    I have all the parts ordered & on their way. I'm just about ready to start assembling, & I've seen alot of tutorials to get me started. But I have not seen a definitive guide on what should get lube during assembly, & what should not. Can someone help me out here? I've heard some say: Any place where metal contacts metal should get lube. Is that accurate?? Thanks

    Make sure there is no oil in the barrel before shooting. It will mess up your first shot. This is what we call the "oil shot" in Germany. The bullet will go further to the left or right depending on the direction of the rifling.

    Your very welcome. The experts here will chime in and add their experience, but I just follow these as a guideline.

    I disagree with two points;

    The gas rings are NOT to be lubed with an oil/grease. A dry graphite type lube is OK. Oil on the gas rings will turn to sludge after a couple of shots.

    I like to run my firing pins dry.

    On thing that I had to learn from my own that I would like to share is. Invest in a chamber brush (under $5) and clean that chamber with some solvents of a new barrel real good! I had just built a Adams Arms piston build from the ground up and was shooting steel cased Russian ammo and was getting shells stuck every 10 to 20 rounds.

    Get some fireclean, pretreat everything. Wipe off the excess. Shoot. People tend to over think lubrication and maintenance on an AR. I personally don't hardly ever clean mine. Put lube on it and it will run. Who cares about sludge or carbon build up? Shoot the thing. If you have a milspec+ rifle, it will run absolutely filthy. Fireclean is the best product I've ever used. Slip2000 EWL is second. Fireclean doesn't burn off like slip because it's not oil based. Just keep her well oiled and she'll go. Don't make her a safe queen.

    Another reason I like Mobile 1 synthetic , I use it on my gas rings and no gummy goodness , I dont lube my firing pin either , no need to, no further than it moves and why take a chance on carbon buildup and oil that could cause a issue

    I also use Mobile 1 synthetic. And don't lube the firing pin or buffer spring. Otherwise I'm pretty generous with lube.

    Use CLP as shown in Anna's great illustrations.

    Everyone has their own recipe, but I follow the Field Manual advice.

    I'm thinking some racoon fat, TSP and Vinegar would be worth a try, that is if I can't trust the Field Manual.

    I like Mobil 1 also but use Sentry Solutions dry lube on the gas rings. Even if the Mobil 1 will not gum up, it will collect carbon in the gas rings that WILL gum up.

    I just can't figure why it matters if it "gums up" on anything on the bcg. With lube it WILL run. And run reliably mind you. I've tested this theory. Lube and forget.

    I use Yamalube synthetic 15w-50, purely because I traded my bike off to a dealer and still have the oil for it lol.
