Ok, just trying to glean some usefull info from some of the vast displays of  knowledge... specially since I am new to AR's. In one of the other Milspec is this...no it is this.... discussions I saw the topic of dry lube in buffer tube come up a few times. I just bought some Break Free CLP and need to know if I need to add something else to my arsenal of support stuff. What kind of dry Lube?? Is CLP ok for buffer tube or dry lube better?? Thanks.

I beleive a mil-spec receiver extension be it carbine or rfile will have the grey baked on dry lube like the inside of a good upper,Bushmaster or Colt.It dosent need lube but from time to time I wipe it out with a lightly oiled rag.CLP is all I use to clean and lube and every 2000 rounds I use a stronger copper solvent in the bore just in case so nothing builds up,other than that CLP is good on any part of the rifle.

Thanks for the info, That is what I will probably do.
