Finding the right bolt for your AR-15 or AR-10 platform can feel overwhelming, given the variety of options available. This comprehensive guide will break down the key factors to consider when selecting a .22LR bolt for your AR, ensuring you make an informed decision. We’ll cover everything from compatibility and features to performance and maintenance.
Understanding .22LR Conversion Bolts for AR Platforms
A .22LR conversion bolt allows you to shoot inexpensive .22 Long Rifle ammunition in your AR-15 or AR-10 platform. This is advantageous for cost-effective training, plinking, and small-game hunting. However, it’s crucial to understand that these bolts are not direct replacements for the standard 5.56/.223 or other calibers. They are purpose-built to handle the significantly lower pressures of .22LR cartridges.
Key Factors to Consider When Choosing a .22LR Bolt
Several factors influence the performance and reliability of a .22LR conversion bolt. These include:
1. Compatibility:
- AR-15 vs. AR-10: Ensure the bolt is explicitly designed for either the AR-15 (most common) or AR-10 platform. Mixing and matching is a recipe for malfunction and potential damage.
- Manufacturer Specifications: Always check the manufacturer's specifications to confirm compatibility with your specific upper receiver and lower receiver. Some bolts may have restrictions based on the type of buffer system or other components.
2. Bolt Material and Construction:
- Steel vs. Other Materials: Most .22LR conversion bolts are made from steel, offering good durability and reliability. Some may use other materials, so check the specifications for the specific bolt you’re considering.
- Finish: A quality finish (e.g., nitride or other protective coatings) helps resist corrosion and wear, improving the bolt’s longevity.
3. Firing Pin and Extractor:
- Firing Pin Strength: The firing pin's strength and design are critical for reliable ignition. Look for a bolt with a robust firing pin.
- Extractor Design: The extractor is responsible for pulling the spent casing from the chamber. A well-designed extractor is essential for smooth operation and preventing malfunctions.
4. Reliability and Performance:
- Functioning with Different Ammunition: A reliable bolt should function smoothly with a variety of .22LR ammunition types. However, always test your chosen ammunition to ensure consistent performance.
- Feeding and Extraction Reliability: A high-quality bolt will demonstrate consistent feeding and extraction, minimizing malfunctions like jams or failures to extract.
5. Ease of Installation and Maintenance:
- Simple Installation: Look for a bolt that is relatively easy to install and remove. The process should be straightforward, without requiring specialized tools or extensive gunsmithing knowledge.
- Cleaning and Lubrication: Regular cleaning and lubrication are crucial for maintaining the reliability of any firearm component. A bolt with easily accessible parts for cleaning will enhance its long-term performance.

The market offers several reputable manufacturers of .22LR conversion bolts. Research and read reviews to find one that aligns with your needs and budget. It’s crucial to remember that every firearm is unique, and what works well for one person might not be optimal for another.
Safety Precautions
- Always follow safe gun handling practices.
- Never dry fire your AR with a .22LR conversion bolt.
- Use only .22LR ammunition in a .22LR conversion bolt.
- Regularly inspect your bolt and clean your firearm.
Choosing the right .22LR conversion bolt is vital for a satisfying and safe shooting experience. By carefully considering the factors outlined above and prioritizing quality and compatibility, you can enhance the versatility and affordability of your AR platform. Remember to consult your firearm's manual and seek advice from experienced gunsmiths or shooters if you have any doubts or concerns.
