Carlsons Choke Tube Flush - Mount 20ga Full Tru-choke

The Carlsons Choke Tube Flush-Mount 20ga Full Tru-Choke is a precision-engineered shotgun choke designed for shooters who demand reliability and consistent patterns in 20-gauge shotgun systems. Purpose-built for hunters, sport shooters, and tactical operators, this flush-mount choke eliminates exterior protrusion, reducing snag hazards and maintaining a streamlined profile critical in law enforcement and defensive shotgun applications. The full choke constriction delivers tight shot grouping ideal for extended-range shooting where pattern density directly impacts target acquisition and hit probability.

Manufactured from 17-4 stainless steel, the Carlsons choke features a 25% larger parallel section that enhances shot cup support and pattern consistency—a critical advancement for competitive and professional shooters. The .705-inch diameter specification is optimized for 20-gauge bore geometry, and the Tru-Choke design delivers superior uniformity across varying ammunition loads. The improved modified constriction bridges the gap between full and modified patterns, offering versatility without sacrificing performance. Stainless steel construction provides extended service life and resistance to corrosion, essential for firearms subjected to harsh field conditions or frequent cleaning protocols.

Law enforcement shotgun teams and tactical operators benefit most from the flush-mount design, which integrates seamlessly into furniture setups without interfering with breaching equipment or securing mechanisms. Hunters pursuing upland game and waterfowl at distance will appreciate the tighter patterns for ethical, clean kills at extended range. Installation is straightforward—simply remove the existing choke and hand-thread the Carlsons tube until snug. Critical note: this choke is rated for lead and bismuth shot only and is not compatible with steel shot, a restriction that applies to most premium chokes due to material hardness considerations. Verify 20-gauge compatibility with your specific shotgun model before purchase.
