ACSM
Originally known as BCWS, ACSM is a modded R15 and R6 version of the ACS 2.0 gun engine. ACSM offers a unique third person feature with tons of other features added on to the ACS engine to enhance your MILSIM experience. ACSM includes BCWS 2.0 which is a rewritten and redone version of ACS based on the former BCWS system, with a much more realistic and comprehensive extension of the ACSM engine.
