It has several features conducive to its use as a light machine gun, such as a quick-change barrel, a vented handguard, a belt feeding mechanism, provisions for the use of an ammunition pouch, and a rate of fire of approximately 600 RPM. The LMG design is a traditionally laid-out machine-gun. ДЄ soldier engages a close range target with the light machine gun during a military unit assessment at Fort Benning, Ga. Cased telescoped ammunition weighs 40% less than brass-cased ammo, so a 100-round ammunition belt weighs about 2В lb for the LSAT, compared to 3.3В lb for a brass-cased belt. The standard LSAT machine gun weighs 9.4В lb empty, compared to 17.6В lb for a standard SAW. Secondary goals have also been met: the LMG has the potential to improve battlefield effectiveness (due to its simpler and more consistent weapon action, its light weight and low recoil, and its stiffer barrel) its use of recoil compensation (with a long-stroke gas-system, for example) has produced positive feedback regarding controllability the simpler mechanism of the LMG is both more reliable and easier to maintain a rounds counter has been integrated to improve maintainability, and the weapon is capable of accepting other electronic devices improved materials used in the chamber and barrel have reduced heat load on the weapon and the weapon cost is equivalent to the existing M249. The LMGs built made a 44% and 43% reduction of weight (for the cased telescoped and the caseless weapons, respectively). LSAT without magazine, mock fire for the first time by Picatinny Senior Commander and PEO Ammunition Brig. The parallel development of the two ammunition types meant that, if the caseless ammunition effort succeeded, much of the development work gained with the composite cased weapon could be applied to it, and, if it failed, the composite-cased version was likely to succeed on its own. The cohesive team of companies is combined with government support to ensure success.

A competition down-selected the design concepts of various companies to leave an AAI Corporation-led team of companies as the developers of the weapon system. The program also uses a 'spiral development' approach, whereby the weapon and ammunition is rolled out in stages or 'spirals', each stage producing a new version that is an improvement on those from previous spirals. For development, the use of extensive computer simulation and modelling reduces both time and expenditure for prototyping and testing. The use of advanced computer simulations to accelerate development may have mitigated this. Use of an LMG for this purpose is notable, considering its greater technical complexity than infantry rifles. Дevelopment began with the two types of weight-reducing ammunition, and a light machine gun to serve as a testbed and technology demonstrator. By May 2015, 85,000 cased-telescoped rounds had been fired through 10 test weapons, with testers claiming the weapon had gone as far as it can go until the Army decides if it wants to make it a program of record. After further research and development into both technologies and the guns that fire them, one of the two variants was to be chosen for production. As of 2008, it had two configurations, one that fires cased telescoped ammunition, and one that fires caseless ammunition. The LMG provides a major reduction in weight over legacy weapons, as well as improvements in other areas, such as controllability and reliability. The program was initiated in 2004, when the Joint Service Small Arms Program (JSSAP) challenged the American defence industry to develop a lighter small arms and also design lighter ammunition.

The purpose of the program was to develop a lighter, yet highly reliable light machine gun (LMG). The LSAT light machine gun is a component of the Lightweight Small Arms Technologies (LSAT) program.
