I didn’t get one of their recommended tools to tightened down the lock ring. The spanner I have doesn’t get a good bite into the shallow notches in their lock ring. So for now I’m going to use the lock ring from the RX Comp and swap it back back and forth. It works just fine.
I'll be comparing the gen 1 three port to the sico on my hybrid 46 on a .300 norma. I'm really interested to see if the larger diameter 2 port sico can beat the 3 port rx
