Rideabike06, I have the Vortex Strikefire on my M&P 15/22 with a .05 ARMS riser for 1/3 co-witness. FleaBay has them from $9.10 to $29.00 some are true A.R.M.S. and the lesser are clones, but I have used both clone and ARMS both work. Note on the clones, you may have to file either the top riser or lower mount sometimes, I did on 1 of the clones. I'm at work, I'll post a picture tomorrow of mine with the Vortex & riser.
I've got the TRS-25 as well.
0.75" riser = absolute co-witness
0.83" riser = lower 1/3 co-witness
Hope that helps
