Description
Bring authentic Vietnam-era styling to your next build with the Retro M16A1 HYDRAMATIC Lower Receiver. Precision-machined from a solid billet of 7075-T6 aluminum, this lower replicates the exact profile of the original M16A1, making it ideal for retro, clone, and reproduction rifle projects. Unlike modern forged receivers with incorrect “A2” contours, this lower features the proper front takedown lug geometry and receiver extension profile for true historical accuracy.
Each lower undergoes over 3 hours of detailed machining time to capture the curved profiling of the classic M16A1. Finished in a Colt-style lighter gray, this receiver is ready for your choice of standard AR-15 or M16-pattern components. The finish is slightly lighter than older Colt gray tones, but with a little carbon in the anodizing and natural wear from oily fingers after shooting, it darkens beautifully and develops a stellar, authentic look.
