[R-ice]

Basically as the title states Lol, I bought an mp5 SD6 but I can't tell what manufactor made this. As I am not sure I was hoping some of the experienced people would know and be able to help me. As I was hoping to buy perhaps a "hop up system"? not sure how that works, or other acessories for it so that it perhaps last longer as I have read some of the post about barrel wobble.




Thanks the pictures are included of the AEG that I bought ...
