Well buddy hehe, I just wrote Max just now about the magazine. He had written to me and told me he hadnt built one for .177 caliber and he was in the process of looking for a tube to fit the .177 mag. In the email I sent him this afternoon I asked if he had found a tube that would work we will have to see what he says in the return email. And believe me I wanna play with it as much as you do Ian. Oh on a side note....since he hasnt made one in .177 that means he makes them for the .22 so anyone with a .22 cal QB can get one for 50 dollars US. But us .177 people will just have to wait it out hehe.
