Looks as if the locking lugs on the trigger bow were NOT locked into the lugs on the receiver legs and T/G fell out with the first shot... Though I am not sure that the trigger group could have even functioned, without it being locked into the receiver... Swing the trigger bow open, set the T/B lugs into the slots on the receiver legs, floorplate should be flush with the stock at that point... push trigger bow towards pistol grip of stock and it should swing closed and snap into place... with a fairly loud click.!!!
Then cycle action, should be fine if done correctly...
HTH,
