A Zoom Blue Snap Caps are an easy and affordable option for dry fire training or just testing the functionality of your rifle. The incentive to using snap caps is that they protect the internal components of the firearm, mainly the firing pin, and A Zoom snap caps can withstand thousands of strikes. That's because they are designed with durability in mind. Each round is CNC-machined from a solid piece of aluminum and then receives a hard anodized finish. The result is smooth cycling and a long resistance to the wear and tear of being jammed into magazines and sprung out of ejection ports. A-Zoom offers Snap Caps in popular training, hunting, and duty calibers like .223 snap caps and .308 snap caps. Make A-Zoom Rifle Snap Caps part of your shooting training or gun maintenance needs.
