Because of this, with an allen wrench, the owner can replace the barrel with a 77/22 barrel. To use a 10/22 barrel, the process is the same as converting a 10/22 barrel for use in a 77/22. Both the 77/22 and 96/22 have dual, opposed extractors. A slot for the left side extractor must be cut into a 10/22 barrel to use it in a 96/22 or 77/22. [3]
