The Carlson choke tube flush mount is a Remington-compatible, stainless steel replacement designed for 20 gauge shotguns, crafted from 17-4 heat-treated stainless steel for lasting durability and reliability. This flush-mount choke features a .595 diameter and is configured with the Rem Choke thread pattern, offering an Improved Modified constriction that helps balance pellet dispersion and target engagement at typical upland and waterfowl ranges. It may be used with lead shot on any constriction, providing versatility across a variety of field conditions, while recommending care not to use steel shot larger than #BB in a choke tighter than full to prevent excessive wear and potential damage. The flush design maintains a low-profile fit within the muzzle, promoting clean handling and consistent point of aim, and its stainless construction resists corrosion from field use and damp environments. Ideal for hunters seeking a reliable, corrosion-resistant upgrade or replacement, this Carlson choke tube enables precise performance with compatible Remington chokes, delivering improved pattern density and dependable performance across common 20 gauge hunting scenarios, from birds in flight to closer retrieves.
