Carlson's Choke Tubes 56613 Replacement 56613 12 Gauge Improved Cylinder Flush 17-4 Stainless Steel

The Carlson's Choke Tubes 56613 is a 12 gauge improved cylinder flush choke tube built for Beretta and Benelli Mobil shotguns. If you run a Beretta or Benelli with Mobil choke threads and want a direct replacement that handles everything from upland birds to waterfowl, this is your go-to option. The improved cylinder constriction strikes a balance between shot spread and velocity, making it versatile for both hunting and clay shooting where you're working moderate distances.

These choke tubes are forged from 17-4 heat-treated stainless steel, a premium material that resists corrosion and holds up to repeated cycling and cleaning. The flush-mount design sits seamlessly with your barrel, keeping your sight picture clean and your gun's profile streamlined. You can run steel shot, lead, and Hevi-Shot through this choke without worry—just stay within sensible limits for velocities and pellet sizes, which we cover below.

Carlson's backs these tubes with a lifetime warranty and manufactures them right here in the USA, so you're getting American quality without the guesswork. Whether you're replacing a worn choke, building out a rotation for different hunting scenarios, or just want a solid stainless option that won't corrode after a season in the field, this is a no-fuss upgrade.
