YMMV, but this particular red dot didn't work for me, on this Henry .22 - because it has a line-of-sight so high that I had to raise my head/cheek entirely off the buttstock to view the dot.
Not exactly conducive to either accuracy or speed.
The sight body is at about the height of a normal .22 riflescope, with the red dot lens above that.
The sight would work, however, on a rifle with either a higher/straighter comb on the stock, or one with a monte carlo comb - like the Henry .17cal levergun.
Oh, well - at least it was an inexpensive lesson, unlike most of my past lessons.
