I saw on their website they have a 34mm 20moa scope mount for the TRG and AI. It has a built in level for cant that can be supplied with tritum, which is pretty cool. So my question is has anybody used this? What do you think? Does this connect to the receiver or do you still need rails? I am guessing it does because it is made for the TRG. Any help appreciated, before I lay down some big buck for this thing.
