Modify Baton Ryusoku Flat Hopup Bucking for Airsoft AEGs (Model: Soft)

"I just got the thing and put it in my gun and a bb snagged it and ripped it. I was using .20 like it said to. The nub was a pain to put in as well. I would not get this it was a waste of money. If u flat hop your gun let someone in evike do it for u. I give it one star cause it couldn't get through one mag.
