Check this out TF2 Teflon spray, been using it a while after mate gave me a can. Got simbols on the side like hinge, gear & a rifle! Use it on all parts & bolt is real silky slick! Notice it stsight away & it lasts. Cheaper on the bay.
I have been using the WD40 PTFE spray for a number of years. Quick spray of the bolt after cleaning, leave to dry (a max of a couple of minutes) and your ready to go. It isnt sticky and dry's completely.
