Machined from brass for a durable and long lasting finish, snap caps allow you to dry fire a shotgun without causing any damage to the firing pins. The sprung centre allows the firing pin to rebound upon striking as it would with a real cartridge, enabling you to practice dry firing in your home, relieving the pressure on leaf sprung firing pins and much more.
 
You can re tighten the springs inside with the use of an Allen key making these snap caps last much longer than the plastic type.
