Carlson's Choke Tubes 38030 TSS Turkey 38030 Invector Stevens 301 410 Gauge Turkey 1.5" Flush Steel

The Carlson's TSS Turkey choke tube for Invector Stevens 301 .410 gauge delivers the tight, consistent patterns serious turkey hunters demand from a flush-mounted choke. Designed to work seamlessly with Federal Premium Heavyweight TSS turkey loads—and compatible with other manufacturers' smaller shot sizes (7–9)—this steel choke tube harnesses the density advantage of tungsten super shot to pack more pellets downrange than traditional lead. If you're pushing the effective range of a .410, this tube is built for that mission.

Tungsten super shot's 22% density advantage over heavyweight shot and 56% advantage over lead means more energy retention at distance and tighter, denser patterns in the critical 10-inch circle at 40 yards. That matters on wary, long-range turkeys. The choke works with any ammunition using the FliteControl Flex wad, so you're not locked into a single load—you can experiment and dial in what your gun likes.

At 1.5 inches long, this flush design seats cleanly in your Stevens 301 without protruding, keeping the profile sleek and interference-free in brush or tight blinds. Steel construction and Invector-pattern threading make installation and removal straightforward. If you're running a .410 dedicated to turkeys and want to stack odds in your favor downrange, this is the choke tube to trust.
