A 16" AR-15 barrel in a government / M4 contour, chambered in 5.56 NATO with a 1:7 twist and a mid-length gas system. The mid-length gas port sits farther forward than a carbine-length setup, which gives the bolt more dwell time and produces a noticeably softer, more consistent recoil impulse on a 16" build — the reason mid-length has become the default for most modern 5.56 rifles in this length.
Specs and features:
Build notes: plan on a mid-length gas tube and a handguard long enough to clear the mid-length gas block. Pair with a standard AR-15 M16-cut BCG, mil-spec charging handle, and low-profile gas block for a straight-forward 16" carbine build.
