The light brown or tan color of High Reliability Combat Grease (HRCG) and High Reliability Lubrication Armor (HRLA), in contrast to the dark grey or black appearance of many traditional gun greases, results from their base thickener chemistry and the deliberate omission of messy solid additives:
- Natural Color of the Calcium Sulfonate Matrix:
Both HRCG and HRLA are built on a Calcium Sulfonate Complex thickener matrix. In its pure, un-dyed form, calcium sulfonate complex grease naturally has a smooth, beige-tan or light brown appearance. - No Molybdenum Disulfide (MoS2) or Graphite Fillers:
Traditional greases that appear dark grey or black usually contain heavy solid particulate fillers like molybdenum disulfide (MoS2) or graphite. Ronin’s Grips intentionally excludes these dark solid fillers because they leave messy black stains on hands and clothing, create a gritty residue in tight clearances, and can cause cosmetic staining on firearm finishes. - Inherent Extreme-Pressure (EP) Protection:
Instead of using black moly or graphite powder for heavy loads, HRCG and HRLA derive their extreme-pressure protection directly from the calcite crystalline structure of the calcium sulfonate thickener. This allows both products to achieve a massive load-carrying capacity (for example, a 620 kgf / 1,367 lbf Four-Ball EP Weld Load) while remaining clean and light-colored. - Cleaner Application and Inspection:
The natural beige-tan color is unobtrusive on dark firearm finishes. It allows shooters to easily see exactly where the lubricant has been applied and makes it simple to spot dirty carbon buildup during routine maintenance.
In short, the color is intentional given how we wanted the grease to perform.
