Evolve Weapons Systems 14.5″ 5.56 Midlength Barrel, EWS Taper

This barrel from EWS is their latest addition to line up, intended for duty and hard-use rifles. Button-rifled from 4150 CMV and chrome-lined for longevity.

These barrels feature an improved profile from EWS that is a constant taper from the barrel extension to the gas block journal. This helps place material near the chamber where you need it most for both heat dissipation and rigidity.

Finished in a mag phosphate exterior and chrome-lined interior. Dimpled for use with low-profile gas blocks. Intentionally made to be compatible with use for front sight bases and ‘A’ frame-style front sight gas blocks. Gassed for use with and without a suppressor.
