Ok, got the TRS-32 and mounted everything up. It works! Even in the day time, in "day mode" on the 4.5x I can see the dot fine and see out 100yds or so, haven't tried farther.
Need to adjust things back as far as possible to optimize eye relief, length of pull.
Need to improvise some sort of light shroud as, at least during the day the glare can be "exciting" off the back of the TRS-32 and that could be true on "big moon" nights as well. Such a light shroud will be a bit of a challenge, as the focus ring of the 4.5x is on the front of the objective.
I will work on this stuff and try to do some testing tonight. If this works, we are looking at a 200yd - 400yd NV rifle solution for about $400 (including the TRS-32 and the bushy 4.5x with the rifle mount). The 400yd solution might be possible in the open with either some moon or the t-20 attached, but for most conditions we would probably be limited to 200yds.
But can we hit anything with this setup? That is what we will try to determine tonight.
Will throw one of the T10 on there to test as well.
