A replaceable choke tube designed for 12-gauge shotguns, the Carlson Choke Tube in Moderate constriction fits Winchester, Mossberg 500, Browning Invector, Weatherby, and Savage platforms. Built from 17-4 heat-treated stainless steel, this tube handles steel shot, lead, and Hevi-Shot ammunition across standard hunting and sport-shooting loads. It's the kind of workhorse component that lets you dial in your shotgun's pattern for different games and distances without buying a new barrel.

If you run a Winchester, Browning Invector, Mossberg, Weatherby, or Savage 12-gauge, swapping choke tubes is one of the easiest ways to adapt your gun to whatever's in front of you—tighter patterns for distant ducks, more open spreads for close-cover birds. This moderate-constriction tube sits right in the middle of that range, making it a sensible all-rounder for hunters who want one dependable setup. The flush-mount design keeps the tube recessed in the barrel for a clean, snag-free profile.

Carlson's backs these tubes with a lifetime warranty, and every one is manufactured in the USA. That's the kind of durability and accountability you want when you're trusting a small part to perform under real hunting conditions.
