The Light Support Weapon or LSW is a light machine gun, of similar statistics to the SA-80 (given that 80% of the parts are interchangeable). The only difference between these two weapons is that the LSW has a heavier barrel, bipod, and a second handgrip. The range of the weapon is about 800 yards, and it fires a 5.56 NATO round for those who can't be bothered to check out SA-80 :-)
