The HM Defense 16MBUP-556 features a patented Monobloc upper with an integrated gas block barrel. The 4150 Chromoly barrel is 16" in length with a 1:8" twist and mid-length gas system. The 16MBUP-556 includes a 10-3/8" free-float M-LOK handguard.

HM Defense rifles include an M16 bolt carrier group with a patented HMB bolt. The HMB bolt eliminates the common pass through cam hole found on most bolts. The HMB's design eliminates this weak point by using a partial hole with added material. Additional benefits include elimination of the cam pin hole staking, reduction in cam & firing pin contact and smoother operation of the BCG. The HMB is compatible with Mil-Spec M16 bolt carriers.
