The Daniel Defense 10.3″ Government Profile Barrel is a cold hammer forged 5.56 NATO barrel built around a carbine-length gas system specifically suited to compact AR-15 configurations. Its 1:7 twist, chrome-lined bore and chamber, and heavy phosphate exterior provide the same duty-oriented construction found throughout Daniel Defense’s short-barreled 5.56 lineup. This version is sold as the standalone barrel, allowing the gas block, gas tube, and remaining upper components to be selected separately.
Note: Gas block, gas tube, barrel nut, and muzzle device are not included.
