The Browning Invector DS 12 Gauge Extended Choke Tube in Light Modified delivers a nickel chrome moly construction designed to extend beyond the barrel end for straightforward removal and consistently tighter shot patterns. The proprietary differential banded gas seal prevents residue accumulation while facilitating effortless choke changes. An integrated spring suspension maintains the seal’s integrity while permitting expansion against the barrel wall to achieve a seamless fit and smooth shot column transition into the choke. Gas control occurs at the interface between the choke and its seating point in the bore.
Specifications include 12 gauge chambering with Light Modified constriction, stainless steel construction, and Invector DS thread pattern compatibility. The tube measures 1.20 x 5.10 x 8.45 inches. Extended design positions the choke beyond the barrel muzzle, with knurled ends ensuring a secure grip during installation and removal. A brass alloy band seal maintains tight contact to eliminate residue buildup. From skeet to full choke, patterns tighten consistently and reliably across the Browning Invector DS lineup.
