Looking for someone with experience with threading the barrel on a GSG5. I know the barrel has to be slightly shortened, recrowned and an adapter made to fit the inside of the FSP that adapts to 1/2 x 28. I've seen Gemtech's 3 lug adapter and don't care for it. I'm wanting their something similar to their original conversion which they not longer offer. I know Tornado Tech offers it, but was hoping to find someone local. Anyone done this before?
