Beretta OptimaChoke HP Features The OptimaChoke HP is machined from high-strength steel and finished in a nickel-alloy coating providing reliable corrosion resistance and surface durability through seasons of regular hunting and range use in a 20 gauge platform. Improved cylinder constriction opens the pattern quickly for close-range shooting situations making it an ideal choice for flushing upland birds skeet and any application where targets are engaged at shorter distances. The .75 extended length sits clear of the muzzle for a positive grip and effortless choke changes without reaching for a wrench. Optima-Choke HP threading provides a precise repeatable fit across the full range of compatible Beretta shotguns including the A400 Xtreme A400 Xplor A400 Xcel 690 692 DT11 A300 Xtrema and SV10. Interchangeability across all Optima-Choke HP threaded 20 gauge barrels means the OptimaChoke HP transitions between platforms without sacrificing fit or pattern consistency. Built to Beretta s competition-grade manufacturing standards this choke delivers reliable performance from the first shot of the season to the last.
