 magazine well as the stock magazines do, but will only load .22LR ammunition.

4. Ready to Fire: Your AR-15 is now ready to shoot .22LR rounds.

This quick and easy installation process allows shooters to switch calibers with minimal downtime, making it perfect for extended training sessions or plinking.

Benefits of Using the CMMG .22LR Conversion Kit

  • Cost-Effective Training: .22LR ammunition is significantly cheaper than 5.56/.223 rounds, allowing for more extensive training sessions at a lower cost.

  • Reduced Recoil: The .22LR round offers substantially less recoil, which is ideal for new shooters and those sensitive to the heavier kick of larger calibers.

  • Maintain Rifle Familiarity: Shooters can train with the same rifle platform they are accustomed to. This maintains the feel and handling of the AR-15, ensuring skills are directly transferable.

Considerations and Limitations

While the CMMG .22LR Conversion Kit offers numerous advantages, there are some considerations to keep in mind:

  • Accuracy and Range: While adequate for training and recreational shooting, the .22LR is a shorter range cartridge and may not provide the same accuracy as a dedicated .22LR rifle, particularly at longer ranges.

  • Cleaning: The .22LR ammunition tends to be dirtier, and the blowback operation of the conversion kit can leave more residue in the rifle. Regular cleaning is necessary to maintain optimal function.

  • Compatibility: Ensure that your AR-15 is compatible with the conversion kit, especially in terms of gas system and barrel configuration.

Conclusion

CMMG .22LR Conversion Kits for AR-15 rifles are an excellent tool for those looking to enhance their shooting experience without breaking the bank on ammunition costs. It provides a practical training solution while maintaining the familiar ergonomics and operation of the AR-15 platform.

Whether you're a seasoned shooter looking to reduce costs and recoil or a new shooter aiming to practice with ease, this conversion kit is a valuable addition to your shooting repertoire.

Remember, while it converts your AR-15 for .22LR Ammunition use, it is important to switch back to the original BCG for defensive or tactical use with standard calibers.
