Our Assessment: This AR-15 SOPMOD Block II rifle is built on a Aero M4E1 lower receiver fitted with a Geiselle two-stage trigger, an LMT pistol grip and an LMT SOPMOD stock with battery storage, giving the platform a blend of match-ready control and mission-ready ergonomics. The two-stage trigger provides a predictable pull for precise follow-ups while the LMT furniture provides a solid and comfortable interface to the rifle.
The upper is a COLT receiver mated to a Colt chrome-lined 14.5″ 1:7 twist barrel terminated with a pinned-and-welded four-prong SureFire flash hider that also functions as a suppressor host for SureFire cans. A Daniel Defense quad rail forend (factory designed to clear an A2-style gas block) gives ample accessory mounting real estate, and the rifle is fitted with a TangoDown vertical foregrip. The complete upper assembly was built by Charlies Custom Clones, a known builder of high-quality clone rifles, resulting in a SOPMOD Block II that pairs authentic period parts with a modern trigger and furniture upgrades for serious field and range use.
