Product Description


AR4200 is a cleaner, lubricant and corrosion protector. AR4200 is a unique formulation of synthetic oils and additives specifically formulated to provide exceptional protection against wear, rust, saltwater corrosion and fouling. The natural solvency of the synthetic oils and nano cleaning additives remove all surface carbon and lead through a process of chelation. AR4200 utilizes nano tungsten disulfide (WS2) which is one of the most lubricious materials known to science with a coefficient of friction measured at 0.03. Velocity increases of 6-8% are not uncommon.

AR4200 forms a dry and extremely hard surface with a load carrying ability of 300,000 + psi, has a temperature range of -54°F to over 1200°F and requires no heating or curing. There is no lead or carbon buildup due to the extremely low COF. The WS2 surface repels dirt, dust and even salt water. AR4200 reduces jamming and will not gum up or lose its viscosity under extreme temperatures. AR4200 meets and exceeds military specs passing the 2000 hour salt spray corrosion test, base fluid operation to 600°F and WS2 operational to over 2000°F. AR4200 is superior to PTFE, moly, graphite and silicone based oils. Nanotechnology reduces elements to the level of parts per billion thus providing enhanced coverage and performance characteristics.


  • Reduces Friction and Heat
  • Prevents Deposit Build-up
  • Prevents Jamming
  • Increases Velocity
  • Prevents Corrosion




  1. Saturate a cotton patch or mop with a few drops of AR4200 CLP. Pass through the barrel 15 - 20 times. Use long slow strokes ensuring you get complete coverage from muzzle to crown. If required, let AR4200 CLP work on fouling for 5-10 minutes.
  2. Apply a few drops onto a nylon brush and run through the barrel several times to loosen any stubborn fouling. AR4200 contains no ammonia so no need to neutralize.
  3. Use 2 - 3 dry cotton patches and push through bore to remove any excess lubricant. This will also ensure any remaining fouling is removed. Buff off excess for a dry and super-smooth finish. This gives the barrel a hard, dry film capable of withstanding high temperatures even under extreme conditions.
