The Carlson Delta Waterfowl Extended Choke Tubes for Beretta/Benelli Mobil LR 12ga are crafted from 1704 stainless steel to deliver tighter, denser patterns than conventional chokes, with a 25% longer parallel section that promotes more consistent pellet flight and improved long-range performance for waterfowl and upland hunting alike. Designed for quick field service, each choke tube features a knurled end for easy removal and a laser-marked constriction and size on both the end and body, allowing instant reference and confident tube selection in the field or on the range. These extended tubes are engineered to handle steel shot with exceptional results, expanding versatility across popular shotgun platforms without sacrificing durability. The black finish provides a rugged, corrosion-resistant profile that stands up to routine field use while maintaining smooth operation under demanding conditions. By combining a longer parallel portion with precise construction and clear markings, Carlsons Delta Waterfowl Extended Choke Tubes help you maximize pattern consistency, enhance flock-breaking performance, and achieve more consistent shotshell performance when hunting waterfowl or chasing high-density targets.
