Revolutionary SCS from Proto.
A jewelry made in US: quality and irreproachable finish.
Very optimized via its original shape, which allows it to gain a maximum of weight.
M8 screw (FINALLY) and tightening with a 6mm allen key!
+ For the first time, an additional screw which allows the SCS to be moved apart to facilitate its assembly / disassembly.
It's the perfection. Compatible only in 31.8mm
