The Zastava ZPAP92 is a robust 10-inch AK pistol chambered in 7.62x39mm, featuring a chrome-lined barrel, a large night brake, and a quad rail system for accessory mounting. It includes unique features like a hinged dust cover for optics, a last-round bolt hold-open, and a bolt-lock safety mechanism, offering a distinct Serbian AK feel and solid build quality.
This guide details the installation of a bolt-lock safety, a common police retrofit on German inter-war submachine guns like the Erma EMP. The process involves a three-screw housing and requires precise slotting in both the receiver and the bolt to allow a lever to lock the bolt in the forward, safe position. This modification enhanced safety for police carrying loaded weapons.
This entry details the Bang Model B1 self-loading rifle, a 1930s Danish design by Søren Hansen Bang. Expert Jonathan Ferguson of the Royal Armouries highlights its innovative short-stroke gas piston system and unique bolt lock safety.
