Turn the gun over and clean out the channel in the rib and the top of the posts with spray carb cleaner. Flush it well. Obviously do not have the forearm or buttstock around the spray. Do not get any carb cleaner on the front bead or mid bead. Use Loctite 271 (red) and dribble several drops around each post. Leave the barrel upside down for a day or two. Not all of the Loctite will set up so clean out the channel with Q-tips. The red Loctite is more permanent than the blue.
