Pachmayr snap caps are designed for safe, repeated dry firing and function testing without causing damage to the firearm. Molded from resilient polymer, these snap caps are built for durability and long service life. Each 24-pack provides ample supply for extended training or maintenance use. Extensive testing has demonstrated that these polymer snap caps can endure up to five times more hammer drops compared to typical disposable rimfire snap caps, making them a reliable and cost-effective choice for rimfire firearm owners. Ideal for preserving firing pin integrity during dry fire practice.
