Drug cartel DIY open-bolt automatic rifles

Full article: Drug cartel DIY open-bolt automatic rifles

A development in improvised weaponry spearheaded by South America’s drug cartel armorers has been the blow-back operated open-bolt automatic rifle. The simple solution to the usual intricacies of a typical assault rifle’s locking, delay or gas operation is to essentially make a scaled-up submachine-gun with a very heavy bolt capable of operating at much higher pressures. Using a fixed firing pin and firing from the open-bolt position allows for relatively simple construction with minimal components. Police helicopters are rumored to be some of the intended targets.

The signature offset position of this example’s trigger and general receiver layout signal that it was probably based somewhat on the P.A Luty vol.II machine pistol design. Additions include a longer round receiver fitted with end caps, a STEN bolt turned down in diameter, a STEN type magazine well copy welded in place and an M16 type pistol grip.

 

A very crude example seized more recently which appears incomplete.
