    what is the biggest source of this problem? not cleaning the inside of the receiver? inside the lug area? or the bolt carrier group itself?

    Lug area is pretty important. On our rental gun there have been a number of failures due to grim build-up on the lug / bolt face area. The receiver doesn't seem to be a big issue, not as much as the crud on the carrier and lugs.

    Yes, buildup on the bolt face is really grim!

    Shooting cheap, coated steel cased ammo.

    Build up under the extractor.

    Take your bcg apart and clean the bolt face real good and inspect the extractor to ensure it is not chipped also if you are shooting laquer coated ammo take a boar brush with some sweets 7 62 solvent and give the boar where the lugs are a good scrubbing.
