Daniel Defense M4A1 13.9-inch on an LMT Lower with Griffin HEDP Barrel

Built around a Daniel Defense M4A1 SOCOM upper and its RIS II rail, this carbine sits on an LMT lower and swaps in a mid-length 13.9-inch Griffin barrel. It is set up for both day and night work: a 1-6 LPVO with a piggyback T2 red dot, an IR laser and a SureFire scout light share the quad rail. A suppressor rides a Rearden mount up front, and a two-stage LaRue trigger and B5 SOPMOD-style stock round out the lower.
