FINALLY! A product that said, "Yes, we can make a butt-stock that will work with any airsoft platform!" This is a well made product that looks great and works great. I can use it on any and all of my guns including KWA where I have to accommodate the fuse. I really don't have enough words to express how happy and impressed I am with this product! If you buy it - you will never buy another butt-stock product. Simple to use, simple to install, simple to change out (any) battery configuration! Bottom line - BAD ASS!
