Our Take

This is the kit that actually lists its calibers, and it’s a long list: .17, .22/.223/5.56, .243, .280, .30, .357/9mm, .40, .45, and 12-gauge. That covers everything from a .17 HMR varmint rifle to a 12-gauge shotgun — genuinely universal. At approx. 250 g it’s mid-weight, so expect a solid rod and a real brush spread. The honest math: covering nine calibers plus 12-gauge means some brushes are doing double duty, and .17 brushes are fragile by nature. If you’re a one-or-two-caliber shooter this is overkill; for a household safe with a bit of everything, it’s the right single kit to own.
