My son was given a Browning Citori shotgun at his work for 20 years service a few years ago and placed it in his closet. The other day we took it down and tried to put it together, but with no success. We read the instructions over and over, but apparently we are missing something. We can attach the barrel but cannot get the front forarm to snap shut. This is a $5000 gun and I wouldn't think it would be that difficult, so I think we are overlooking some little feature. If there are any Browning or Citori experts out there, maybe they would know exactly what step we are missing. We don't want to force anything for fear of damaging this beautiful firearm. Help. Thanks.
