I have a two month old Trijicon Tripower (The new Aluminum one) with an throw lever mount with the spacer, both are in excellent condition. I also have a Magpul M93B (Black) AR15 stock kit. The stock kit has been mounted but is in like new shape. Looking to trade both for a Trijicon TA31F or TA11F in good shape. I would prefer a trade in the Houston, Tx area but would consider out of state if required.
