Carlson's Rifled Choke Tube for 20 Gauge Invector Shotguns

A rifled choke tube for 20 gauge Invector shotguns transforms your smooth-bore shotgun into a more accurate platform for slugs and other rifled projectiles. Carlson's Rifled Choke Tube is engineered from 304 stainless steel and features a right-hand rifle twist (1:35) with a .620-inch groove diameter designed specifically for 20 gauge Invector-compatible shotguns. Whether you're hunting with a Winchester, Browning, or Mossberg platform that accepts Invector chokes, this tube delivers the spin and support your slugs need for tighter, more predictable groups downrange.

The matte black finish resists glare and corrosion in the field, while the precision rifling imparts consistent rotation to your projectiles. Depending on your specific shotgun model, the tube protrudes between .625 and 1.3 inches from the barrel, so fit varies by platform—verify compatibility with your firearm before purchase. This is the right choice if you're stepping up from standard smooth-bore patterns to serious slug hunting or accuracy work on the range.

Installation is straightforward on any shotgun equipped with Invector choke tube threads. The stainless construction handles repeated use and harsh weather without degradation, making it a durable addition to any 20 gauge hunting or sport shooting setup.

Frequently Asked Questions

What shotguns does this rifled choke tube fit?

This choke tube is designed for 20 gauge shotguns with Invector choke threads, including Winchester, Browning, and Mossberg 500 models equipped with Invector-compatible systems. Verify your shotgun's choke system before purchase, as some newer Winchester models (SX-2, SX-3, SX-4, SXP) use Invector Plus tubes, which differ from standard Invector.

Will a rifled choke tube improve my slug accuracy?

Yes. The right-hand rifle twist and precision rifling impart rotation to rifled slugs and projectiles, which stabilizes them in flight and can significantly tighten your group sizes compared to a smooth-bore pattern.

What's the difference between this and a standard choke tube?

A standard choke tube is smooth inside and is designed for shot patterns. A rifled choke tube has spiral grooves that spin projectiles, making it purpose-built for slug hunting and precision accuracy work rather than bird or clay shooting.

How much does this tube protrude from the barrel?

Protrusion ranges from .625 to 1.3 inches depending on which type of shotgun it's installed in. Check your shotgun's specific specifications or manual for the exact measurement on your model.
