I have a 16 gauge Trap grade that I am unable to remove the barrels. Top lever goes all the way to the right and barrels release, but will not open. I removed the for-end and hammers were in correct position, I tried to remove barrels with out for-end and had no success. Any help would be welcome. The gun functioned perfectly last time I had it out. I have no gunsmith skills and am not very mechanically inclined, perhaps this is a job for Jerry Andrews.
