This is the rail I currently have and vastly prefer. I don’t currently have anything on the picatinny rail portion. Alpine Rifles currently has my stock installing additional QD attachments on the sides (the one I got didn’t come with them). I carry a Spartan bipod with me on my bino harness since it is impractical to carry a backpack all the time. When I go walking or hiking around my farm, I now wear the bino harness all the time, but wear a camelback rather than a backpack.
These are some of the pictures of the Trinity rail. I don’t like it one bit. Each portion is too small to be useful. For instance, the picatinny rail is too short for most bipods. The Spartan hole is too close to the QD hole. I traded my Trinity rail for the other one.
