Our Sporting Clays Choke Tubes are crafted from durable 17-4 stainless steel and precision-machined to deliver superior patterning performance compared to standard Choke Tubes. Featuring a 25% larger parallel section, these chokes produce consistent, tighter patterns, ensuring accuracy on the course. Knurled ends allow for easy, tool-free removal, with laser-marked constriction details for quick identification. These versatile Choke Tubes are compatible with a variety of shot types, including lead, steel, copper-plated, nickel, Hevi-Shotshells and Buckshot. However, avoid steel shot larger than BB in any choke tighter than Full Constriction. Designed to fit Ruger Long Style Chokes (post-1993 12 Gauge systems), these Choke Tubes provide denser patterns than flush-mount chokes and they're backed by a lifetime warranty for lasting reliability.
