Understanding the Colt M16A1 Stripped Lower Receiver
A stripped lower receiver is essentially the foundation of any AR-15 style rifle. It's the part that houses the trigger group, fire control components, and buffer tube assembly. The Colt M16A1 stripped lower receiver specifically differs from later models in its features and markings. These differences are what contribute to its collectible value and appeal to enthusiasts.
Key Features and Identifying Characteristics:
- Rollmarkings: Authentic Colt M16A1 lowers possess distinct roll markings, including the Colt logo, "Colt's Mfg. Co." Hartford, Conn. U.S.A.," and the appropriate model designation. Careful examination of these markings is crucial for verifying authenticity. Be wary of counterfeits – poorly replicated markings are a telltale sign.
- Material: These lowers are typically manufactured from high-quality forged aluminum, providing durability and strength.
- Finish: While the original finish may vary depending on the production run, many collectors seek out receivers with their original parkerized finish.
- Serial Number: The serial number will provide clues to the receiver's age and origin. Researching the serial number can provide additional verification of authenticity and potentially uncover interesting historical context.
