Product DescriptionBuilt for serious waterfowlers, Carlson's Delta Waterfowl Extended Choke Tubes are machined from durable 17-4 stainless steel to deliver tighter, more consistent patterns than standard factory chokes. Each tube features a 25% longer parallel section to stabilize shot for denser downrange performance, with knurled ends for quick changes in the blind. Constriction and size are laser-marked on the end and body for easy identification. Safe for use with steel shot within recommended limits, the set includes Mid-Range and Long-Range options to match changing conditions.Product HighlightsPrecision 17-4 stainless steel construction for strength and corrosion resistanceExtended design with 25% longer parallel section for consistent, dense patternsKnurled ends and laser-marked constrictions for fast, easy identification and removalOptimized Mid-Range (MR) and Long-Range (LR) choke pair for versatile waterfowl setupsSteel-shot compatible; follow LR speed/size guidelines for best resultsSpecsCompatibility: Beretta/Benelli Mobil 12 GaugeChoke Types Included: Mid-Range (MR) and Long-Range (LR)Material: 17-4 stainless steel; extended profileNotable Features: 25% longer parallel section, knurled ends, laser-marked constrictionsSteel Shot Guidance: Do not shoot steel shot larger than BB or faster than 1550 FPS through the Long-Range choke; faster/larger loads should use the Mid-Range chokePackage Dimensions: 1.30 x 5.10 x 9.00 in (approx.)UPC: 723189071103MPN: 07110Brand: CarlsonsDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
