Beretta A300 Outlander Sporting 12-3/30 J30TJ10 

In keeping with the Beretta tradition, the new A300 Outlander is a soft-shooting gas-operated system semi-auto which combines the reliable Beretta bolt with falling block (locked breech) with an improved gas valve with a self-cleaning cylinder and piston, so that excess pressure caused by the most powerful cartridges can be decreased automatically.
