I was asked by a customer to make a muzzle adapter for the M92 ZPAP AK pistol and figured I would oblige!
adapter threads onto the unique Yugo M92 ZPAP in 26x1.5mm LH to allow
the use of a more standard 5/8-24 UN threading to be used.
out of 17-4 stainless and black nitride coated, these adapters take out
the slop in the AK barrel by indexing on the muzzle face, not the front
sight base. Tighten up this bad boy with a wrench onto your barrel and
you'll get a great alignment. Please do check with a rod to ensure
concentricity before sending it though! The blem is merely a non-centered wrench flat.
