The SOCOMโs new lightweight machine gun to replace M240 SAW could be Sig Sauerโs SLMG, a brand new designed machine gun. The SLMG, the Sig Sauer Lightweight Machine Gun, was unveiled this week at the Shooting, Hunting and Outdoor Trade Show,ย the Army Times reports.
Since May 2017, the U.S. SOCOM (Special Operations Command) has been hunting for a new lightweight machine gun. Then they have revealed that they are looking for 5,000 belt-fed machine guns that, chambered in .338 Norma Magnum, weighed under 24 pounds.

Weighing in at 20 pounds and rocking a foldable stock, the SLMG seems to fit these conditions. A former member of Armyโs 3rd Special Forces Group and current Sig Sauer Academy instructor, Colin Murphy, claimed that the SLMG is โthe lightest, most powerful [man-portable] machine gun on the face of the earth,โย accordingย to Military.com.
The SIG SAUER Next Generation Squad Weapons system is the only submission entirely designed, engineered and manufactured by a single American company.
The SLMG rate is 600 rounds a minute, Military.com reports, which also meets SOCOMโs requirements. It also fulfills SOCOMโs requirement of having an effective range of 2,000 meters. Even better,ย Army Times reportsย that engineers at Sig Sauer are working on designing a โdrum-typeโ magazine that could be used as an alternative to belt-fed ammunition.
SOCOM also requires that the machine gun can use both suppressed and unsuppressed barrels. According to Sig Sauer, the SLMG isnโt just suppressor-ready, but tests havenโt revealed any change in the weaponโs rate of fire while using a suppressor, according to the Army Times.
Indeed, the SLMG could โnot only replace the M240 SAW in most tactical scenarios but also provide enough reach and firepower in the vehicle, boat and aircraft-mounted .50-caliber machine gun configurations,โ as Army Times reported.
However, it is worth noting that this is Sig Sauerโs first stab at a medium machine gun. When the contract was first announced in 2017, it seemed likely that SOCOM would end up with General Dynamicsโ 24-pound medium machine gun, given that, at the time, it was the only platform in production that can chamber the .338 Norma Magnum round.
The story is developing and further information is yet to be released, according to the various sources.
