Micro-ceramic protection.
A performance-focused additive package helps reduce friction where metal meets metal.
Jacob Grey x SpecMud
Built to run. Built to last.
A Jacob Grey private-label firearm lubricant built with fully synthetic base oils and micro-ceramic anti-friction technology. It stays on the job through extended shooting and helps keep carbon from becoming a cleanup problem.
Less carbon fight.
Helps reduce carbon adhesion and caking so post-range cleanup takes less time and effort.
Put it where it works.
Purpose-built applicators and two viscosities give you control from major bearing surfaces to tight internal parts.
Choose your formula
Two viscosities. Zero guesswork.
Use the heavier Grey formula where you want a durable, stay-put film. Reach for Lite Orange when you need controlled flow into smaller or tighter areas.
Grey / Higher viscosity / 2 oz
Hard-use. Stay-put.
The heavier-consistency formula for rails, barrel contact points, locking surfaces, and other high-load areas. Designed to maintain a protective lubrication film through extended shooting sessions.
Slide rails
Barrel contact
Hard use
Extended sessions
Lite Orange / Lower viscosity / 1 oz
Precision flow. Tight access.
A lower-viscosity formula with an optimized additive package for trigger groups, pins, small components, and tight internal areas. Also well suited for operation in extreme cold temperatures.
Trigger groups
Small parts
Tight areas
Cold weather
