Fits wonderfully on my soda stream refills which I stopped using during COVID as it was impossible to get supplies. I was actually thinking of recycling them to just get rid of them but the I bought the CoolFire and now I have a whole new reason to use them. They work great and the adapter is essential!

Gives me a better recoil simulation during dry fire especially when combined with the Mantis System!
