I recently replaced the charging handle on my Winchester 1400 12 ga. The only reason it was replaced is because the finger tab broke off of the old one and it was a pain to pull the bolt back. I purchased a part that was listed as new and it seemed to drop right in. Now anytime the bolt is back it is binding up and does not go forward unless it is pushed. Is there a difference between year models? The only thing I can see that is visably different is my old one has one more hole in it. the area at the top of this one that is in set is a hole in the old one does that make a difference?
Did you find answer? Looking for same information.
Sometime they require hand fitting.There is an excellent video online which shows how to do it.
