Howdy, I'm on Manners' Stock Builder site and it lists inlet options for both the T3 and T3x. I'm looking to order a MCS-PRS1 TK, but I have both a T3 and a T3x, and I need to know if the stock will work with both rifles. My understanding is that the footprint is the same, what am I missing?

Thank you,
BP
