Determining the manufacturing year of a Colt AR-15 rifle can be a fascinating pursuit for collectors and enthusiasts. While Colt's serial number system isn't publicly documented in its entirety, piecing together information from various sources allows for a reasonable estimation. This guide focuses on identifying Colt AR-15 rifles with serial numbers beginning with "MH," a prefix associated with a specific period of Colt's production.
Understanding Colt's Serial Numbering System
Colt's serial number system is complex and has evolved over the years. It's not a simple linear progression where a higher number directly equates to a later manufacturing date. Factors such as production line, model variations, and even internal record-keeping practices influence the serial number structure. Therefore, pinpointing the exact year based solely on the serial number is often difficult and requires research.
The Significance of the "MH" Prefix
The "MH" prefix in a Colt AR-15 serial number generally indicates rifles produced during a specific period. While precise year ranges associated with specific prefixes are hard to definitively confirm without internal Colt documentation, anecdotal evidence and collector databases suggest a timeframe for "MH" prefixes. It's crucial to note this timeframe is an approximation based on observed patterns and may not be completely accurate for every single serial number. Further research using online forums and collector communities dedicated to Colt firearms can provide more specific information.
Methods for Estimating the Manufacturing Year
Beyond the prefix, other factors can help refine the year estimate:
-
Further Serial Number Digits: The digits following the "MH" prefix likely contain information that helps narrow down the production timeframe. The more digits you have, the more precise your estimate can be. However, the exact encoding scheme for these digits remains largely undocumented.
-
Colt Markings and Features: Carefully examine the rifle for other markings, such as the manufacturer's markings, model designation, and any other unique identifiers. These details can cross-reference with known production information and help date your specific firearm.
-
Online Forums and Databases: Dedicated Colt AR-15 forums and online databases maintained by collectors are invaluable resources. Posting images of your rifle’s markings and serial number can often help obtain assistance from experienced enthusiasts who may have encountered similar serial numbers. Remember to share only the necessary information for identification and avoid revealing potentially sensitive details.
-
Professional Appraisal: For high-value or historically significant Colt AR-15s, consider consulting with a professional firearms appraiser. Appraisers possess specialized knowledge and access to resources that may allow for more precise dating.
Disclaimer: Approximation, Not Precision
It's crucial to understand that any dating attempt based solely on partial serial numbers and publicly available information is an approximation. This information is for guidance and educational purposes only and should not be considered definitive proof of the manufacturing year. Always handle firearms safely and responsibly.
This guide provides a framework for understanding Colt AR-15 serial numbers with the "MH" prefix, but remember that dedicated research and community engagement are essential for a more accurate determination of the manufacturing year. Combining the information presented here with additional research through available resources will provide the most reliable estimation.
