Black Rifle Balm is engineered for semi-auto rifles and centerfire pistols. Provides 10x longer reliability than gun oils and flawless cycling under heat.
Bolt Balm is meant for manual actions found in bolt guns, lever-actions, revolvers, and others, whose moving parts generally operate under slower speeds but often under higher loads. It's especially effective in easing the forces necessary in cocking bolts, and smoothing out sticky actions.
