What height riser block for AR ...

[BrocLuno]

with standard rifle A2 front sight/gas block? Assuming a red dot like a TRS-25 and you want the dot a bit above the front sight post? Co-witness plus a bit (say 1/8" visible between dot and top of front post).

My trs25 came with a riser attached, but i also got a utg med? .835 i think, which is a little shorter and cowitness. I dont use the dot on my ar anymore your welcome to the risers if you like.

That is the same height riser I have on my TRS-25. Works great and haven't had any problems with it.
