Beretta Optima-Choke HP Features The Beretta Optima HP Choke Tube is built in a cylinder constriction the most open choke setting producing the widest shot pattern for close-range shooting situations. Manufactured from high strength steel the tube is designed to handle repeated firing cycles without deforming or wearing prematurely. A nickel-alloy coating finishes the exterior and bore of the tube adding corrosion resistance that helps the choke hold up over years of use in the field. Its flush-fit design keeps the tube from protruding past the muzzle preserving a clean barrel profile. This choke tube threads into any Beretta barrel cut for the Optima-Choke HP system making it fully interchangeable across the A400 Xtreme A400 Xplor A400 Xcel 690 692 DT11 A300 Xtrema and SV10 shotguns. That broad compatibility lets a shooter who owns multiple Optima-Choke HP equipped Beretta shotguns share the same set of chokes between guns. Built specifically in 20 gauge this tube gives 20 gauge shooters the same flush interchangeable choke system available on larger gauge Beretta shotguns. For shooters wanting the widest possible pattern for close targets this Beretta Optima HP cylinder tube is a precise factory-matched choke option.
