The new Browning Invector-DS system is the biggest
leap forward in choke tube design since interchangeable choke tubes
were introduced. Utilizing the proven thin wall configuration along
with a muzzle thread concept, Browning has taken shot pattern
performance to the next level. Add a brass alloy band at the base of
the tube, which seals out gas and grit that migrate between the barrel
and tube, and you have the most revolutionary choke tube on the planet.
Features include:
Longer overall length
Flush mount 3 ¼”
Extended 4”
Longer parallel surfaces
Proprietary brass seal
Thin wall construction reduces the flare at the muzzle end of the barrel for a sleeker appearance.
