Product Description

These Invector DS Choke Tubes will only fit guns stamped on barrel Invector DS. They are much longer than other Browning choke tubes and have threads on the muzzle end of the tube.  They are the most innovative choke system to hit the market. Unique Double Seal design features a brass alloy ring around the base of the tube to effectively seal the area between the tube and the barrel wall against gas and residue that make the tube difficult to remove.
