The high level claw mount that TM did was a copy of a RS item. The real ones are now pretty affordable as they have fallen out use in favour of the lower profile screw down mounts due to their weight and the fact that the newer style mounts give you a much lower height over bore, so a noticeably smaller shift in zero at close ranges. I often see them going for not much money at airsoft sales or on various selling sites. However unless you are going for an authentic retro build I wouldn't bother.
I have a pair of WE apaches that I run eotech's on and I just used the following from Amazon, they work well are as cheep as chips and you can get it delivered free next day if you have Amazon Prime.
