My lubing process is pretty simple.
1. CLP on anything that mechanically moves.
2. While in the safe: Light film of Walmart Super-Tech Moly-Lithium Grease. Only on mechanical externals like bolt carrier, charging handle, and hammer/trigger (Internals like bolt and firing pin just the CLP). Tube of Moly-Lithium grease is a couple dollars, and will last your entire lifetime; your child's lifetime; and probably your grand child's lifetime.
3. Just prior to shooting: Spray more CLP on ALL moving parts. Basically; just spray the crap out of the rifle and wipe off the excess.
After shooting:
1. Bore Snake the barrel
2. Powder blast or similar the trigger/hammer area and chamber area of the barrel. (Brush if necessary)
3. Field Strip Bolt carrier assembly.
4. Powder Blast or similar all parts disassembled.
5. CLP spray lube ALL mechanical parts (Step 1 in first section above)
6. Reassemble gun.
7. Super-Tech Moly-Lithium grease external mechanical parts (Step 2 in first section above).
8. Put gun away in safe.
Prior to shooting; go to Step 3 in first section above, and repeat the process.
The reason I use the Moly-Lithium grease is because it WON'T run out. It allows you to have a long term lubricant on the gun when stored or when just tinkering with it at home. It's very inexpensive. There's a lot of it in a tube. And it's removed easily with powder blast or similar.
Total cleaning and lubing time for me is less than 10 minutes. That's after an average shooting of about 500 rounds.
