HM Defense’s Defender M5 rifle features a HM MonoBloc 4150 chromoly, match grade barrel with an integral machined gas block and is tripled honed and button rifled. The Defender M5 utilizes a 15″ free-float 1913 Picatinny rail and is compatible with Magpul M-Lok mounting system. To finish off this tactical firearm is a Mil-Spec HM stock and enhanced grip.
The HM Defense Guardian M5L features a patented MONOBLOC barrel with integral gas block which eliminates any chance of gas block misalignment or gas leakage. Constructed from 4150 chromoly, HM Defense barrels are tripled honed and button rifled for superior accuracy. The Guardian M5L uses forged 7075-T6 Mil-Spec upper and lower receivers with a Type III hard coat anodized finish.
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.
