According to the manual referenced, Browning recommends cleaning the barrel and the inside of the receiver as much as possible without disassembly.

I wound up getting the take-down PG version which is more user-friendly and allows you to clean the barrel from breech to muzzle.

I would agree with ATR (Rick) on not disassembling a BLR otherwise it is easy to screw up the gear timing and one has big issues. If you really have to, find a gunsmith who is a Browning dealer and let him look after it.
