KeithB Posted January 2, 2016 Report Share Posted January 2, 2016 molly grease or blue locktite on barrel extension before you slide it into receiver? Quote Link to comment Share on other sites More sharing options...
jtallen83 Posted January 2, 2016 Report Share Posted January 2, 2016 I use a very light coat of oil on the extension, that seemed to be the consensus when I did some searches. I use a bit of moly grease on the barrel nut threads, they just need some lube so you don't gall the threads, lots of different opinions on that subject though. Never heard of anyone recommending loctite on either myself. Quote Link to comment Share on other sites More sharing options...

survivalshop Posted January 3, 2016 Report Share Posted January 3, 2016 I use the Mil Spec. grease , light coating . about a year ago , I replaced the A2 Upper Receiver on my Preban Olympic Arms build , with a TM flat top & the Barrel had been on for well over twenty years & it came off with no problems & there was still the same light coating of grease on the Extension , I couldn't believe it myself , you would think it would burn off or something .
