Yep, a redesign is needed for .22LR. In the UK, .22short aren\'t that common so I\'ve redesigned my GG for .22LR.
I increased the length of the pan, the bolt, firing pin, cams, housing and possibly other bits.
If you\'re thinking of doing a LR version, I could upload all the different component plans. Or, I have all the parts designed in CAD.
Let me know.
