The Browning Invector DS 12 Gauge Extended Full Choke Tube delivers a Full choke constriction in an extended configuration that projects beyond the barrel end for straightforward removal and consistently tighter shot patterns. This stainless steel choke tube features Browning’s proprietary differential banded gas seal, which prevents residue accumulation while facilitating effortless installation and removal. An integrated spring suspension maintains the seal under tension and permits controlled expansion against the barrel wall, creating a seamless transition for shot entering the choke. Gas dynamics are managed at the critical interface between choke and bore seating point.
Specifications: 12 gauge, Full constriction, Invector DS thread pattern, extended (not flush) design, stainless steel construction. Dimensions: 1.20 × 4.70 × 8.70 inches. The tube extends longer than competitor offerings and features knurled ends for secure grip, plus a brass alloy band seal that eliminates residue buildup. From skeet to full choke, patterns tighten consistently and reliably.
