Very light oil with great lubrication properties.  Perfect of machineguns.  Unlike many other products it doesn't attract residue and turn into a paste to 'gum-up' your action.

Comes in 4 oz. bottles.

Bob Marvel’s Custom Oil is a thin bodied metal treatment that provides exceptional metal wetting and extreme pressure lubrication properties. In addition, this hydrocarbon based formula will clean your gun, repel moisture and resist corrosion. There are two qualities which separate BMCO from other gun lubricants. First, it has the unique ability to reduce carbon buildup by as much as 80%; even in suppressors, .22’s, and shotguns! Second, because of its low viscosity and lack of “solids” like Teflon, graphite and moly, BMCO functions very well at low temperatures; even as low as -50° F.! These properties make BMCO the best choice where close tolerances and/or aggressive environments compromise reliability. It is truly a unique approach to firearm lubrication.
