The LSAT rifle, of the LSAT (Lightweight Small Arms Technologies) program, is a developmental assault rifle. Design began in 2008, four years after the beginning of the LSAT program. Like the LSAT LMG, the rifle is designed to be significantly lighter than existing designs, and is designed to fire lighter ammunition. Like the rest of the program, the weapon extensively uses parallel development. It has designs for and caseless ammunition, and designs using spring-loading magazines and weapon-powered magazines. This parallel development reduces the risk of the program failing. Computer simulation and modelling, particularly of the LMG, is being used for all components of the program, including the rifle. This reduces both time and expenditure for prototyping and testing. The other program
