What Spuhr mount are you guys running on your ZCOs? I'm between 6001 and 6002. Only concern I have is if the 6001 provides enough bolt clearance on the 90 deg bolt throw of an Impact 737r action.
I have just bought the 1.5” ZCO mount because I’ve got the 6001 on my AX and had to remove the top rail. Currently left the Spuhr because it looks better
