Geniune, Factory Brand Extensions Increase Mag Tube Capacity
Dependable, factory made magazine extensions provide additional round capacity for tactical operations and competition. All-steel extension tubes attach directly to the end of the magazine tube to increase total capacity by as much as three rounds. Included magazine clamp attaches around the barrel and the extension for added support. Magazine spring is formed from high strength music wire that resists “set” and won’t weaken over time. Models available with 13/8" swivel loop and clamp-mounted swivel stud. Available with matte blue or Parkerized finish.
