The Trulock choke tubes are an excellent product. All Trulock chokes are made from 17 4 ph grade stainless steel. This steel has an extremely high resistance to staining and rust. Trulock chokes are heat treated to a high strength level (200,000 PSI) in order to resist wear. They craft all of their chokes on CNC lathes from solid bar stock. Welded tubing is never used. All Trulock chokes carry a lifetime warranty.
