does anyone know which beyblade it is?
it looks like Dranzer GT attack ring but it is a HMS beyblade.
i didn't know how to upload a pic
Please upload a picture on an image hosting site (like photobucket.com) and post your question and the link to your pic again in the HMS QA thread.

Edit: Nevertheless, I assume you have Advance Striker's AR. It looks a bit like Dranzer GT.
Maybe you're referring to
Advance Striker or
Advance Averazer, but more likely the first one
I think dio (but I'm 100% sure it was him) did a custom version of Advance Averazer, so it looks like a metal system version of Dranzer GT.
