Some of the SW5 guns had out of spec bolt carriers and cocking tubes.
I had one where the bolt carrier upper was a bit short- but still worked fine (.5" fudge factor to play with). In order to fit an in-spec bolt carrier, the cocking tube had to be shaved down.
If a bad enough combo of parts got in there, I could see your problem happening.
A new bolt carrier or cocking tube may fix your issue, but if they set the stop piece for the cocking tube too far back, you'll have false bolt gap issues. Ideal fix if that happens is to un-weld the stop ring and weld it back in the RIGHT place.
Best to let an expert check it out, or someone local who knows what they're doing.
