That appears to be the Canadian nipple built for the 700ml... I just ordered a couple to check, but if it is the Canadian nipple it probably will not work with the Remington hammer - you will need the Canadian hammer also...
There is a difference... You can see a picture of the kit here... what you can not see is the face of the hammer is not cupped like the Remington...
