Both old and new style will make the ratchet sound.
Take your magazine cap off. Look at the mag spring retainer as it currently sits in the end of the magazine tube (where the cap just came off). Is it black plastic with a slot in it? Do you see ridges on the mag spring retainer? If the answer is yes, then that barrel will be fine.
If the answer is no, then the answer is maybe. If your mag spring retainer is flat, smoth, metal, you will have to call and find out if the barrel they sell has the detent protruding from the barrel guide ring.
There has to be a system that will keep your mag cap from loosening.
