If I understand correctly, you can insert these into your 12 gauge barrels to covert it to other gauges.
Has anyone tried them? If so, do they work?
If I have a Beretta 686 12 gauge and wanted to shoot 20 gauge every once in a while, is this a reasonable alternative to buying a whole different gun?
