The Carlson's Flush Mount Skeet Choke Tube for Beretta/Benelli Mobil 20ga .615 is crafted from 17-4 heat treated stainless steel to deliver durable, corrosion-resistant performance on Beretta and Benelli Mobil shotguns. This flush-mounted design provides a clean fit and consistent choke alignment, making it a trusted choice for skeet shooting, where tight, reliable patterns at mid-range targets are essential. The choke is designed to accommodate a variety of loads, including steel, lead, and Hevi-Shot, with the practical caveats noted for constrictions tighter than full: avoid steel shot larger than BB or speeds exceeding 1550 fps in tighter-than-full configurations, and in the Turkey constriction, steel shot larger than #4 is not permitted. These guidelines help shooters maximize pattern efficiency while protecting the choke from excessive wear. With its .615 constriction, the flush mount keeps the muzzle streamlined for quick target acquisition and balanced handling, whether you're dialing in targets at the skeet range or working with varied upland loads. Carlsons reputation for precision-machined choke tubes ensures consistent performance, durability, and reliable patterning shot after shot.
