Upon receiving the two 16 gauge Zastava shotguns, I have decided that these guns are probably a great candidate for conversion. In addition to what seems like three areas of locking, the front lump near the forend has a protrusion that drops into a square cutout in the action. This makes 4 areas of locking. Is this an Anson and Deely action?
For those interested, Century Arms has these used shotguns for sale in 12 and 16 gauge for $100-$150.00US. These nice European guns already are equipded with sling swivels and one of mine even has a nice stock with a cheekpiece. It's almost like it was made to be converted to a DR.
