Is that a 94 Carbine? If so, please don't chop it if it is still in original condition. If it is in good condition, you could very easily triple your money on it.
If it is a 94 Carbine, the thread on the end means that is was imported in the 1960s and had a small barrel extension placed on it by the importers to meet barrel length restrictions in place at the time.
Seriously, I know some people just view rifles as a tool, but a 94 Carbine is not one of the military rifles to cut up. They are getting rarer and more valuable every day.
