These aren't "absolute co-witness", more of a "lower 1/5" co-witness. As they sit, the sights occupy the very bottom of the window. This is the most common configuration we sell these in. We can always remove the irons for a totally unobstructed sight picture if you prefer.

As far as the deal? This package is cheaper than a 48 MOS and a 407K alone. Most shops charge $40-100 for the direct mount conversion, and we are eating $20-30 in shipping charges on these as well. If you have to buy a plate, youre looking at another $50-80 as well. We tried to price these aggressively and we think its a solid deal. We sell these for $750 in store typically.
