While slower than modern twist rates, the 1:12 twist is well-suited for lighter bullet weights commonly used during the era when the XM177E2 was in service, providing authentic performance characteristics. Classic Black Finish The upper receiver and barrel are finished in a durable matte black coating that closely matches the appearance of original military-issue firearms. This finish provides good corrosion resistance while maintaining the classic, non-reflective look desired in retro builds.
