The U.S. military has called upon the M240B belt-fed medium machine gun
for two decades to provide troop support with suppressive and direct
fire. These weapons have put millions of rounds downrange, and littered
the sand with hot empty brass, links and blood when called upon. The
M204B is reliable, but troops in the field alerted their higher ups that
improvements were needed. A request went out to "cut the fat" from a
weapon that incorporates design features that date back to the end of
WWI. Barrett Firearms, dependable provider of the M107 .50 semi-auto,
took the initiative and designed the M240LW (Light Weight) to take
advantage of cutting-edge manufacturing techniques. http://www.tactical-life.com/online/exclusives/barrett-next-gen-m240lw-sneak-...
