and I'll look up these nodak irons, this rifle is a howa mini in a Stocky's carbon stock, the optic set up would be identical to do on my murican ranches but I have pulled the rails on those for talley lightweights lows and trijicon accupoint 3-9x40's, that optic gives about a 3.8 moa dot with that eye relief and I shot it just as tight at 200 yards on the bench as I did with fixed 6x on the same rifle, maybe a little tighter actually, dot covers about 7-8" at 206 yards, still fits inside the kill zone and trajectory can be set so the bullet stays within the dot to mpbr, the pro's over irons is the 360 degree view around the aim point, seeing under the dot is helpful, and quick but also for hold overs or overall perception and seeing the full target area not just the top half
edit, looked up the Nodak irons for ruger American ranches...brilliant!!!
