OK.... so this turned into a bit of sh*ticane...
First, let me thank you all for your kind advice and information.
Secondly, let me state that i am feeling fairly stupid at the moment and i am fairly hesitant to relate this story, but what the hell...
The cleanup of my new rifle went well, it is cleaned, greased and good to go.
HOWEVER... the other rifle, an older one...what a nightmare.
i stripped her down as per the "M-14 complete assembly guide" and bathed all the components in a bath of biodegradable engine degreaser. I basically stood the receiver up in glass container so it was submerged to the point that the fluid just touched the base of the barrel where it protrudes from the receiver.
Well... and here is where i will look stupid... the previous owner had the thing painted/coated in something (the receiver and op-rod) i failed to recognize what would happen (yeah i know). Came back about 3 hours later and the paint had basically bubbled/wrinkled and come off.
So i curse a bit and pulled the parts out of the degreaser, attack the ones that were painted with some shop towels, a brush, and air blaster from my compressor and, thank god, the whole thing came out OK, i think. I spent a good couple of hours cleaning everything. every last bit of the paint/coating the last guy put on it is gone, its clean as a whistle....but the finish looks like sh*t, when i compare it to my new rifle (a 2007 from marstar a few weeks ago) it almost looks like it has no finish.
I will post photos sometime on Sunday when i get a sec, but for now, im really not sure if i totally screwed it up or if i just need to put a good coat of oil on it and it will come back to life?!!! someone with some experience can chime in here with there opinion please?
i was not a happy camper this afternoon. Oh... and on top of all that i broke the goddamn windage assembly knob.
