DHE Ejector Problem

[BRDHNTR]

I have been shooting trap lately with my 31 inch barreled Parker DHE. (and quite well I might add!). I've only been shooting it on trap using the right barrel/front trigger) On the second to last outing I noticed that the right ejector was not re-cocking. The left barrel ejector continues to cock fine.

I have re-set or re-cocked the right ejector but the minute I out the forend back on the barrel, it uncocks.

I'll probably end up taking it to Dan Cullity who is local to me but would appreciate any insights from our more experienced members on what's going on. Something broken with the cocking mechanism?

Thanks in advance
