Nimrod Extreme Performance Black Gas 500ml - The Ultimate Pressure Solution

When the temperature hits rock bottom or you are running a heavy-duty gas blowback rifle that demands maximum output - Nimrod Extreme Performance Black Gas is the ultimate solution. Rated at a formidable 175 PSI - this is the most powerful gas in the Nimrod range. It is specifically formulated to combat extreme "cool-down" and to provide enough kinetic energy to cycle heavy steel bolts and reinforced gas systems in the harshest conditions. This is not your average propellant - it is a high-pressure specialist tool designed for the seasoned player who refuses to let the British winter shut down their game. Containing a high-purity mixture and essential silicone lubricants - it ensures that even under massive pressure - your internal seals remain seated and supple.

Key Features and Performance

• Extreme 175 PSI Pressure - The highest output available for maximum cycling power and FPS stability.
• Sub-Zero Performance - Engineered to remain effective in temperatures where Red and Green gas simply cannot expand.
• Enhanced Silicone Content - Extra lubrication to offset the high-pressure stress on valves and O-rings.
• Heavy Bolt Optimization - Ideal for GBBRs and rifles with high-tension recoil springs that require maximum force.
• Reinforced Metal Nozzle - Built to handle the internal bottle pressure and provide a secure - leak-free fill every time.

The "Pro" Take

Black Gas is the "nuclear option" for GBB enthusiasts. I tend to reserve this exclusively for the peak of winter or for specific platforms like the Tokyo Marui MWS with heavy aftermarket bolts. If you have ever felt your rifle get "sluggish" during a damp - freezing morning at a woodland site - this is the fix. It provides a level of recoil and "snap" that is unmatched - making your RIF feel alive even when the ground is frozen. It is a high-performance product that requires respect - it is about keeping your gun running when nothing else will.

UK Spec and Site Performance

In the UK - managing your power output is critical - and Nimrod Black Gas requires a watchful eye on the chrono. Because our typical site limits are 350 FPS for full-auto and 450-500 FPS for DMR/Snipers - Black Gas can easily push a standard RIF over the legal limit if used in mild weather. It is perfectly suited for those crisp - 0 to 5-degree days at large-scale woodland sites across the UK where you need to maintain range and consistency.

As this is a high-pressure propellant - it is exempt from UKARA requirements for purchase - but you must be 18 years of age. Given the power - we always recommend checking your site's specific Joules/FPS rules - especially if you are transitioning from a summer setup to a winter "Black Gas" configuration. For heavy GBB DMR setups - this gas is the industry standard for maintaining that long-range "reach" during winter operations.

Friendly FAQ

Can I use Black Gas in my standard GBB pistol?
We strongly advise against using Black Gas in standard pistols - especially those with plastic slides or stock alloy slides - as the 175 PSI pressure can cause catastrophic failure to the blowback housing or slide.

What is the ideal temperature for Nimrod Black?
This gas is designed for "Extreme" conditions. It performs best when the ambient temperature is below 5 degrees Celsius. Using it in warm weather (above 15 degrees) can be dangerous for your equipment.

Does it work with "Gas-in-Mag" Sniper Rifles?
Yes - this is often the preferred choice for gas sniper platforms during winter to ensure consistent FPS and hop-up application over long distances.

Will this gas damage my seals?
Nimrod Black contains silicone oil to protect your seals - but because it operates at such high pressure - you should perform more frequent maintenance and lubrication on your mags compared to using Green Gas.
