You could cycle it a number of times, then take it down and look for bright spots where the binding is taking place.
If you are not good with small parts, the '92 action is not a good one to learn on.
The extractor would only be an issue at the very end of lever travel. It's possible that there is an issue with the ejector. The spring however is not very strong, and I doubt that's it. It could however be binding.
Mine is an original Winchester, I have no issues. But if there were some, that's where I'd look.
Also, does the rifle have a peep sight? if so, check that the screws are not too long, and binding on the locking bolts.
