Product DescriptionCarlsons Ported Buckshot Choke Tube is engineered to deliver tight, consistent patterns with 00 and 000 buckshot from Remington shotguns that use the Rem Choke system. The extended, ported design reduces recoil and muzzle jump, while the precision constriction optimizes performance with a wide range of loads. Machined from durable 17-4 heat-treated stainless steel and finished in black, this 12-gauge choke extends about 1 inch beyond the barrel and is compatible with lead, steel, and Hevi-Shot loads. Note: Do not use with steel shot larger than BB or with steel shot exceeding 1550 FPS.Product HighlightsDesigned for Remington shotguns with the Rem Choke systemPorted and extended design helps reduce recoil and muzzle risePrecision constriction optimizes buckshot patterningDurable 17-4 heat-treated stainless steel with black finishCompatible with lead, steel, and Hevi-Shot loads; important steel-shot restrictions applySpecsGauge: 12 GaugeFit: Remington Rem ChokeChoke Type: BuckshotConstriction Diameter: .700 inchExtension: Approximately 1 inch beyond barrelPorted: YesMaterial: 17-4 heat-treated stainless steelFinish/Color: BlackLoad Compatibility: Lead, Steel, and Hevi-ShotRestrictions: Not for steel shot larger than BB or faster than 1550 FPSBrand Name: CarlsonsUPC: 723189133993Manufacturer Part Number: 13399Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
