Browning Extended Invector DS 12GA Choke Tube

This Browning Extended Invector DS choke tube is engineered for 12-gauge shotguns and offers an Improved Modified constriction. Constructed from nickel chrome moly stainless steel, the tube extends beyond the barrel end for convenient removal and delivers tighter shot patterns. The proprietary differential banded gas seal prevents residue accumulation and simplifies installation and removal. An integrated spring suspension maintains the seal’s tension while permitting expansion against the barrel wall to ensure a proper fit and smooth shot column transition into the choke. Gas flow is managed at the interface where the choke seats in the bore. Whether you’re shooting skeet or full choke applications, patterns tighten consistently and reliably. The tube measures 1.25 X 4.90 X 8.20 inches and uses the Invector DS thread pattern. Features include a knurled end grip for secure handling, a brass alloy band seal that prevents residue buildup, and a length that exceeds competitor offerings. This tube cannot be shipped directly to California.
