Beretta USA JCTUBE21 MobilChoke20 Gauge Full Flush Steel Silver
The Beretta USA JCTUBE21 MobilChoke 20 gauge full flush choke tube is a factory replacement or spare choke option for Beretta shotguns chambered in 20 gauge. If your Beretta 20 uses the flush-mount choke system, this full constriction tube delivers the tighter shot pattern you need for longer-range hunting or more predictable clay shooting. Flush chokes sit nearly level with the barrel muzzle, keeping your gun trim and making barrel swaps quick and hassle-free.
The MobilChoke system is Beretta's proven quick-change platform, so installation and removal take seconds without tools. Steel construction holds up to regular field use and cleaning. A full choke is at the tighter end of the constriction spectrum, best suited to hunters and shooters pursuing ducks, geese, or long-range upland birds—anywhere you want pellets clustered tight downrange. If you shoot clay games, a full can also help tighten your pattern for longer house shots.
Keep a few spares on hand so you're never caught without the right constriction for the day's hunt or match. Beretta choke tubes are straightforward to swap between outings, making it easy to tune your 20 gauge to changing conditions.
