Colt and Diemaco also paired up to develop a [[squad automatic weapon]] variant of the series. The Diemaco Light Support Weapon (LSW) features an enlarged straight [[Gas-operated reloading|gas tube]] and an almost 1 inch thick heavy barrel to make the barrel less susceptible for [[Thermal shock|overheating]] and hence increase the [[Rate of fire#Effective rate|sustained or effective rate of fire]] capability. The LSW can only fire automatically and uses a proprietary Diemaco hydraulic buffer assembly. The LSW has a boxy square handguard with a carrying handle and a vertical foregrip that can be used as a [[monopod]].

The LSW was made with no [[bayonet lug]] until 2001<ref>{{cite web|url=https://sadefensejournal.com/the-colt-lmg|title=The Colt LMG|last=Bartocci|first=Christopher R.|date=2022-09-19|publisher=Small Arms Defense Journal|access-date=1 July 2024}}</ref> due to the original [[bipod]]. A new bipod attaches to the same barrel yoke as the carrying handle and front grip, so current LSWs are made with a bayonet lug. Unlike many M16 variants, it fires from an [[open bolt]], necessitating the removal of the [[forward assist]] for operating safety. It was the only weapon in the Diemaco product line to feature an M16A2-type fully adjustable rear sight, allowing the rear sight to be dialed in for specific range settings between 300 and 800 meters and to allow windage adjustments without the need of a tool or cartridge.

The LSW was used by the [[Royal Danish Army]] and is still used by the [[Netherlands Marine Corps]] (LOAW / LOAWNLD). It fires from a [[closed bolt]] and also has a semi-automatic firing mode and forward assist. The Diemaco LSW was originally a license produced variant of the Colt 750, but both Colt and Diemaco have upgraded their respective weapons to include features like a detachable carry handle.
