Carlson's Brass Wool 20ga Shotgun Snap Caps 2/ct

These Brass Wool snap caps have a spring loaded primer plunger which prevents firing pin damage during dry-firing exercises. Treat the wool chamber mop with your favorite gun oil to prevent rusty chambers during storage. NOTE: leaving guns cocked during storage is hard on springs and is dangerous. These will help keep your shotgun in good condition. 2 per pack.
