The Beretta TX4 breaching choke tube is a 6 point design, configured for tactical duty. Made from light weight 6061 military-spec aircraft aluminum, this unit was designed for its radical look. However, it's still a fully-functional muzzle brake/recoil reducer. Don't let the looks fool you though, this device is still a fully functional breacher for occasional use.
