Re: Anyone used "Frog Lube"?
I was running frog lube on my M-4 along with a Surefire 556sa suppressor. After shooting 3-4 mags through the rifle, I had a catastrophic malfunction. The bolt seized up in the buffer tube and froze the rifle. It was not a quick fix. I had to come off the line, forcibly disassble the rifle, and eventually was able to get it broken down to the upper and lower. What I discovered was there was a large build up of soft gooey carbon on the bolt, which seized it in the buffer tube during the cycling phase of operation. For the record, MY RIFLE WAS CLEAN prior to the start of the range day. I attribute the seizure to the carbon caking onto the Frog Lube. I had just started using the liquid stuff recently and had never had this happen before. I would definitely say the suppressor was a major factor in this as one round fired with a suppressor is equivelant to 3-5 rounds without one as far as carbon buildup is concerned. Another factor I believe, is it was raining that day. Im sure the stars were aligned to induce this malfunction, but I share my story so this doesn't happen to someone in actual life threatening situation. For the record, several guys on my teams use and swear by the stuff. We even budgeted for a gallon of the stuff and a croc pot to keep it heated up in. That was recommended by one of the vendors.
Just my 2 cents.
