Briley Spectrum Browning Invector DS Extended Choke Tube

3706-IDSS12MO

Briley chokes are completely made in the USA, with tight tolerances, classic and modern designs, always with the shooter in mind. Spectrum chokes are an upgraded version of the standard extended choke with color coded bands for easy choke identification with a clean custom look. Each constriction is designated by the color of the band, and the band is also clearly laser marked for easy identification. The wrench slots are hidden within the colored spectrum band which also has a small radius at the top both enhancing the look and creating a snag free choke when sliding the gun into a slip. Extended chokes perform better than conventional flush chokes due to the additional length. Extended chokes have more length to gradually taper down from the bore of the barrel to the constriction of the choke causing less pellet deformation which produces a better pattern.

*Note on Invector DS Chokes: Browning factory chokes have a brass ring for a gas seal at the bottom of the choke, on Briley Replacements for Invector DS there is a ring machined directly in the steel of the choke’s body which performs the same sealing function. This may look a little different, but rest assured this is the correct choke.

Gun Models: Browning Invector DS - 12 and 20 gauge barrels in Citori 725 , New A5.

FAQ:
Question: Which choke system did my Browning come with?
Answer: Browning Invector DS original flush chokes are about 3-1/4" long with the threads at the top.

Question: Can I shoot non-toxic shot through my replacement chokes?
Answer: All Briley replacement chokes up to and including improved modified will handle steel, tungsten, etc. Briley replacement Helix, Plasma, and Titanium chokes are LEAD ONLY. Briley Thin Wall chokes must state FOR STEEL on the side of the choke. If not, then only lead or bismuth shot may be used.
