M16A1 Complete Upper Assembly
The M16A1 Complete Upper Assembly is the next iteration of DBI's popular AR15 Complete Uppers. Dirty Bird Industries has sourced some of the finest AR15 parts in the industry to ensure that this complete upper is not only a great throwback build and aesthetically accurate but also performs flawlessly in the field by taking advantage of modern enhancements to the platform.
Notable enhancements include a 1:9 twist instead of 1:12, which will stabilize a greater variety of bullet weights, M4 style feed ramps for improved reliability, and a black class 3 type 2 anodizing to match most modern mil-spec lower receivers.
