This Remington manufactured late variation 23" long (24" overall) barrel is for the late model 514 bolt action rimfire rifle with the thinner barrel channel as this barrel measures .625" wide just ahead of the receiver and .625" at the muzzle. This thinner late variation barrel is in very good condition retaining the majority of its original blue finish with a some specks of older rust and light wear. The bore is bright and rates excellent.  (file photos)
