Images have been circulating on Twitter of a Russian Spetsnaz soldier apparently testing out a PKM heavy machine gun with an unusual ammunition-feeding backpack that bears an uncanny resemblance to Jesse Ventura's alien-perforating minigun from Predator. The backpack, known as the Scorpio, is a product of Front Tactical Systems — and according to The Firearm Blog, it was designed at the request of the Russian military as a method of increasing machine gun efficiency.
Sometimes a controlled burst from a light machine gun just doesn’t cut it, which is why weapons manuals include detailed breakdowns on when a barrel change is recommended — like, say, after you fire 850 rounds from an M249 Squad Automatic Weapon in under a minute.
Last week, the U.S. Marine Corps released a Request for Information to manufacturers enquiring about their capacity to produce 11,000 more M27 Infantry Automatic Rifles. This stoked rumors that the Marine Corps is looking to replace its M4s with the M27, which were first sparked last November when 3rd Battalion, 5th Marines was equipped with the M27 instead of the M4 during pre-deployment exercises as an experiment.
