Narrative:
Upon receiving three B787 oxygen bottles. I; aircraft maintenance technician (amt) in ZZZ inspected these bottles before putting them in service. This is normal practice in ZZZ. It was at this time I noticed one bottle was low; one was empty and the other was at 2000 psi (normal). My investigation revealed that all three bottles had damaged (bent) gauges. All three is alarming to me. I have attached photos of all three bottles along with the non-rotable parts tags. There needs to be an investigation to determine where the damage is occurring. And we need to check all B787s to determine if they are flying around with damaged bottles. Flight deck crew. Component.
