You suck at cleaning the chamber and lubing the upper receiver bearing areas correctly: and will throw in that you may be using the wrong solvent to clean the rifle, like Hoppes that leaves a protective coating behind that attracts fouling like a magnet, or worse with mixed with CLP, become worse that pin tar instead

Use what every you want to clean the actual bore firstly (I use sweets copper solvent since it will not leave behind a residue after wards and does not require a lot of scrubbing to remove the copper fouling), then break out CLP and a chamber brush to clean the chamber, then run dry patches down the chamber and bore to leave both dry.
Note, even with the two looking dry, there will be still be small amounts of CLP on the surfaces for short term storage of the rifle.

On the rest of the rifle, use CLP to both clean it and lube the upper receiver bearing areas.
The fast way to correctly lube the upper receiver bearing areas, spray the cleaned B/C inside and out with CLP, then insert the wet B/C into the cleaned upper receiver, lock the upper home, and empty cycle the action a few times to migrate CLP from the B/C to the upper receiver bearing areas.
Bluntly, think of cleaning the rifle as more of just a CLP lube change instead (out with the fouled, in with the fresh new).


Now the important part, as you are breaking the rifle in (allowing the bearing parts to self polish out to each other), around the first 100 rounds, pull the charging handle back until you see the gas rings pass by the exhaust ports on the side of the carrier, and give the carrier gas section inside the carrier a quick shot of CLP into the port.  This will put fresh CLP into the B/C so it can be blow out at firing to migrate Fresh CLP back into the action again.  After a few hundred rounds or once the rifle has been broken in, you can kick the round count up to around 250 before CLP relubing again through the ports.
Note, the re-lube trick through the gas ports on the side of the carrier is nothing new, and been around for decades.
If you where wonder what was in the bottles on the sides helmet band bands, it was LSA/CLP for just this. Hence with a quick re-lube this way, although the rig may get slimy after a while of just adding lube without pulling it down and clean it, the rig will not fouling choke out on you.


As for CLP (which has a cleaning agent in it and will dissolve the fouling faster than it can form/deposit to choke the rifle out ), BreakfreeCLP in the large spray can is under $10, and is the best price on CLP short of buying it in the gallons or 55gallon drums through GSA.
