Ronin’s Grips High Reliability Combat Grease (HRCG) — Product Overview

Heavy-Duty Calcium Sulfonate Impact Armor for High-Pressure Frame Rails, Locking Lugs, and Heavy Recoil Mechanisms

1. Why Heavy Recoil & High-Impact Rails Need HRCG

If you shoot heavy-recoiling handguns, bolt-action rifles, open-bolt machine guns, or firearms stored in humid coastal environments, liquid gun oils often wipe away under heavy impact. Every time a slide or bolt slams back and forth, liquid oil gets squeezed out from between the frame rails and locking lugs, leaving metal grinding directly against metal.

Ronin’s Grips High Reliability Combat Grease (HRCG) solves this problem with heavy-duty physical armor. Built on a premium Calcium Sulfonate Complex (CSC) thickener matrix and pure synthetic base fluids, HRCG stays right where you put it. It cushions heavy impact loads, clings to vertical rails under violent recoil G-forces, resists water wash-off, and protects your firearm from rust—even when exposed to harsh salt air.

2. Four Reasons Shooters Trust HRCG Combat Grease

  • Massive Extreme-Pressure Load Protection: HRCG carries an extraordinary Four-Ball EP Weld Load rating of 1,367 lbf (620 kgf) and a Timken OK Load of 60 lbs (27 kg). Under crushing mechanical forces—such as heavy bolt locking lugs unlocking under residual chamber pressure—HRCG forms an unbreakable physical cushion that prevents metal-on-metal galling and scoring.
  • High-Heat Stability & Non-Sling Cling: With a dropping point exceeding 600°F (316°C) and a base oil flash point of 485°F (252°C), HRCG won’t melt, run, or sling off vertical frame rails during sustained shooting. It stays in the contact zone shot after shot.
  • Inherent Rust & Marine Salt Shield: The calcium sulfonate complex matrix inherently neutralizes moisture and prevents rust—passing both distilled water and 1% seawater corrosion testing. It provides long-term preservation for firearms stored in humid or coastal environments.
  • 100% PTFE-Free & Non-Toxic Handling: HRCG contains zero Teflon (PTFE) or heavy metal additives, eliminating hazardous fluoropolymer fumes and providing clean, non-toxic handling for shooters.

3. Application Guide: Where to Apply HRCG Combat Grease

HRCG Combat Grease is engineered for high-impact sliding metal surfaces that experience heavy recoil, vertical storage, or extreme load pressures. Apply a thin dab to clean metal surfaces:

  • ✔ Pistol Frame & Slide Rails: Apply a light dab along handgun frame rails and slide grooves to cushion recoil impact and prevent frame rail wear.
  • ✔ Bolt-Action Rifles & Heavy Locking Lugs: Apply to rifle bolt locking lugs, cocking cams, and primary extraction cams for smooth, effortless bolt operation.
  • ✔ M1 Garand & M14 Operating Rods: Ideal for operating rod tracks, bolt camming surfaces, and receiver tracks designed around a full-bodied grease.
  • ✔ Belt-Fed & Open-Bolt Firearms: Provides maximum staying power on heavy receiver rails and feed cams under sustained automatic fire.
  • ✔ Humid & Coastal Barrier Storage: Wipe a micro-thin film over exterior steel surfaces for ultimate long-term rust and salt spray protection.
CRITICAL SAFETY DIRECTIVE: DO NOT USE ON SUPPRESSORS NEVER apply HRCG Combat Grease, liquid oils, or standard greases to suppressors or suppressor mount threads. Suppressor interfaces experience extreme thermal loads exceeding 1,000°F to 1,500°F+ (538°C to 815°C+). Liquid oils and greases applied to suppressor threads will boil off, create intense smoke, and bake into hard carbon crusts that seize the threads. Keep all greases and oils off suppressor mounts, gas tubes, and piston heads. Always keep firing pin and striker channels completely dry.
