BudsGunShop.com - What commercial style chokes can be used?

It interchanges with the berretta/benneli mobil choke.
The 12-gauge models feature an 18″ barrel with removable chokes, including an extended cylinder bore choke brake that helps tame recoil with heavy shot or slugs. Standard Full and Improved Cylinder chokes are also included, with other options from HatsanUSA. Each gun ships with two 5-round magazines and a 2-round magazine that can be stored in the buttstock. The gun is chambered to accept 2 ¾” and 3″ shells and will cycle them interchangeably with no external adjustments required by the shooter.
