Well, I recently purchased a Nightforce tripod and was quite happy with it... until I tried to find some attachment plates. I looked for the size everywhere and could not find any info on their site so i figured it would be a standard ARCA Swiss plate. I bought some plates and they were too small. The ARCA Swiss measured 1.5" and the smallest the Nightforce plate would go down to is 1.6". So i called Nightforce and they told me they don't know what plate they use and would be happy to give me a machinists number local to them to mill me a plate?!? Seriously? Nobody at Nightforce had a clue as to what type of plate they use for the tripod. I tried a Feisol gun mount and same problem, too small. Nightforce told me to call one of their vendors for parts for the tripod and i told them that i already looked on the sites of their vendors and no one had parts, just complete tripod set-ups. I was told they should have plates. I called Eurooptic and they told me what I suspected, they only carry the complete tripod... no parts. They offered to take it back for a 20% fee?!? I never would of bought the damn thing if in knew the tripod head didn't take a standard plate size. I would of checked before buying but the head size isn't listed anywhere so i assumed it would be standard. Enough bithcing on my end. Don't buy the Nightforce tripod.
