If my memory is right those little grub screws are 2 mm , you can get a small box of them for less than 10 bucks from a commercial bolt and nut scource. I think there was like 15 or 18 in the box. I still have a box of them around here some where...

2mm sounds about right. I'm not to concerned with it right now.

Does your 124 produce better velocity with AA pellets versus the JSB's ?
Mine shoots the JSB 8.4 @797 fps versus 810 fps for the same weight AA.
And both are equally accurate.

I referring to my R9 .. I just shoot cphp
