LMT Specwar 12.5-inch SBR with ACOG ECOS and HUXWRX Flow 556K

An LMT Specwar monolithic upper on a full-ambi MARS-L lower, running LMT's 12.5-inch mid-length barrel as a do-it-all general-purpose rifle. The builder pairs an LMT enhanced bolt with a Centurion Arms sand-cut carrier and keeps the gas untouched behind a low-back-pressure HUXWRX Flow 556K. A Trijicon TA31 ACOG with a piggyback RMR, a Cloud Defensive Rein 3.0, a LaRue MBT-2S and a VLTOR EMOD round it out after months of trying other optics and parts.
