Modified are 0.10 lower if I recall correctly. Basically the height of the dovetail. "Mistem" sent in a bunch of extra lows to get super low. They were way the hell down there. Should be some pics floating around.
That looks about right. The modified Low's that I have on my Tikka put the bottom of the scope tube just about 0.400" above the top of the rail. The Tikka spec sheet lists the "Ex-Lows" as 0.400" height. I have Leupold VX2 3x9x40 scope on my Tikka T3. "Modified" Ex-Low's (-0.100") would require that I backup the scope 1/4" to clear the power adjustment ring. Bolt handle would still clear ocular bell. However, 40mmm objective may or may not contact the barrel. A straight 6x36mm would fit without any issue. A 2.5x8x36 would probably fit as well. However, I have not tried it.
