The Carlson Cremator Ported Choke 12 ga. Browning Invector DS MR, LR 2 pk. delivers advanced performance with Carlsons new Triple Shot Technology (TST), featuring three graduated rings in the taper to create a smoother transition from bore to constriction for tighter, more dense patterns. This design reduces pellet deformation and minimizes flyers, making the Cremator Series exceptionally effective on waterfowl throughout the season. With no size or speed restrictions when using steel shot in any of the three constrictions, these chokes also offer the benefits of an extended tube, including a 25% longer parallel section for tighter, more consistent patterns, along with wrench-less installation, quick removal, and muzzle protection. Available in ported or non-ported configurations, the Cremator tubes are precision-machined from heat-treated 17-4 stainless steel in the United States and carry Carlsons lifetime warranty. They are designed for Browning Invector DS MR 12 gauge barrels and provide reliable, all-season performance, combining versatility, durability, and improved shot pattern density for waterfowl hunters seeking consistent results across varied ranges.
