VZ58 Build Tutorial 2
After removing the barrel, remove the rear sight. Use a small punch to depress
the sight spring and slide it out. Then remove the piston stop, it is the little
crescent shaped part in the bottom of the photo on the right. This needs to be
installed in the new receiver before the barrel is pressed in.

First we will prep the barrel by permanently installing the muzzle break / barrel
extension. I opted to silver braze it on with silver brazing paste it is a neat and

The parts must be clean and free from oil or grease, I gave them a quick
blast to clean them up and remove the paint from the sight base. The
paste is applied at the front of the threads and the muzzle device screwed
on. All excess was removed with a Q tip, this makes clean up easier.

The area to be brazed is heated evenly with a torch to a dull cherry red,
until the braze flowed evenly around the joint. Liquid metal flows towards
the heat source, so it is important to apply heat evenly to get a good bond.

The piston stop needs to be fitted to the receiver by grinding the upper
