.410 bore Rizzini chokes. Flush-fit tubes for the .410, in seven constrictions from Cylinder through to Extra Full — the tightest tube we make, and the one to reach for on turkey or any tight pattern work at distance.
Nominal bore is .410″ (10.4 mm). Also catalogued as 36 gauge, so tubes may be stamped either way.
Firearm content is age-restricted, we are required to ensure you are 18 or above.
