Beretta Optima-Choke HP Flush Choke Tube Features The Beretta Optima-Choke HP Flush Choke Tube is built for shooters who need a dependable full constriction pattern out of a 20 gauge Beretta shotgun. The full constriction tightens the shot pattern for longer range work making it a strong choice for pass shooting waterfowl or reaching out on sporting clays stations that call for a denser more controlled spread. Because it is machined specifically for the Optima-Choke HP thread pattern it threads in with a precise consistent fit that keeps point of impact and pattern density repeatable shot after shot. The high strength steel construction holds up to the pressures of repeated use without the thread wear that can develop in softer tube materials. The nickel alloy coating adds a layer of corrosion resistance that matters in the field where mud moisture and powder residue are a daily reality and it keeps the tube turning freely for easy removal and cleaning. Its flush profile sits even with the muzzle so there is no protruding choke to catch brush gun cases or a shooting bag strap while in the field. Because it is fully interchangeable across every Beretta barrel threaded for Optima-Choke HP a single tube can move between an A400 Xtreme in the duck blind and a 692 on the clays course. For 20 gauge Beretta owners who want a factory matched upgrade over a modified or improved cylinder tube this full choke is a straightforward way to extend effective range.
