HRO Pistol, Rimfire, Shotgun & Cold Weather (HRO PRSC) – 1 ounce

Eliminate cycle-slowing fluid drag and cold-weather cycling jams with HRO PRSC. Engineered with an ultra-thin 0W-16 equivalent synthetic viscosity profile, HRO PRSC is optimized for firearms that depend on fast slide velocity and minimal action resistance. Light handgun recoil springs, low-impulse .22 LR rimfire rounds, inertia-driven shotguns, and blowback Pistol Caliber Carbines (PCCs) frequently short-stroke when lubricated with heavy oils. HRO PRSC wicks instantly into micro-clearances, flushing out lead dust and carbon while maintaining a razor-thin, ultra-slick boundary film down to sub-zero temperatures. Keep your handguns, rimfires, and shotguns cycling at peak speed in any weather condition.

Detailed Specifications & Technical Features

• Ultra-Low Drag 0W-16 Profile: Formulated on a low-viscosity GTL synthetic base (VI 166) engineered specifically to cut fluid drag on lightweight moving components.
• Prevents Battery & Short-Stroking Jams: Guarantees flawless slide and bolt return-to-battery on handguns with light springs, .22 LR rimfires, inertia 12ga/20ga shotguns, and blowback PCCs.
• Operating Temperature Window: Optimized for ambient operating conditions from -22°F to 86°F (-30°C to 30°C), with a usable cold floor down to -31°F (-35°C) as a thin wiped film. Flash point exceeds 399°F (204°C).
• Micro-Clearance Fouling Flush: Rapidly wicks into tight slide rail channels and trigger linkages to suspend and flush away lead, wax, and carbon buildup.
• Non-Toxic & Polymer Frame Safe: 100% PTFE-free and solvent-free—completely inert against polymer handgun frames, rubber O-rings, and specialized firearm coatings.
• Recommended Applications: Semi-automatic handguns (9mm, .40 S&W, .45 ACP, 10mm), .22 LR rimfire rifles/pistols, gas and inertia-driven shotguns, Pistol Caliber Carbines (PCCs), and sub-zero winter hunts.
• ⚠️ Suppressor Safety Warning: Operating temperatures on suppressors exceed 1,000°F (538°C). Do NOT apply liquid oils to suppressors or suppressor mount threads.
