DIY Guns Captured After The Zamboanga Seige
Compact 40mm Grenade Pistol
A number of DIY guns were recovered by the Philippines army after the the rebel siege of the southern city of Zamboanga. They include 40mm grenade pistols, a gun vaguely patterned after an M4 and a Mac-10 clone.
While only bearing on a slight resemblance to the real thing, this does appear to have an AR-15-style buffer tube.
