The Carlson’s Modified Choke Tube (brand part no. 51203) is a 20-gauge choke cut to the Remington (Rem Choke) thread pattern. It carries a Modified constriction, a middle-of-the-road constriction for general-purpose patterning.

Key Specifications

• Cut to the Remington (Rem Choke) thread pattern.
• Sized for 20-gauge shotguns.
• Carries a Modified constriction — a middle-of-the-road constriction for general-purpose patterning.
• Machined from stainless steel for corrosion resistance.
• Uses a flush-mount profile, threading in flush with the muzzle and leaving no tube visible past the barrel, unlike an extended choke.
• Interchangeable with other 20-gauge Remington-threaded shotguns.
• Installs as a direct swap for the factory-installed choke in this thread pattern.
• Ships at approximately 0.085 lb, light enough to carry a spare in a range bag.

Frequently Asked Questions

What does a Modified constriction do? It’s a middle-of-the-road constriction for general-purpose patterning, one of several constrictions Carlson’s offers so you can match the choke to the range and shot you’re shooting.

What shotguns does this choke fit? It’s cut to the Remington (Rem Choke) thread pattern, so it drops into 20-gauge shotguns built around that choke system.

Is this a flush or extended choke? It’s a flush-mount choke, sitting inside the barrel with no extension past the muzzle.
