20ga Mossberg 500 505 .570 Anaconda Choke Tube by PatternMaster

Product Description

The PatternMaster Anaconda Striker (.570) is a precision choke tube engineered for consistent, tight shot patterns and long-term durability. Designed for 20-gauge Mossberg 500 and 505 barrels, Model 5610 employs PatternMaster’s patented Coil Zone™ gas-over-constriction technology (US Patent #8,276,305) to deliver Full to Extra Full patterns with predictable density and range for patterning applications. Constructed from aircraft-quality 17-4 PH stainless steel and finished with a Military-Spec Chemical Agent Resistant Coating (CARC), the Anaconda Striker is built for reliable, repeatable performance and corrosion resistance.

Key Features & Benefits

  • Coil Zone™ gas-over-constriction design (US Patent #8,276,305) for consistent pattern density.

  • Optimized .570 bore diameter for predictable Full to Extra Full patterning results.

  • Extends effective patterning capability to distances commonly used in patterning tests (typical results up to 60 yards with recommended loads).

  • Aircraft-quality 17-4 PH stainless steel for strength, wear resistance, and longevity.

  • Military-Spec CARC powder coat finish for enhanced corrosion and chemical resistance.

  • Affordable, value-focused design for patterning and performance testing.

  • Direct fit for Mossberg 20-gauge 500 and 505 threaded choke barrels (confirm barrel threading before purchase).
