For those using Loctite 242 "Blue" for bedding the barrel extension to the upper receiver, be aware that Loctite 242 has a shelf life of 24 months unopened and 12 months after opening:

Also, be aware from where you buy your Loctite. Some online vendors state that their Loctite is manufactured in the United States. Yet, Henkel KgaA (the corporation behind Loctite) "has been operating for three decades in China, and has about half a dozen factories in the country, including one in Shanghai, which is the largest adhesives plant in the world. Sealants, epoxy, silicone and other adhesives for industrial and hobbyist use are sold under the Loctite brand":

In other words, be careful where you buy your Loctite (counterfeits exist) and that it does have a shelf life.
Lastly, here is a fascinating discussion on upper receiver lapping, headspacing and also barrel extension bedding to the upper (note the bad advice and faulty "facts" that some of the Yoda's dispel/address in their corrective posts):
