I dont typically bash products, but on this one I'm just going to come out and say it. This stuff is horrible. in the last 3 days I have seen 5 guns gummed up from this crap. The oil has turned to a sticky sludge. To the point of being able to cycle the gun is difficult. Some of them are pumps some are simis. Various brands of guns, rifles and shotguns. The auto's the guns bolt would slowly cycle forward and not fully close causing misfires, the pumps would just be difficult to pump and they would stick. Then cleaning the residue off is a pain in the rear.
I know part of this is a routine maitenance issues but please take my word and a few others words.
Look at the FP-10 oil, Millitec, and a few others. You will lead a happier hunting season especially if its cold outside.
Thank you and have a nice day.
