The short answer is MAYBE , the H&R's do not hold to the same specs as say a TC were in theory any barrel will fit any frame . I have found that all my barrels form say an 02 frame will fit the other 02 frames and so on . This does not always hold true but in most cases it does for me .
The FAQ's is a great place to find the in's and out's of the Handi rifle , spend a little time there and you too will understand the
addiction of these fine rifles .
