northern glock guy
Copper BB
Hi there folks this is my first post here. I have been a 590 and now a 590A1 fan for many years now. currently I have a 590a1 mariner that I gun koted flat black with a marble arms trijicon bead. My old guy eyes arent picking up that monster bead and the center of the reciver relationship like it used to. So I am entertaining getting some sort of sighting arrangement equipped 590A1. how adjustable is the dot system on the 53690? and are you guys happy with the sight pictures ease of aquisition? I compensate for myopia on rifles with all sort of aperature approaches. on handguns I rely on 3 dot arrangements to compesate for near sightedness. Any input or suggestions on this sight or other mossberg sight options is greatly appreciated . Thanks
