The Browning Invector-DS chokes fit flush with the end of your barrel but they are longer than other choke tubes. The DS Double Seal is a proprietary differential banded gas seal to eliminate residue build up. This makes the chokes easier to remove and install.
They have an integrated spring suspension that holds the seal tight but it still allows expansion against the barrel wall. This gives the Invector-DS a perfect fit and a smooth transition for the shot column as it enters the choke. This choke will fit Invector DS specific models only and it is not interchangeable with normal Invector Standard or Invector Plus choke systems.
